2.1.1. Circuit Component 1 (Power Source)
The energy-circuit begins with a power supply. For safety and stability, a direct current (DC) power supply with a fixed voltage is commonly used. However, this paper explores the flexibility of the system by considering alternative power sources, such as variable DC supplies and those with different voltage ratings. To accurately model the energy-circuit’s behavior, it is essential to understand the initial current provided by the power supply, as well as the resistance and material properties of the connecting wires. This knowledge allows for a more realistic representation of real-world conditions,
2.1.2“. Circuit Block 1” (Initial Exploration of Ohm’s Law)
This initial section of the energy-circuit diverges from the traditional demonstration of Ohm’s Law
, which is typically characterized by a linear relationship between voltage, current, and resistance in conventional electrical circuits. In “Circuit Block 1” the focus shifts to exploring an innovative configuration involving three identical diodes: Diode 1 (
), Diode 2 (
), and Diode 3 (
), as illustrated in
Figure 3. In this uncommon parallel circuit configuration, the positive terminal of the power supply (
) is connected to the anode of
. The cathode of
branches into two paths, one leading to the anode of
and the other to the anode of
. The cathode of
is connected to the negative terminal of the power source through a ground node, while the cathode of
is connected to the input of the next circuit block. Although
and
share a common anode (from
), they are not in a conventional parallel configuration, as their cathodes are connected to different nodes. Throughout the subsequent sections of the paper, this new circuit configuration will be named as the “
short-parallel connection”. This “
short-parallel connection” creates distinct operational behavior:
, connected to the negative terminal of the power supply (
), provides a forward-biased connection loop that completes part of “Circuit Block 1” through the ground, while
continues the energy-circuit to the next sections, introducing the parallelism aspect. The primary role of
and
is to prevent unwanted current backflow, especially when
is subjected to an electrical short circuit (Definition 1). This configuration effectively mitigates undesired feedback, a common issue in standard circuits during short circuits. To understand the behavior of “Circuit Block 1”, this section establishes the operational framework using the diode equation, (Equation 1) as applied in [
40,
41]. This equation describes the current-voltage (I-V) relationship for a diode, essentially establishing how current flow through the diode changes with applied voltage.
In which;
is the diode current,
is the reverse saturation current,

and
for the voltage across

and the forward voltage drop for
as
. These notations leads to computing the voltages in “Circuit Block 1” as;
for the forward voltage drop of the diode
. Since
is connected to ground at the cathode, the voltage across
, denoted
, is the same as the voltage at the cathode of
:
. The voltage across
, denoted
, will be similar to
since they share the same anode:
. Again, for the described circuit configuration, the total current output from “Circuit Block 1” to the next Circuit Block (denoted as
) is the sum of the currents through
and
because both currents contribute to the input of the next circuit. The current through
, denoted
, is given by the diode equation:
. The current through
, denoted
, is similarly given by:
. Lastly, the current through
, denoted
, follows the same form:
. Therefore, for two diodes (
and
as depicted in
Figure 3 we have;
and
implying:
Substituting Equation 1 (the diode equation) in Equation 2 for the “
short-parallel connection” diodes configuration;
Combining the like terms in Equation 3 and factoring out
we get;
Equation 4 represents the total current flowing through the diodes in the uncommon “
short-parallel connection” circuit configuration, (“Circuit Block 1”). Further, the total voltage fed into the next Circuit Block from both
and
(denoted as
) can be approximated according to Equation 5:
As depicted in
Figure 3, the diodes
,
, and
are configured in unique “
short-parallel connection” designed to prevent undesired backflow of short circuit current from “Circuit Block 2”, when the energy-circuit is implemented. When a short circuit occurs, the excess current attempts to flow in reverse, causing all diodes to transition into a reverse-biased mode. In this mode, the depletion region within each diode widens, increasing resistance and effectively acting as a barrier to reverse current flow. In this circuit configuration,
plays a crucial role in ensuring that the connection (L) from
to the junction between
and
does not provide a path for the excess short circuit current to flow back to the negative terminal of the power supply. During a short circuit,
’s connection to a more negative terminal of the power supply prevents any reverse current from returning to the power source, thereby safeguarding the circuit. Therefore, as the short circuit affects the circuit,
,
, and
all become reverse-biased.
’s reverse bias prevents current from flowing back into the positive terminal, while
and
, despite sharing a common anode, act as barriers at their respective nodes-
to the negative of the power source and
facilitating the excess short circuit current to the next circuit block-effectively preventing any unwanted current backflow and maintaining circuit stability.
Figure 3 illustrates this “
short-parallel connection” circuit configuration model, where the coordinated action of all three diodes is meant to ensure a robust protection against short circuit conditions, as demonstrated in
Table 1 and Figure 5.
Definition 1 (Model of Diode Idle State or Inactive Mode). In the context of “Circuit Block 1” (
Figure 3), a diode’s idle state occurs when it is reverse-biased but not actively conducting. In this mode, the diode behaves as a passive element, essentially a closed switch, until a load is applied. Diode
in
Figure 3 demonstrates this idle state. During a short circuit, the diodes effectively function as a barrier with infinite resistance, preventing reverse current flow
In practice, utilizing Equation 4 requires specific parameters for each diode in the energy-circuit, including forward voltage configurations ( and ), ideality factor (), and reverse saturation current (). Considering the foundational principles for “Circuit Block 1”, does not contribute to the forward voltage of the next block circuit. Therefore, the subsequent analysis will be based on the forward voltages and , over the expression: . This observation preserves conformity with theoretical foundations, reserving as “Circuit Block 1” protection component during the electrical short circuit. Therefore, within this context, “Circuit Block 1” plays a critical role. It employs these diodes to prevent current from flowing back to the power source, safeguarding the integrity of subsequent stages. In contrast, “Circuit Block 2” introduces a controlled electrical short circuit, a design that anomalously results to an excess current. If this short circuit current were allowed to return to the power source, it could cause damage to the energy-circuit. The overall effectiveness of “Circuit Block 1” in preventing this backflow relies heavily on the initial power supplied by the types of diodes applied in the circuit. Consequently, the specific one-directional current components chosen for “Circuit Block 1” can vary based on the specific application’s power demands. Further, the components including; typically the diodes, are not characteristically fixed but can be tailored to the unique characteristics of each application, enhancing the overall versatility of the energy-circuit.
2.3.4. Short Circuit (“Circuit Block 2”)-Experiment Design
Three distinct experimental configurations were employed: a short circuit control experiment, an induced short circuit experiment (replicating natural electrical short circuits), and a simulated short circuit experiment. All experiments utilized a standardized apparatus consisting of a
DC power supply, an ACS712T 20A current sensor module, three
1N5408 power diodes, and an Arduino Uno, carefully selected for safety and simplicity. Notably, for the control and the induced short circuit experiments, the power supply selection was informed by a simulation approach based on a Modified Ohm’s Law equation [
19].
The Modified Ohm’s Law. The Modified Ohm’s Law, as presented in [
19], provides a more accurate model for predicting and quantifying short circuit currents and voltages in both ideal and experimental conditions, particularly for low-resistance applications. This model proved invaluable in determining the appropriate initial power supply input for various diode types during the experiments. The short circuit current, denoted as (
), was initially simulated and calculated using the Modified Ohm’s Law current formula (Equation 6). Unlike the Standard Ohm’s Law, which would be inaccurate for the low-resistance conditions of a short circuit, the Modified Ohm’s Law is specifically designed to handle nonlinear circuit behavior. Equation 6 served as a crucial tool and experimental resource for accurately predicting the electrical short circuit current and circuit materials requirements within our energy-circuit.
Where:

is the change in resistance from its reference value .
In this context,
, where the standard circuit resistance (
) is considered to be a function of the parameter (
) as established by [
19]. Theoretically, using Equations 5 and 6, the power input to “Circuit Block 2” can be calculated using Equation 7.
As previously noted, one of the primary objectives of “Circuit Block 2” is to generate excessive short circuit current and efficiently direct this high current to the subsequent stages of the energy-circuit. The short circuit connector (the resistive element shown in
Figure 4), often termed the resistive element, plays a pivotal role in achieving this goal. It not only establishes the short circuit in tandem with “Circuit Block 1” but also contributes in ensuring that the high short circuit current flows forward in the energy-circuit without causing damage. In the essence, this resistive element becomes the first path of low resistance after the electrical short circuit, preventing the excess current from finding its way back. Therefore, the consideration “
resistive element” is a practical signature to ensure that in an experiment, this conductor is relatively within the same resistance to other conductors (connection codes) in the circuit. The circuits dual role is crucial, as the resistor, in collaboration with “Circuit Block 1”, prevents undesired backflow, while its high resistance directs the abundant short circuit current toward the next stages. To validate the operation of “Circuit Block 2” in this paper, the resistive element will be assumed to have the same resistance as the other connecting cables used in the described experiment. Importantly, “Circuit Block 1” current and voltage outputs transition to become the inputs for “Circuit Block 2”, maintaining the uninterrupted flow of power and energy throughout the energy-circuit’s progression. Further, we take into account the effective resistance in the “Circuit Block 2”. This resistance will include the overall resistance in “Circuit Block 1”, and it can be computed following Equation 8.
It will then be considered that the combined resistance (named subsequently as
) between
and the resistance of the high resistive component facilitating the short circuit also contributes to ensuring the forward flow of current, from “Circuit Block 2”. For practical purposes, this resistance can be expressed following Equation 9.
The focus then shifts to understanding the practical significance of the resistance (). Through the experiment, the physical significance of the quantity will be understood based on the overall power output from “Circuit Block 2”.
A Practical Relation between the Experiment and the Modified Ohm’s Law. Again, to verify the functionality of “Circuit Block 1” and “Circuit Block 2”, the value of
, which is in a direct proportion with the
has to be determined either based on experiment materials or through simulated experiments. As provided by [
19], several factors including: material properties and experimental conditions affect the choice for the parameters
and
. This section will consider only the experimental conditions (temperature and low resistance circuit type). The verification experiment was conducted within room temperature at
, using 1N5408
type power diodes. For an ideal circuit, Equation 6 demonstrates that the magnitude of the short-circuit current depends on the initial power supply voltage. For example, with a simulated supply voltage of
and a reference resistance of
the output short-circuit current will be;
. This calculated current must not exceed the minimum current rating of the diode. The chosen 1N5408 power diode has a current range of
. For simplicity, we will operate at the minimum current of
. The power supply selection followed the criterion established in case 1.
Case 1 (Determining Minimum Supply Voltage). To determine the minimum experimental supply voltage, we set the diode’s minimum operating current to approximately using Equation 6.
Where:
.
, is current scaling factor.
.
is the change in resistance from its reference value .
Since , we can substitute this into the equation: .
We then proceed in an assumption that does not distort the genetic design of Equation 6, by considering the case of a pure electrical short circuit hence the , and the exponential term becomes , so the equation simplifies to: . Therefore, . Substitute known values; . Simulated analysis of this power output results is provided in the supplementary materials.
This calculation justifies the experimental framework depicted in Figure 7.
Figure 4 shows the “Circuit Block 2” configuration, which was automated based on the circuit design in Figure 7.
Investigation 1. Automated measurement of the short circuit current. The energy-circuit verification experiment involved connecting a
DC power supply to a circuit containing three power diodes (1N5408) and an ACS712T
range current sensor module, all integrated with an Arduino Uno. The goal was to observe the behavior of the proposed energy-circuit under different short circuit conditions. To verify the creation of excess power, the experiment involved analyzing the response of the diodes during a short circuit introduced between two specific nodes (
and
) in the circuit. The excess generated current from the short circuit configuration was used to assess whether excess power was being created. The setup started with the positive
terminal of the power supply connected to the positive pin of the current sensor, while the negative of the power supply was connected to the negative pin of the sensor. Diode
was connected from the positive supply to its anode, and its cathode branched out into two paths: one leading to the positive terminal of the next circuit, and the second path running through the anode of diode
. The cathode of
was connected to ground, completing the path to the negative terminal of the power supply. Diode
was also introduced, with its anode connecting to the same point as
’s anode. However, its cathode was routed to the negative terminal of another circuit. To measure the current and voltage during the short circuit event, a connection was made between
and
(nodes
and
) using a short circuit connector, forming what was labeled as “Circuit Block 2” as depicted in
Figure 5. To measure the short circuit current, a connector was routed between the current sensor's (
) pin to pin (
) of the Arduino to measure the current, and voltage readings were taken by connecting node
to pin (
) of the Arduino via the current sensor’s (
) pin. The experiment provided an assessment of how the circuit’s ability to withstand short circuit conditions while protecting the power supply and to demonstrate the potential for excess power generation. First, current and voltage readings were recorded at
-second intervals for
seconds, both before and during the short circuit event. The experimental results are summarized in
Table 1.
Figure 5 provides a block diagram of the circuit used in the experiment.
Upon creating a short circuit by connecting nodes
and
, a sudden surge of current flows through the short circuit, causing a momentary voltage drop across both diodes. This observation is consistent with recent research findings [
42]. For example, electrical short circuit currents have been experimentally determined to occur within very short time durations, typically in the range of milliseconds, with accompanying short circuit events characterized by current surges and voltage drops. During this transient phase,
, initially forward-biased, experiences a reversal of voltage polarity. When the voltage at point
falls below the cathode potential of
, the diode enters reverse bias. This causes the depletion layer to widen as electrons migrate away from the junction. Simultaneously,
also transitions to reverse bias. The voltage at node
remains higher than the anode potential of
, maintaining the widened depletion layer in
. The widened depletion layers in both diodes play a crucial role in controlling the flow of charge carriers, influencing the energy-circuit’s behavior during transient events. The operational mechanism of this diode configuration was experimentally verified, following the procedure outlined in
Figure 5. Three experiments were conducted, each yielding slightly different pre-short circuit voltage and current values due to potential sensor drifts from repeated experiments. The average pre-short circuit values were
,
, and
for voltage, and
,
, and
for current. During the short circuit event, at comparable time durations and intervals, the voltage and current values were recorded, ranging from
to
and
to
, respectively. These measurements, while influenced by sensor drifts, clearly demonstrate a significant increase in current, over
times the pre-short circuit levels. This substantial current surge is consistent with the characteristic decrease in resistance during a short circuit event. For this analysis, the lowest values of the readings before the short circuit event experiment are considered to establish a baseline. The corresponding voltage and current measurements are also considered for comparative analysis in the subsequent sections. Following this criterion, the voltage and current readings of the baseline chosen experiment before and during the electrical short circuit are provided in
Table 1, which will be referred to as the “baseline-experiment” in the subsequent analysis.
The baseline measurements in
Table 1, taken between nodes
and
of “Circuit Block 2”, demonstrate significant differences in voltage and current values before and after the short circuit event. Before the short circuit, the voltage output remained relatively stable, with minor fluctuations between
and
, while the current fluctuates slightly but remains close to
. This represents the normal operation of the circuit under low resistance conditions, where the 1N5408 power diode operates within its nominal forward voltage drop of approximately
and a forward current of around
, as specified in the diode’s datasheet. Once the short circuit is introduced, a significant change is observed. The voltage output jumps to approximately
, indicating a slight drop in the forward voltage across the diodes, which is characteristic of the diodes entering their surge current state. The current output experiences an extreme increase, consistently hovering around
after the short circuit event. This is far above the diodes' average forward current rating of
but well within their maximum non-repetitive surge current capacity of
. The dramatic rise in current after the short circuit is attributed to the low resistance path created by the short circuit, which significantly reduces the overall resistance in the circuit and allows a higher flow of current. The Modified Ohm’s Law, as employed in this experiment, effectively predicted this behavior. The exponential nature of the short circuit current, derived from Equation 6, becomes evident, with the current escalating as the resistance approaches near-zero values. The 1N5408 power diodes, with their ability to handle up to
of non-repetitive forward current, play a crucial role in safely managing this sudden surge. These results highlight the robustness of the circuit design and the reliability of the 1N5408 power diodes in handling short circuit conditions without damage. The 1N5408 power diode’s exceptional efficiency in maintaining current flow under extreme conditions is further evidenced by its low forward voltage drop of approximately
, observed post-short circuit. During short circuit events, the power output would have surged dramatically. In this experiment, the Standard Ohm’s Law (
) was employed to approximate this power, given the significant short circuit output voltage. The computed average power output during the short circuit was approximately
. While the Standard Ohm's Law may not be strictly applicable to non-ohmic scenarios, it provides a reasonable estimate in this context. However, simulated results (provided in the supplementary materials) indicate that the short circuit output current is influenced by the input voltage. As the input voltage increases, the short circuit voltage and resistance significantly decrease, converging towards non-zero but distinct values. A more sophisticated model is necessary to accurately compute power in such scenarios. To adapt the power output from “Circuit Block 2” for conventional ohmic systems, an additional circuit will be implemented and simulated to develop an ideal model operating under lower voltages, such as the approximate
short circuit output voltage. The Modified Ohm's Law (Equation 6) and its associated power model (Equation 7) are well-suited for theoretical predictions in this low-resistance regime, providing valuable insights into expected practical outcomes. This experiment demonstrates the potential for energy creation and generation in near-zero resistance scenarios. The robustness of the circuit design and the efficiency of the 1N5408 power diodes highlight the feasibility of such applications.
Remark 2 (Power Supply Considerations). The decision to utilize a external power supply was informed by several factors, including the voltage drop across diodes and . This voltage drop, calculated according to Equation 5 as , significantly influences the circuit's overall performance. Additionally, a power supply provides a suitable output voltage for approximate analysis using the Standard Ohm's Law, as demonstrated in the previous power calculations. Given that the energy-circuit’s output voltage from “Circuit Block 2” is limited to , even with an external power input of , the circuit is expected to operate as intended. This theoretical expectation is further explored in a separate paper, while the current paper maintains its focus on the power source application.
Investigation 2. Investigation of Voltage, Current, and Power Fluctuations in Circuit Block 2 Under Short Circuit Conditions. The short circuit current measurement experiment was repeated to investigate the electrical characteristics of “Circuit Block 2”, particularly the behavior of the diode connection under short circuit conditions. Over a three-minute period, measurements were taken every two seconds to observe fluctuations in voltage, current, and power outputs before and during the short circuit event. Three diodes (
,
, and
) were connected in an uncommon parallel configuration to assess their collective performance. Key metrics recorded included voltage drops to approximately
, current surges relatively exceeding
, and power outputs fluctuating between
and
. As shown in
Figure 6, the results indicate that the circuit was not only capable of enduring a sustained short circuit but also generating excess power while effectively protecting the power source from damage.
Figure 6 illustrates the experimental results obtained from “Circuit Block 2” during the short circuit event. It presents the baseline and post-short-circuit experimental results at Node
, providing insight into how voltage, current, and power output transform under short circuit conditions. Prior to the short circuit, the voltage remains relatively stable, averaging around
, indicating a consistent operating state. However, once the short circuit is initiated, the voltage output drops dramatically, averaging
within a narrow range from
to
. This marked reduction in voltage is consistent with short circuit behavior, where the minimal resistance in the short circuit path leads to most of the supply voltage dissipating. Such a drop demonstrates that the circuit is designed to effectively handle high-current conditions without compromising its structural integrity or protective mechanisms, reflecting its efficiency and stability under stress. In terms of current response, the output at Node
initially averages
under standard conditions but undergoes a significant surge to an average of
following the short circuit event. This sharp increase aligns with Ohm’s Law, where a reduction in resistance enables substantially higher current flow. The current remains elevated, ranging between
and
, indicating the circuit’s capability to manage extreme current inflows during a short circuit without displaying erratic behavior or fluctuations. This consistency is crucial for maintaining operational safety, ensuring the power source remains functional without overheating or risking immediate circuit failure, even under extreme conditions. The power output, approximated using the Standard Ohm’s Law as the product of post-short-circuit voltage and current, averages
, representing a notable increase compared to baseline conditions. This elevated power level reflects the transient dynamics between voltage and current, which interact to sustain the high power output. Importantly, the power remains steady, without significant dips, showing that the circuit channels the increased current into useful power output rather than succumbing to energy waste or performance degradation during high-stress events. This efficient conversion and sustained power level demonstrate the circuit’s innovative design, as it effectively manages a potentially destructive short circuit scenario by stabilizing power flow and mitigating risks to the power source. Overall, the ability to sustain elevated current and power output under short circuit conditions underscores the circuit’s advanced design and its capacity to leverage short circuits constructively, maintaining reliable performance across variable conditions.
Implications of the Proposed Energy-Circuit Design. The proposed energy-circuit experimental research has significant implications. The circuit design presented between “Circuit Block 1” and “Circuit Block 2” is the first known experiment to demonstrate how electrical short circuit current can be measured over an extended period within a classical framework. Traditionally, short circuits are considered destructive and often lead to immediate system failure or activation of protection mechanisms [
35,
36]. However, this experiment not only sustains short circuit conditions for a prolonged duration but also enables accurate measurement and analysis of the current flow without destabilizing the power source. This achievement opens up new possibilities for studying high-current, low-voltage phenomena and designing circuits that can withstand extreme electrical conditions. Another significant implication is the violation of the classical law of energy conservation observed in this experiment. The proposed circuit successfully generated excess energy under short circuit conditions, challenging the foundational principle that all power input into an electrical circuit must be consumed or dissipated [
43,
44]. By leveraging an unconventional non-ohmic circuit design, the experiment demonstrated that the circuit could generate power levels far exceeding the input, refuting the notion that electrical systems inherently lose energy during operation. This breakthrough suggests that the energy produced can be harnessed and transformed into a more conventional ohmic output, making it compatible with current electronic and electrical designs. The ability to create excess energy in this way introduces new potential applications in energy systems, where efficiency and power generation are paramount. The higher power output observed during the experiment directly contradicts the traditional view in electric circuit theory that all input power is inevitably consumed or dissipated within the circuit [
45]. Instead, the results suggest that the proposed energy-circuit design can manage and exploit short circuit conditions to generate power that exceeds the input. This has profound implications for the development of energy-efficient circuits that not only protect the power source but also capitalize on what would otherwise be considered destructive electrical events. Lastly, the experimental results highlight the critical role of the combined resistance, as expressed in Equation 9, in contributing to ensuring the forward flow of current. The overall resistance in Equation 9 has also not impeded the circuit from generating excess power output, further refuting the notion of power losses within any circuit aimed at breaking the law of energy conservation. The practical significance of this resistance lies in its contribution to the overall power performance, underscoring the importance of precise resistance management in designing circuits capable of excess energy generation. This advancement demonstrates how innovative circuitry, like the one presented between “Circuit Block 1” and “Circuit Block 2”, can redefine the understanding of energy conservation and power generation in electrical engineering.
Remark 3 (Circuit Protection Mechanism-Power Source). The protective function of “Circuit Block 1” is primarily due to both diodes, and , becoming reverse-biased following a short circuit. This reverse biasing prevents current from flowing in the opposite direction, effectively shielding the power source from potential damage. The depletion layers in and act as barriers, inhibiting the movement of charge carriers and isolating the energy-circuit from any harmful effects induced by the short circuit. This protective mechanism was verified through experimentation with the energy circuit's behavior when “Circuit Block 2” was introduced. Initial results, using a 1N5408 power diode with a input, demonstrated a nearly drop in , the voltage output from “Circuit Block 2”. This significant voltage drop not only confirmed the protective capability of “Circuit Block 1” but also highlighted its effectiveness in managing and analyzing an electrical short circuit.
Remark 4. The proposed energy-circuit configuration (
Figure 4) although uncommon, while innovative in its application of diode characteristics to create a protective mechanism during short circuits, aligns seamlessly with established principles of semiconductor physics and diode behavior [
40,
41]. It adheres to the well-established properties of diodes in forward and reverse bias states, demonstrating a clear understanding of their depletion layer dynamics and the consequent influence on current flow.
2.3.5. Adapting the Energy-Circuit Experimental Results for Ohmic Simulation
The experimental results from the energy-circuit framework, as illustrated in
Figure 5, indicate that significant excess energy was produced compared to the initial energy input. However, these results are incompatible with conventional electronics and engineering circuits that operate at higher voltages than the circuit’s operating currents. The non-ohmic nature of the energy-circuit’s components is the root cause of this discrepancy. To align the generated power with current power systems, the non-ohmic sections must be transformed to produce an ohmic output. The power output from “Circuit Block 2” can be harnessed and converted to an ohmic form while maintaining a relatively constant current. This approach allows for achieving higher power levels through voltage boosting, which is necessary due to the considerable voltage drop during the short circuit. It is also crucial to monitor the power trends between the intended loads and the energy-circuit power generation system developed in
Figure 4. Depending on the power source, some systems may not require prolonged short circuit durations. Therefore, an automated circuit is recommended to control the on-off durations during power creation events (“Circuit Block 5”). In previous experiments, an Arduino-based sensor system was integrated into the energy-circuit to measure the output current. A similar sensing system can be repurposed here to perform the time management task and facilitate seamless power generation. To complete these operations and considering the lower output voltages from “Circuit Block 2”, this section and the subsequent analysis will employ a simulated ideal system based on the Modified Ohm’s Law. Experimental variables will be carefully chosen to mimic real-world scenarios similar to the previously conducted experiments. For instance, consider that after the short circuit happens (this event should be time depended as described in “Circuit Block 5”) the input voltage into “Circuit Block 2” is expected to drop suddenly (as earlier established), to some value by some factor (let this factor be named
and for computational and simulation purposes here, it is set to a lower value;
). The
means that the voltage drop after the short circuit is
of the initial input voltage before the short circuit. So now applying the Standard Ohms Law (
) in this scenario, the voltage across “Circuit Block 2” (referred as
) can be computed as”
. This voltage can be compared with the simulated voltage derived as follows, following the baseline-experiment results in
Table 1.
Voltage Simulation Algorithm. As observed in
Table 1 (baseline experiment results), this simulation algorithm models a scenario where an external small voltage variable DC power supply initializes the voltage at “Circuit Block 1” (
) to approximately
. When the system transitions into a short circuit condition, the voltage output then drops to around
, reflecting the output from “Circuit Block 2” (
) under these circumstances. This simulation algorithm is designed to represent the observed voltage behavior, capturing the significant drop associated with short circuit events.
To establish this framework, we define two transformation variables, and , based on the observed voltage changes:
This variable represents the proportional decrease from the initial at to the short-circuit voltage output of approximately at .
Next, applying this transformation to the input voltage
, we define the function
for the output voltage at
according to Equation 10:
Equation 10 provides a straightforward computation of during simulation, directly scaling the initial input voltage by ccc to simulate the short-circuit output. Here, the algorithm begins with the external DC supply voltage, modulates it through with an output of , and applies the scaling factor to achieve the simulated output of during a short circuit. In implementing Equation 10 within simulation experiments, this approach effectively captures the drastic voltage reduction in response to a short circuit, offering a model that aligns with observed experimental data.
Equation 10 is then applied to compute during the simulation experiemnts.
To this far, we have all the necessary requirements for working out the power output form “Circuit Block 2”. Consider Equation 11.
Equation 11 provides a model for computing the simulated power input to “Circuit Block 3”, which is discussed in the next section.
2.3.6. Circuit Block 3 (Advancing Energy Transformation)
This section introduces “Circuit Block 3”, a crucial component designed to transform the non-ohmic output from “Circuit Block 2” into an ohmic format suitable for standard circuit applications. Building upon the energy transformation process, “Circuit Block 3” introduces the “load component_CB3”, also known as a constant current boost converter. Unlike “Circuit Block 1” and “Circuit Block 2”, which operate in a non-ohmic state, “Circuit Block 3” aims for an ohmic state while maintaining a high and consistent current. To achieve this transition, “Circuit Block 3” leverages the existing resistance from “Circuit Block 1”, denoted as (Equation 8), rather than introducing additional resistive elements (a simplification for simulation purposes). This effective resistance is then incorporated into the analysis of energy conservation to investigate the energy-circuit’s behavior. Within “Circuit Block 3”, the “load component_CB3” plays a key role in achieving the Ohmic state while maintaining consistent short-circuit current. Its primary function is to boost the voltage to its highest achievable level while keeping the current constant. Ideally, this component would be a boost converter circuit. This section explores a simplified design for the “load component_CB3” based on mathematical formulas describing the dynamics of the inductor current () and capacitor voltage () over time. These equations, focusing on the inductor and capacitor as the main components of “Circuit Block 3”, will later be used in simulations to analyze the component’s behavior within the energy-circuit.
The Inductor Current (). The basic formula for the voltage across an inductor is given by;
In Equation 12,
represents the voltage across the inductor,
is the inductance itself, and
signifies the rate of change of the inductor current over time. Equation 12 is a fundamental relationship used in boost converter applications, and it has been adapted for various purposes by [
46,
47]. In the boost converter circuit, during the on-time (
) of the switch, the voltage across the inductor is the difference between the input voltage (
) and the output voltage (
). This is because the inductor is effectively connected to the input during this time. Further, during the on-time (
) of the switching element, the inductor current (
) increases, and during the off-time (
), the inductor discharges through the load. In this case, we consider the scenarios; due to the on-time (
) and due to the off-time (
).
During ON time (). The voltage across the inductor (
) is equal to the difference between the input voltage (
) and the output voltage (
) according to Equation 13.
Now, relating Equation 13 to Equation 12 we obtain Equation 14, which is to be further reduced.
.
During OFF time (). The voltage across the inductor (
