4. Result and Discussion
When AI is introduced into WPT systems, it dramatically improves efficiency, range, and reliability of Wireless Power Transfer. In our set of experiments we, primarily employed neural networks to learn the power flow optimization and noticed that the AI approach helped to increase the power transfer efficiency by up to 25% to the conventional methods [
1]. In particular, the efficiency of newly designed AI-enhanced WPT system was kept almost 90% for 10 cm distance with 0-degree angle and with minimal increase in temperature. Power transfer control in WPT systems was examined using various AI algorithms in terms of performance. Neural networks slightly surpassed the decision trees and the random forests based on the highest optimization accuracy of 92.3 % and the maximum power loss reduction [
2] of 25% (
Table 3). Such findings confirm the capacity of the neural networks in solving special non-linear optimization issues related to the WPT systems. Considering the experiments conducted in the present work, particular attention should be paid to the WPT system configuration. Some of the major variables of the core transformer were number of turns on primary and secondary coils, coil diameter, frequency of use, and voltage of the power supply. It is worth examining the description of these parameters in more detail; they are listed in
Table 6. The correct configuration implied the proper distribution of the currents and reduced the losses into the system [
3,
4]. In this context, the differences in efficiency of the compared WPT technologies with AI integration, as well as the distance ranges recorded in
Table 7, where resonant WPT systems set the highest efficiency of 90%, are noted. On the other hand, for technologies like microwave and laser which were other long range technologies, the efficiency was relatively low. This means that for applications promising high efficiency over medium distances [
5], resonant WPT systems need to be used. AI was proved helpful in forecasting the maintenance in WPT systems.
Table 8 shows the authors predictive models provided accuracies higher than 88% on different assignments including coil alignment and power supply sustenance. This high prediction accuracy dramatically decreases the percentage of false positive and negative cases [
6,
7], which in turn increases the dependability and availability of WPT systems. In addition, the findings of the experiment supported the promotion of the use of artificial intelligence. Figures and tables present below depict that how AI-enhanced WPT system is efficient and has minimal temperature variation under different circumstances, as mentioned in
Table 4. As a result, the neural network-based system preserved the stable transmission performance in different alignments and distances, which proved that the AI method was feasible in practical WPT applications [

9].
