Abstract
The article presents the results of tests related to failure analysis and finding ways to diagnose used semiconductor elements, among other, in power electronics converter systems on vessels and offshore facilities (drilling and production rigs, wind turbines). Diagnostic relationships were found between the temperature change in the above systems and the signals generated in form of elastic waves of acoustic emission. The authors confirmed the influence of the transistor's working temperature on its amplitude-frequency spectrum of acoustic emission signal emitted. The range of 'safe temperatures' was considered which we mean a temperatures that does not directly affect the damage of the component.
