The Fraunhofer Institute for Solar Energy Systems has reached a new efficiency milestone. Its III-V germanium solar module achieved 34.4%, a step forward for a technology that could eventually squeeze ...

Abstract: Partial discharge (PD) in the high voltage packaging insulation under square pulse with a high slew rate (SR or dV/dt) is one of the main causes of the power module failure, especially for ...

Abstract: Partial discharge (PD) is an important characterization parameter of the reliability state of the insulation system, and it is also one of the reasons why the insulation structure fails for ...
