Welcome to the Professorship of Power Electronics!

   

 

The research focus of the Professorship of Power Electronics is the investigation of robustness and reliability of power semiconductor devices. The main focus is on the topics of overload capability (short circuit, surge current, avalanche) and power cycling ruggedness. This includes the consideration of the semiconductor materials Si, SiC and GaN. Semiconductor and thermomechanical simulations on FEM basis are being used to examine internal physical processes further in detail.
Until 2020 the professorship was headed by Prof. Dr.-Ing. Prof. h.c. Josef Lutz. After that Prof. Dr.-Ing. Thomas Basler took over.

At the PCIM Europe, the user-oriented seminars and tutorials are an optimal platform for direct exchange. The full day totorial of Josef Lutz is on Reliability and Lifetime Estimation of Si and Wide Bandgap Power Devices and Packages. Here is the link to the tutorial May 8th:

There are much new trends in packaging, driven by E-car drive inverters: Molded packages, advanced insulation sheets, new cooling methods - single side/double side cooling, etc. The tutorial will now address the new solutions for heat flux. Further, outdoor application are challenging the reliability under high humidity. New suggested test methods will also be included. The tutorial will be widely updated compared to former tutorials of Josef Lutz. Here's the link for more information and to get your ticket: Ticket
