Kai Kriegel, Industrial Application of Wide Bandgap Semiconductors Devices

The lecture will provide an overview of current silicon power electronics devices and the properties and existing problems. The new WBG materials siliconcarbide (SiC) and Galliumnitride (GaN) and the power electronics devices from these materials will be introduced and their main properties are discussed. Then the lecture will give a wide overview of the different application fields e.g. industrial, automotive, aerospace and energy conversion. The lecture is as well on the special challenges on packaging for high temperature, high power density and high reliability.

Dr. Kai Kriegel received a degree in electrical engineering and a degree in business administration from the RWTH Aachen University. He was working at the Institute of Ferrous Metallurgy of the RWTH Aachen University and received the Dr.-Ing. degree in 2001. Since 2001 he has been working at Siemens Corporate Technology in Munich as project manager on different R&D projects in the field of power electronics and drive technology, especially for automotive and aerospace applications.
