There will be a guest lecture on July 1
Discussions on Challenges for Wide Bandgap Power Device for High Power and High Voltage Applications
Dr. Jin Wang, The Ohio State University, USA
The talk will focus on high power applications of Gallium Nitride (GaN) and Silicon Carbide (SiC) devices. It will start with a brief introduction of current development status of high power GaN and SiC devices. Then, common issues that are faced by both GaN and SiC devices including gate drive designs, high dv/dt caused reflective waves, electromagnetic interference, partial discharge, etc. will be discussed. The rest part of the talk will focus on challenges for the implementations of SiC in medium and high voltage applications. Gate drive and auxiliary power supply designs for ≥10 kV rated devices will be discussed in detail. Multiple examples on 3.3 kV, 4.5 kV and 10 kV based circuit building blocks will be included as case study examples.
