Title:

Device Evaluation and Advanced Circuit Prototyping with Wide Bandgap Power Devices

Abstract

Transportation electrification and renewable energy integration are calling for power converters with lower loss and higher power density.  However, in the last three decades, it had become very difficult to derive new and practical circuit topologies.  Fortunately, recent developments of wide bandgap (WBG) power devices provide new opportunities for circuit performance improvement as well as circuit topology identification.  This presentation will focus on device evaluation methods, circuit topologies and circuit design procedures for different types of WBG power devices.  Challenges of device evaluation and circuit design will be identified and discussed in detail.  Tools and multiple examples on statistic measurements, double pulse tests, and switched capacitor based circuit prototyping will be shown in the presentation.

Biography

Jin Wang received a B.S. degree from Xi’an Jiaotong University, in 1998, an M.S. degree from Wuhan University, in 2001, and a Ph.D. from Michigan State University, East Lansing, in 2005, all in electrical engineering. 
From Sept., 2005 to Aug. 2007, he worked at the Ford Motor Company as a Core Power Electronics Engineer and contributed to the traction drive design of the Ford Fusion Hybrid.  Since Sept. 2007, he has been an Assistant Professor in the Department of Electrical and Computer Engineering at The Ohio State University in Columbus, Ohio.  His teaching position is co-sponsored by American Electric Power, Duke/Synergy, and FirstEnergy.  His research interests include high-voltage and high-power converter/inverters, integration of renewable energy sources, and electrification of transportation.
