Speaker: Jin Wang

Time: Nov. 4, 3:30-5:00pm

Location: Room 220, Building 8


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.


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. 

Dr. Wang received multiple teaching and research awards including the IEEE Power Electronics Society Richard M. Bass Young Engineer Award and the National Science Foundation’s CAREER Award in 2011, Ralph L. Boyer Award for Excellence in Undergraduate Teaching Innovation from the College of Engineering at The Ohio State University in 2012, and the Lumley Research Award of the College of Engineering at The Ohio State University in 2013. Dr. Wang has over 90 peer-reviewed journal and conference publications and two patents. Dr. Wang had been an Associate Editor for IEEE Transactions on Industry Applications from 2008 to 2014.  He initiated and served as the General Chair of the 1st IEEE Workshop on Wide Bandgap Power Devices and Applications in 2013. Currently, Dr. Wang serves as the General Chair for IEEE Future Energy Challenge 2016, the tutorial chair for IEEE Applied Power Electronics Conference 2015, and Associate Editor for IEEE Transactions on Power Electronics and IEEE Journal of Emerging and Selected Topics in Power Electronics (J-ESTPE).
