Jin Wang received his Ph.D. from Michigan State University, East Lansing, in 2005. From Sept., 2005 to Aug. 2007, he worked at the Ford Motor Company as a Core Power Electronics Engineer. He joined the Ohio State University in 2007 as an Assistant Professor and was promoted to Associate professor in 2013 and full professor in 2017. His research interests include wide bandgap power devices and their applications, high-voltage and high-power converter/inverters, integration of renewable energy sources, and electrification of transportation. Dr. Wang has over 150 peer-reviewed journal and conference publications and 6 patents. Dr. Wang received the IEEE Power Electronics Society Richard M. Bass Young Engineer Award in 2011 and the National Science Foundation’s CAREER Award in 2011. Dr. Wang initiated and served as the General Chair for the 1st IEEE Workshop on Wide Bandgap Power Devices and Applications in 2013.
This educational short course is focused on challenges and opportunities for wide bandgap (WBG) power electronics devices in electric and hybrid electric vehicles (xEVs) based applications. Existing power electronics systems onboard xEVs will be introduced. The design and optimization of traction drive system will be used as an example. Current status of Silicon Carbide (SiC) and Gallium Nitride (GaN) devices will be summarized with examples. Specific challenges and opportunities of implementing state-of-the-art SiC and GaN devices in vehicle power electronics systems will be explained in detail. The intent of this educational short course is to introduce WBG based power electronics systems for xEVs from a practical point of view. It is dedicated to help the audience better understanding how vehicle power electronics are currently designed to meet automotive application requirements and roadblocks for WBGs in automotive applications. The short course should also be of interest to engineers who work on power electronics systems for electrification of other types of transportations.
