The “Reliability” of Power Electronics Systems (PESs)

Abstract: The reliability of power electronic systems (PESs) has become a concern with the increased penetrations of the internet of things (IoT) enabling cyber-physical systems (CPSs) into the energy grid and electrified transportation. Department of Energy (DoE) predicts that 80% of U.S. electricity will flow through PESs by 2030. This PESs-enabled power system allows bi-direction energy flows between energy storages and loads, integrating renewable/alternative energy sources and electrified transportations into a grid and their autonomous operations. As an essential element of future energy systems, the reliability and security analysis of PESs are an emerging need. To address these issues, this talk will provide a semi in-depth discussion on (i) the degradation of wide bandgap (WBG) power switches, (ii) new common-mode EMI modelings, (iii) the degradation of electric machines systems, and other ongoing projects (cybersecurity and ultrahigh-speed machine (> half-million RPM)). The expected level of the intended audience is with entry and intermediate backgrounds in electrical and mechanical engineering.

Dr. Seungdeog Choi is an associate professor at Mississippi State University since 2018. He received the B.S. degree from Chung-Ang University, Seoul, South Korea, in 2004, the M.S. degree from Seoul National University, Seoul, South Korea, in 2006, and the Ph.D. degree in electric power and power electronics program from Texas A&M University, College Station, TX, USA, in 2010. From 2006 to 2007. He was a research engineer in LG Electronics, Seoul, South Korea. From 2009 to 2012, he was a Research Engineer with Toshiba International Corporation, Houston, TX, USA. He was an Assistant Professor at The University of Akron, Akron, OH, the USA from 2012~2018. He is currently serving as associate editor in IEEE Transactions on Industrial Electronics, editor in IEEE Transactions on Energy Conversion, and guest editor on a special topic on IEEE Transactions on Energy Conversion from 2018. He serves as a reviewer, session chair, topic chair, track chair, and publication chair in various IEEE conferences. The keyword of his research is “Reliability, Efficiency, and Power Density.” He has published more than 130 articles, including more than 10 U.S. patents in the area.
