EMI Suppression Skills for Power Electronic System Design

The IEEE Rock River Valley Section (RRVS) EMC and PELS Chapters are pleased to sponsor the 4th EMC Educational Seminar in Rockford, Illinois. Our goal is to provide regional affordable seminars that provide critical educational value to engineers working in the diversified industries in the region. This seminar focuses on the issues Engineers need to know about EMI prevention and management techniques when designing modern day electronic systems. The evolution of high speed switching devices such as MOSFETs and IGBTs, high speed digital control, electromagnetics and capacitors has paved the way for low cost, high density power electronics. However, like high speed digital circuits, these switched power circuits are capable of generating significant conducted or radiated interference. The thrust of this seminar is to ensure the Electro Magnetic Compatibility of the power circuits in designs.


Dr. Shuo Wang received the Ph.D. degree from Virginia Tech, Blacksburg, VA, in 2005. He has been an associate professor with the Department of Electrical and Computer Engineering, University of Florida, Gainesville, FL, since 2015. From 2010 to 2014, he was with University of Texas at San Antonio, TX, first as an assistant professor and later as an associate professor. From 2009 to 2010, he was a senior design engineer in GE Aviation Systems, OH. From 2005 to 2009, he was a research assistant professor at Virginia Tech.


Dr. Shuo Wang has published more than one hundred IEEE journal and conference papers and holds 7 US patents. He received the Best Transaction Paper Award from the IEEE Power Electronics Society in 2006 and two William M. Portnoy Awards for the papers published in the IEEE Industry Applications Society in 2004 and 2012, respectively. In 2012, he received the prestigious National Science Foundation CAREER Award. He is an Associate Editor for the IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS and a technical program Co-Chair for IEEE 2014 International Electric Vehicle Conference.
