Beyond Efficiency and Power Density - Towards Reliable Power Electronics

Speaker: Huai Wang

Time: May 27, 3:00pm - 4:30pm.

Location: Room 306, Teaching Center


The performance of power electronic converters, especially in terms of efficiency and power density, has been continuously improved by the intensive research and advancement in circuit topologies, control schemes, semiconductors, passive components, and system integration technologies. With the increasing use of power electronics, the automotive and aerospace industries have brought stringent reliability constraints because of safety requirements. The renewable energy sector is also following the same trend to more reliable power electronic systems to reduce the cost of failure. 

This seminar will revisit the design and control of power electronic converters from a reliability perspective. A few application examples from LED lighting systems, to PV inverters, and wind power converters will be given. The ongoing paradigm shifts in the state-of-the-art research and opportunities will also be discussed. Finally, the seminar will have a brief introduction of the research activities at the Center of Reliable Power Electronics (CORPE) of Aalborg University, Denmark.


Huai Wang is currently an Associate Professor and a work package leader with the Center of Reliable Power Electronics (CORPE), Aalborg University, Denmark. His current research interests include the reliability of power electronic systems, reliability of capacitors and IGBT modules, multi-physics modeling and virtual prototyping, DC-DC converters, inverters for motor drive, PV and wind power applications, and emerging power electronic applications.

Prof. Wang has co-edited a book on reliability of power electronic converter systems in 2015, filed 4 patents, and contributed more than 90 SCI/EI papers. He received the PhD degree from City University of Hong Kong, Hong Kong, China, in 2012, and the Bachelor degree from Huazhong University of Science and Technology, Wuhan, China, in 2007. He was a visiting scientist with the ETH Zurich, Switzerland in 2014 and with the Massachusetts Institute of Technology (MIT), Cambridge, MA, USA, in 2013. He was with the ABB Corporate Research Center, Baden, Switzerland, in 2009. He serves the Guest Editor-in-Chief of IEEE JESTPE special issue on power electronics for energy efficient buildings and an Associate Editor of IEEE Transactions on Power Electronics.
