Biography of Speakers
Frede Blaabjerg (F’03) is a Professor with the Department of Energy Technology and the Director of
Center of Reliable Power Electronics (CORPE), Aalborg University, Denmark. He has intensive research
work on power electronics and its applications in motor drives, wind turbines, PV systems, harmonics, and
the reliability of power electronic systems. He has held more than 300 lectures national and international,
most of them in the last decade are invited and as keynotes at conferences, covering various topics on
power electronics, including the reliability. He was a Distinguished Lecturer for the IEEE Power Electronics
Society from 2005 to 2007 and for the IEEE Industry Applications Society from 2010 to 2011. He has
contributed more than 800 journal and conference papers, many of which in the last four years are relevant
to the reliability of power electronic components, converters and systems. Dr. Blaabjerg received the IEEE
William E. Newell Power Electronics Award in 2014, the IEEE PELS Distinguished Service Award in 2009,
the Outstanding Young Power Electronics Engineer Award in 1998, and 15 IEEE Prize Paper Awards. He
served the Editor-in-Chief of the IEEE Transactions on Power Electronics from 2006 to 2012.
Xiongfei Wang is an Associate Professor with the Department of Energy Technology, Aalborg University,
Denmark. His research interests include small-signal modeling of power electronic converters, harmonics
analysis and control, passive and active filters, and stability of power-electronics-based power systems. He
has contributed 40 journal papers on the stability and control of grid-connected power electronic systems.
He is the co-lecture for the Industrial/PhD course on Modeling and Control of Voltage Source Converters at
Aalborg University, Denmark. Dr. Wang received his Ph.D. degree from Aalborg University, Denmark. He
serves as the Associate Editor for IEEE Transactions on Industry Applications, and the Associate Editor for
IEEE Journal of Emerging and Selected Topics in Power Electronics. He received IEEE Power Electronics
Transactions prize paper award in 2014.
