Yongheng Yang received the B.Eng. degree in Electrical Engineering and Automation in 2009 from Northwestern Polytechnical University, China and the Ph.D. degree in Electrical Engineering in 2014 from Aalborg University, Denmark. He was a postgraduate with Southeast University, China, from 2009 to 2011. In 2013, he was a Visiting Scholar at Texas A&M University, USA. Since 2014, he has been with the Department of Energy Technology, Aalborg University, where currently he is an Assistant Professor. His research interests are focused on grid integration of renewable energy systems, power converter design, analysis and control, harmonics identification and mitigation, and reliability in power electronics. Dr. Yang has published more than 100 technical papers and co-authored a book - Periodic Control of Power Electronic Converters (London, UK: IET, 2017). Dr. Yang is a Member of the IEEE Power Electronics Society (PELS) Students and Young Professionals Committee, where he serves as theInternational Strategy Chair and responsible for the IEEE PELS Students and Young Professionals Activities. He served as a Guest Associate Editor of IEEE Journal of Emerging and Selected Topics in Power Electronics and has also been invited as a Guest Editor of Applied Sciences.Frede Blaabjerg was with ABB-Scandia, Randers, Denmark, from 1987 to 1988. From 1988 to 1992, he was a Ph.D. Student with Aalborg University, Aalborg, Denmark. He became an Assistant Professor in 1992, Associate Professor in 1996, and Full Professor of power electronics and drives in 1998. His current research interests include power electronics and its applications such as in wind turbines, PV systems, reliability, harmonics and adjustable speed drives. He has received 17 IEEE Prize Paper Awards, the IEEE PELS Distinguished Service Award in 2009, the EPE-PEMC Council Award in 2010, the IEEE William E. Newell Power Electronics Award 2014 and the Villum Kann Rasmussen Research Award 2014. He was an Editor-in-Chief of
