Recent Developments in Power Electronic Inverters for Renewable Energy and Smart Grid Applications
Abstract: Modern power systems that
use renewable energy sources and smart grid technology have been made possible
due to advances in power electronic conversion technology. Power electronic
converters use power semiconductor devices to convert power from one form to
another and thus serve as interfaces in power systems. Developments in power
semiconductor devices and power converter topologies have made possible power
system architectures and capabilities that have improved performance to an
extent that was only dreamt of twenty years ago. This has enabled utilities to
cope with ever-increasing demands for electrical power by commercial and
residential users and to comply with increasingly stringent environmental
regulations that have resulted from concerns about climate change.
The main focus of this presentation will be on recent developments in power electronic inverters that convert DC voltage to AC voltage. Inverters are key building blocks in any modern power system, especially since they are the main interface to the utility grid. Although traditional thyristor-type power converters continue to be used as inverters, there are now a multitude of other options that have found their way in modern power systems.
Bio: Gerry Moschopoulos received the
B.Eng., M.A.Sc., and Ph.D. degrees from Concordia University, Montreal, QC,
Canada, in 1989, 1992, and 1997, respectively, all in electrical engineering.
From 1996 to 1998, he was a Design Engineer in the Advanced Power Systems Division, Nortel Networks, Lachine, QC, Canada. From 1998 to 2000, he was a Postdoctoral Fellow at Concordia University, where he was involved in research in the area of power electronics for telecommunications applications. He is a Professor at the Western University, London, ON, Canada and a Registered Professional Engineer in the province of Ontario.
Dr. Moschopoulos is currently an Associate Editor for the IEEE Transactions on Power Electronics and the IEEE Journal of Emerging and Selected Topics in Power Electronics. He is currently a Guest Editor for the Special Issue on Resonant and Soft-Switching Converters with Wide Bandgap Devices to be published next year in the IEEE Journal of Emerging and Selected Topics in Power Electronics. He has published over 200 papers in journals and conferences. His research interests include AC-DC power converters, DC-DC power converters, switch-mode power supplies for industrial applications, power electronics for renewable energy systems, and inverters.
