Abstract

A design procedure is proposed for the electromagnetic compatibility (EMC) filters to be included in a three-phase/-level PWM rectifier unit in order to fulfill EMC requirements related to conducted emissions. An analytical volumetric optimization is performed considering constraints given by electrical safety, power factor and damping of resonances. The procedure avoids the necessity of applying numerical optimization allowing the analytical calculation of the total filter volume as function of rated power and switching frequency. The experimental verification of the proposed procedure is presented through con- ducted emissions (CE) measurements in the designed system.

received his Ph.D. degree (summa cum laude / promotio sub auspiciis praesidentis rei publicae) from the University of Technology Vienna, Austria. Since 1984 he has been working as an independent international consultant in close collaboration with the University of Technology Vienna, in the fields of power electronics, industrial electronics and high performance drives. He has proposed numerous novel PWM converter topologies, and modulation and control concepts, e.g., the VIENNA Rectifier and the Three-Phase AC-AC Sparse Matrix Converter. Dr. Kolar has published over 250 scientific papers in international journals and conference proceedings and has filed more than 70 patents. He was appointed Professor and Head of the Power Electronic Systems Laboratory at the Swiss Federal Institute of Technology (ETH) Zurich on Feb. 1, 2001. The focus of his current research is on AC-AC and AC-DC converter topologies with low effects on the mains, e.g. for power supply of telecommunication systems, More-Electric-Aircraft and distributed power systems in connection with fuel cells. Further main areas of research are the realization of ultra-compact intelligent converter modules employing latest power semiconductor technology (SiC), novel concepts for cooling and EMI filtering, multi-domain/multi-scale modeling and simulation, pulsed power, bearingless motors, and Power MEMS. He received the Best Transactions Paper Award of the IEEE Industrial Electronics Society in 2005. He also received an Erskine Fellowship from the University of Canterbury, New Zealand, in 2003. In 2006, the European Power Supplies Manufacturers Association (EPSMA) awarded the Power Electronics Systems Laboratory of ETH Zurich as the leading academic research institution in Europe. Dr. Kolar is a Member of the IEEE and a Member of the IEEJ and of Technical Program Committees of numerous international conferences in the field (e.g. Director of the Power Quality Branch of the International Conference on Power Con[1]version and Intelligent Motion). From 1997 through 2000 he has been serving as an Associate Editor of the IEEE Transactions on Industrial Electronics and since 2001 as an Associate Editor of the IEEE Transactions on Power Electronics. Since 2002 he also is an Associate Editor of the Journal of Power Electronics of the Korean Institute of Power Electronics and a member of the Editorial Advisory Board of the IEEJ Transactions on Electrical and Electronic Engineering.
