Curriculum Vitae

Johann W. Kolar received his M.Sc. degree in Industrial Electronics and Control Engineering (with highest honors) and the Ph.D. degree in Electrical Engineering (summa cum laude / promotio sub auspiciis praesidentis rei publicae) from the Vienna University of Technology, Austria, in 1997 and 1999, respectively. Since 1984 he has been working as an independent researcher and international consultant in close collaboration with the Vienna University of Technology, in the fields of power electronics, industrial electronics and high performance drives. He was appointed Assoc. Professor and Head of the Power Electronic Systems Laboratory at the Swiss Federal Institute of Technology (ETH) Zurich on Feb. 1, 2001, and was promoted to the rank of Full Prof. in 2004. Dr. Kolar has proposed numerous novel converter topologies and modulation and control concepts, e.g., the VIENNA Rectifier, the SWISS Rectifier, the Delta-Switch Rectifier, the 1/3 Rectifier, the Isolated Y-Matrix AC-DC Converter, and the three-phase AC-AC Sparse Matrix Converter. He has published over 600+ scientific papers at main international conferences, 280+ papers in international journals, and 4 book chapters. Furthermore, he has filed 190+ patents. He has presented 20+ educational seminars at leading international conferences and has served as IEEE PELS Distinguished Lecturer from 2012 through 2016.

The focus of his current research is on AC-AC and AC-DC converter topologies with low effects on the mains, e.g. for data centers, More-Electric-Aircraft and distributed renewable energy systems, Solid-State Transformers for smart microgrid systems, and Inductive Power Transfer for EV/HEV charging and medical applications). Further main research areas are the realization of ultra-compact and ultra-efficient converter modules employing latest power semiconductor technology (SiC and GaN), Micro Power Electronics and/or Power Supplies on Chip, multi-domain/scale modeling/simulation and multi-objective (Pareto) optimization, as well as ultra-high speed and ultra-light weight drives, bearingless motors, and energy harvesting.

Dr. Kolar has received 11 IEEE Transactions Prize Paper Awards, 16 IEEE Conference Prize Paper Awards, the PCIM Europe Conference Prize Paper Award 2013, the SEMIKRON Innovation Award 2014, the 2014 IEEE Power Electronics Society R. David Middlebrook Achievement Award, the 2016 IEEE PEMC Council Award, and the 2016 IEEE William E. Newell Power Electronics Award. Furthermore, he received the ETH Zurich Golden Owl Award in 2011 and 2017 for Excellence in Teaching and 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 Power Electronics in Europe.

He has graduated 70+ Ph.D. students and has initiated and/or is the founder/co-founder of 4 spin-off companies targeting ultra-high speed drives, multi-domain/level simulation, ultra-compact/efficient converter systems and pulsed power/electronic energy processing.

Dr. Kolar is a Fellow of the IEEE, a Member of the IEEJ, and a member of International Steering Committees and Technical Program Committees of numerous international conferences in the field (e.g. Director of the Power Quality Branch of the International Conference on Power Conversion and Intelligent Motion). He is the founder and chair of the IEEE PELS Austria Chapter (1997-2001) and of the IEEE PELS Switzerland Chapter (2001-2011), and Chairman of the Education Chapter of the European Power Electronics (EPE) Association (since 2001). From 1997 through 2000 he has been serving as Associate Editor of the IEEE Transactions on Industrial Electronics and from 2001 through 2013 as 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.
