Professor PA Mawby BSc. PhD (Leeds) C.Eng. FIET SMIEEE FinstP Chair of Power Electronic, Applications and Technology in Energy Research, Electrical and Electronics Division, School of Engineering, University of Warwick.

The Power Electronic Applications and Technology in Energy Research, PEATER group was founded in 2005 by Professor Philip Mawby, to establish a world-class centre for research into power electronics, power semiconductor devices and applications in power systems and power conversion.

The centre carries out work in electrical energy conversion, from the very small power (mW) levels to very high power levels (MW). This technology centres on the developments in semiconductor switching devices. The developments in MOSFET and IGBT technologies have paved the way for new applications such as Hybrid vehicles, Electric Aircraft, Electric Ship propulsion, Wind Turbines as well as the revolution in mobile phone and computing devices, were energy management is critical to all these applications.

Johann W. Kolar
Chair of Power Electronics and Electrometrology ETL H 22 Physikstrasse 3 8092 Zürich

Johann W. Kolar has been Associate Professor (since February 2001) and Full Professor at the Swiss Federal Institute of Technology (ETH) Zurich since 1 October 2004. He is the Head of the Power Electronics and Electrometrology Laboratory.

Johann W. Kolar was born in Austria on July 15, 1959. He studied industrial electronics at the University of Technology Vienna, Austria, and received his Ph.D. degree (summa cum laude) in 1998. Since 1984 he has been with the University of Technology in Vienna, and has been teaching and working in research in close collaboration with the industry in the fields of high performance drives, high frequency inverter systems for process technology and uninterruptible power supplies. He has proposed numerous novel converter topologies, e.g., the VIENNA Rectifier concept. Johann W. Kolar has published over 100 scientific papers in international journals and conference proceedings and has filed 45 patents.

The focus of his current research is on novel converter topologies with low effects on the mains, e.g. for power supply of telecommunication systems and distributed power systems in connection with fuel cells. A further main area of research is the realization of ultra-compact intelligent converter modules employing latest power semiconductor technology (SiC) and novel concepts for cooling and EMC filtering. Here, apart from a detailed theoretical analysis, also the practical realization in accordance with industrial requirements is the main goal.
