Biography

A visionary leader in the field of power electronics, Johann W. Kolar has a distinguished record of providing industry with key innovations for ensuring high power quality and saving energy. He has driven advances in three-phase pulse-width modulation rectifier and matrix converter technology, including the Vienna Rectifier and the Sparse Matrix Converter, over the past two decades. Offering outstanding performance concerning efficiency, power density, harmonic distortions, and costs, the Vienna Rectifier is widely employed for power supply of data centers and industry processes, as well as actuators of electric aircraft. Furthermore, Kolar has spearheaded the introduction of multi-objective optimization as a fundamentally new research approach into power electronics and has proposed a revolutionary new approach for education in power electronics that is used today in academia and industry all over the world.

An IEEE Fellow, Kolar is a full professor and chair of the Power Electronic Systems Laboratory at ETH Zurich, Zurich, Switzerland.
