Prof. Werner Hugo Wölfle was born in Bad Schussenried, Germany. He graduated from the University of Stuttgart in Germany in 1981 as a Diplom-Ingenieur in Electrical Engineering. He completed a PhD degree in Electrical Engineering at the National University of Ireland, Galway in 2003.
He was a lecturer and lead researcher from 1981 to 1982 at the "Institut for Leistungselektronik und Anlagentechnik" at the University of Stuttgart, where he developed the first 20kW switch mode power converter with high voltage bipolar transistor technology for thin blade welding applications.
He worked from 1982 to 1985 for Dornier Systems GmbH, where he adapted this technology for space applications. He was power systems and project manager for the high power conversion and control units for two payload experiments (MEDEA) for the SPACELAB D1 Mission of the European Space Agency (ESA) and he also was the leading design engineer for the primary satellite power system for the X-Ray Observatory Satellite (ROSAT).
From 1986 to 1989 he worked as a Research and Development Manager of industrial AC and DC power converters with Riester GmbH. Since 1989 he is Managing Director of Convertec Ltd. in Ireland. Convertec develops high reliability power converters for industrial applications and renewable energy systems.
