Andreas Steimel, born 1947, studied Electrical Engineering at the Technical University Darmstadt from 1967 to 1972 and obtained the degree of Dr.-Ing. from the same university in 1977. From 1977 to 1990 he was first with the Central Electronic Development Division and later with the Traction Division of Brown Boveri & Cie. (later Asea Brown Boveri) in Mannheim, being responsible for traction converters and power systems of main-line locomotives.
In May 1990 he has been appointed Professor for Electrical Power Engineering at the Ruhr-University Bochum and since 1994 he has been Head of the Chair for Electric Power Engineering and Power Electronics. His main research interests are in power electronics and AC drive control, with the focus on traction applications and Power Quality. He supervised 16 PhD's up to now.
Prof. Steimel is Senior Member of IEEE, member of VDE and was Chairman of Section A2 "Railways and Vehicles with Electric Drives" in the Energy Technology Group (ETG) of VDE from 1998-2006. He is Member of the Board of Editors of the scientific journals European Transactions on Electrical Power (ETEP) and Elektrische Bahnen and was Deputy Speaker of Section Electrical Engineering (408) of the German Research Council (DFG). He authored and coauthored over 30 journal papers and book contributions, 125 conference papers and is author of the book "Electric Traction - Motion Power and Energy Supply". In 2011 he was awarded the title Doctor honoris causa by the University Stefan cel Mare Suceava, Romania.
