1306 IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS, VOL. 38, NO. 5, SEPTEMBER/OCTOBER 2002 Thomas A. Lipo (Mâ64âSMâ71âFâ87) is a native of Milwaukee, WI. He received the B.E.E. and M.S.E.E. degrees from Marquette University, Milwaukee, WI, in 1962 and 1964, respectively, and the Ph.D. degree in electrical engineering from the University of Wisconsin, Madison, in 1968. From 1969 to 1979, he was an Electrical Engineer in the Power Electronics Laboratory of Corporate Research and Development, General Electric Company, Schenectady, NY. He became a Professor of Electrical Engineering at Purdue University, West Lafayette, IN, in 1979 and, in 1981, he joined the University of Wisconsin, Madison, in the same capacity. He is presently the W.W. Grainger Professor for Power Electronics and Electrical Machines, Co-Director of the Wisconsin Electric Machines and Power Electronics Consortium, and Director of the Wisconsin Power Electronics Research Center. Dr. Lipo has received the Outstanding Achievement Award from the IEEE Industry Applications Society, the William E. Newell Field Award from the IEEE Power Electronics Society, and the 1995 Nicola Tesla IEEE Field Award from the IEEE Power Engineering Society for his work. Over the past 30 years, he has served the IEEE in numerous capacities, including President of the IEEE Industry Applications Society. Giri Venkataramanan studied electrical engineering at the Government College of Technology, Coimbatore, India, California Institute of Technology, Pasadena, and the University of Wisconsin, Madison. After teaching electrical engineering at Montana State University, Bozeman, he returned to the University of Wisconsin, Madison, as a faculty member in 1999, where he continues to direct research in various areas of electronic power conversion as an Associate Director of the Wisconsin Electric Machines and Power Electronics Consortium (WEMPEC). He is the holder of four U.S. patents and has authored a number of published technical papers. Steffen Bernet (Mâ97) was born in Ilmenau, Germany, in 1963. He received the M.S. degree from the Technical University of Dresden, Dresden, Germany, in 1990 and the Ph.D. degree from the Technical University of Ilmenau, Ilmenau, Germany, in 1995, both in electrical engineering. His doctoral thesis contained the investigation of power semiconductors in soft switching converters. He was a Development Engineer with the Department of Private Communication Systems, Siemens, from 1994 to 1995. During 1995 and 1996, he was a Post-Doctoral Researcher in the Electrical and Computer Engineering Department, University of Wisconsin, Madison. In 1996, he joined ABB Corporate Research, Heidelberg, Germany, where he led several power electronics research projects and developed various novel high-power converters including resonant snubber based current source converters, matrix converters, and three-level voltage-source inverters. He led the Electrical Drive Systems Group, ABB Corporate Research, Heidelberg, from 1998 to 2001. In 1999, he was appointed Subprogram Manager for Power Electronics Systems, ABB Corporate Research Worldwide. In 2001, he joined the Technical University of Berlin, Berlin, Germany, as a Professor of Power Electronics. His main research areas are high-power converter topologies, power semiconductors, and motor drives.
