Thomas A. Lipo
An international authority on the design and analysis of electric machines and power electronics drives for over 40 years, Thomas A. Lipo’s innovative contributions have advanced the state of the art and improved the efficiency and reliability of motors and drives. Prof. Lipo began his pioneering work in 1968 with the analysis, simulation, and control of early alternating-current motor drives, impacting electric traction control for subway cars and open pit mining equipment, among other applications. He has pioneered or improved upon electrical machine topologies, including flux switched machines, high torque vernier machines, axial flux permanent magnet machines, brushless doubly fed reluctance machines, open winding machines, and double air gap machines. He also pioneered modern, multiphase fault-tolerant machines, demonstrating that a new family of five-phase induction and synchronous reluctance motors could provide more torque and higher robustness compared to traditional three-phase motors. Prof. Lipo’s work with his students on permanent magnet motors has provided a key element for the design of traction applications in hybrid and electric vehicles, known as the “characteristic current.” Also among his trend-setting research that has helped move power technology from concept to practical applications, Prof. Lipo and his students were the first to investigate methods of eliminating the effects of input voltage unbalance on motor drives. This work has been widely referenced and used in many commercial applications. In 1980, Prof. Lipo cofounded the Wisconsin Electric Machines and Power Electronics Consortium at the University of Wisconsin, WI, USA, which has become an internationally renowned collaborative effort of industry sponsors, professors, and students in the research and development of new power electronics technologies.
An IEEE Life Fellow and member of the US National Academy of Engineering and the UK Royal Academy of Engineering, Prof. Lipo is an Emeritus Professor with Department of Electrical and Computer Engineering at the University of Wisconsin, Madison, WI, USA.
