300 kW Switched Reluctance Generator for Hybrid Vehicle Applications 2002-01-1087
The switched reluctance generator, because of its simple and robust structure, is attractive as an auxiliary power unit (APU) in lightweight, high-speed and high power military, and other types of vehicles. In this paper, investigation and design analysis of a 300 kW switched reluctance generator is presented. Five different designs of the machine are evaluated to provide 300 kW at 30,000 rpm, 60,000 rpm, and at 100,000 rpm. The different designs are compared in terms of size, weight, efficiency, and torque. Analyses of the mechanical stress and critical speeds are also presented. Recommendations are presented for the selection of the best design methodology for APU application in Hybrid vehicles.
