New class of dual voltage converters for switched reluctance drives

An entirely new class of dual voltage switched reluctance drives is presented. New power converter circuits are introduced, which allow a switched reluctance motor to operate from either an AC mains or a battery supply, with minimal extra power semiconductor components and no extra transformer. Battery charging is achieved without additional components. These converters offer considerable cost savings and flexibility when compared with conventional solutions to the problem of creating a system that can operate from both AC mains supply and battery
