초록

Recently, SRMs are used in automobiles for power assistant steering, accessory motion control and traction drives. Especially in the motion control and traction drives, safety and efficiency are of paramount important. The paper describes the essential elements, faced in designing and constructing drive circuits for a switched reluctance motor for automobiles. These converters will be referred to as energy efficient C-dump converter and modified C-dump converter Energy efficient C-dump converter topology eliminate all the disadvantages of the C-dump converter without sacrificing its attractive features, and also provide some additional advantages that have lower number of power devices, full regenerative capability, free-wheeling in chopping or PWM mode, simple control strategy, and faster demagnetization during commutation. The experiments are peformed to verify the capability of proposed control method on 6/4 salient type SRM.
