摘　　要：采用只有 6只主开关器件的四相功率变换器 ,在以80 98单片机为控制核心的 75 0WSR电机直接数字控制系统设计中 ,引入两步换相控制策略 ,在电压PWM和APC两种工况下 。This paper describes the main consideration in the design of the direct digital control system for a switched reluctance motor (SRM).The paper addresses the problem of implementation of the new commutation strategy introduced by the predecessors for the reduction vibration and acoustic noise in SRM .A new type power converter circuit is designed to make efficient use of both hardware and software. Some experiment validation are given based on a 750W laboratory prototype SRM drive with both voltage PWM control mode and angular position control mode.
