摘　　要：以四相8/6极、5.5kW开关磁阻电动机为研究对象,设计了一种结构简单、性能可靠的开关磁阻电机调速系统。系统采用TMS320F240为主控单元。详细介绍了系统的结构组成和工作原理,设计了一种新型功率变换电路,保留了桥式电路的优点,且所用开关器件数目比半桥控制的还要少。实验表明:系统不仅结构简单,而且调速性能优良。A switched reluctance drive system which has simple structure and reliable capability is presented. It is designed based on 4 phase, 8/6 pole and 5.5 kW switched reluctance motor. It adopts TMS320F240 as main controlling unit, introduces the structure and principle of system in detail, and develops a new power converter circuit. It reserves the advantage of bridge circuit, and has less on-off components than half bridge＇ s. The running test proves the system has simple structure and superior performance.
