Four Quadrants Operation Analysis of 12/8 SRM for Electric Vehicle

设计了5kW电动车辆用的12/8极开关磁阻电机(Switched Reluctance Motor,简称SRM)驱动系统,同时结合电动车辆驱动要求,确定了四象限运行的控制逻辑;根据SRM各种控制方案,实现了电流斩波、角度位置、电压PWM斩波及单脉冲控制相结合的综合控制方案。经过实验验证,系统能够在四象限稳定运行并可靠切换,达到了电动车辆各种运行状态的要求。

This paper deals with 5kW 12/8 Switched Reluctance Motor （SRM） drive system for Electric Vehicle （EV）.Considering the characteristics of EV,the control logic for four-quadrant operation is ascertained.According to the control schemes of SRM drives,an integrated scheme is designed,including Current Chopping Control （CCC）,Angular Position Control （APC）,Voltage PWM Control （VPWMC） and Single Pulse Control （SPC）.Proved by experiments,the motor runs reliably in four quadrants and satisfies the operating requirements of EV.
