摘要
不对称半桥是开关磁阻电机常用的驱动功率回路,其主要缺点是电机与驱动电源的主回路连接线过多。现将三相开关磁阻电机的三相绕组采用星形连接,由三相逆变桥对其供电,并以51单片机为控制器核心,采用720°电角度一周期的对称不均匀励磁方式。实验证明,该控制方式可在减少连接线的前提下,使三相开关磁阻电机在出力方面达到与不对称半桥驱动方式等同的运行效果。
Asymmetry half bridge was acommon power supply for Switched Reluctance Motor （SRM） ,its main weakness was excessive lines between SRM and supply power.This paper adopted star type conjunction on three phase SRM,supplied with three phase invertion bridges.51 MCU was the core for controller,it matched with symmetry and uneven excitation mode with 720°electric angle a cycle.Experiment Validated,that the control mode can get equal movement result compared with asymmetry half bridge mode at outputing power aspect and resolve the problem of excessive lines between SRM and supply power.
