本研究提出了一种新的开关磁阻电动机驱动电源转换器的配置。该系统允许通过在电机操作期间实现绕组连接的重新配置来减少电机绕组中的换向过程对整体电机性能的不利影响。较短的换相时间，这是系统的主要特点，增加了电机的平均转矩，特别是在高转速的操作范围。该系统在一个标准的开关磁阻电机驱动器的应用结果在扩展的操作范围与恒定的转矩和机械功率多达两倍。将该系统驱动的电机的机电特性与标准半桥变换器驱动的电机的机电特性进行了比较。
This study presents a new configuration of power converter for switched reluctance motor drives. The system allows reduction of the detrimental impact of the commutation processes in motor winding on overall motor performance through enabling reconfiguration of windings connection during operation of motor. Shorter time of commutation, which is the main characteristic of the system, increases the motor average torque particularly in range of operation with high rotational speed. Application of the system in a standard switched reluctance motor-based drive results in extension of range of operation with constant torque and mechanical power as much as two times. The electromechanical characteristics of motor driven from the system are compared with those of the same motor driven from a standard half-bridge converter.
