摘　　要：详细阐述基于理想工作情况下的双凸极永磁电动机三相桥式功率变换器的工作原理,给出在电动机反电势不对称、霍尔传感器位置信号不准确以及输入电压变化等情况下功率变换器的工作情况的分析,并通过实验证明了分析的正确性。The three-phase inverter is used as the converter topology in power controller for 9kW doubly salient permanent magnet motor. Compared to common three-phase inverter, the inverter works in more complicated modes for the special winding back EMFs and the use of hall sensors for detecting rotor position. The ideal steady operating principles of the inverter for the motor are first detailed, and then the analyses are given on the asymmetry of three winding back EMFs, inaccuracy of hall sensor positions, and change of input voltage, The experimental results testify the analysis given is correct.
