| 摘 要： | 9kW双凸极永磁电机功率控制器的主电路采用三相桥式变换器。与一般的三相桥式变换器相比，本文的三相桥式变换器因受到电机反电势、霍尔传感器位置信号及特定开关工作方式等因素的影响，工作情况复杂，工作原理也有较大差异。文中阐述了基于理想工作情况下的双凸极永磁电机三相桥式功率变换器的工作原理，给出了在电机反电势不对称、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，实验证明了该变换器分析的正确性。

| Abstract: | The three-phase bridge inverter is used as the converter topology in the power controller for a 9 kW doubly salient permanent magnet (DSPM) motor. Compared with common three-phase bridge inverters, the proposed inverter works under more complicated conditions with different principles for special winding back EMFs, position signals of hall sensors, and the given mode of switches. The ideal steady driving principles of the inverter for the motor are given. The working state with asymmetric winding back EMFs, inaccurate position signals of hall sensors, and the changing input voltage is analyzed. Finally, experimental results vertify that the given analysis is correct. |
