摘　　要：在对六相电压源逆变器矢量控制的分析基础上,结合六相系统电压矢量开关模式的特点,通过对两个零矢量在开关周期中的合理分配,提出新的适用于六相电压源逆变器空间矢量控制方法。该方法在保证输出性能的前提下可以有效地降低开关损耗。仿真结果验证了该方法的有效性。Based on the vector control analysis of a six-phase voltage source inverter and combined with the characteristics of the six-phase system voltage vector switch mode, a new SVPWM control stratygy was proposed by rationally allocating the two zero vectros in the switching cycles. The method can effectively reduce the switching lossed with the guaranty of the output performance. Simulation results verify the effectiveness of the method.
