The theoretical analysis and result of simulation indicate that the two - phase modulation reduces the switching losses 50 % relative to the quasi - optimum and the space vector modulation and overmodulation can generate higher voltages with low total harmonic distortion 分析表明二相调制方法相对于准优化方法减少开关损耗近30 ，空间矢量的调制与过调制可以大大的提高直流母线电压的利用率。
