摘　　要：提出了一种简便可行的SVPWM过调制策略。根据输出矢量在角度和幅值上的连续性,将过调制区域分成了两部分;并提出了每个分区的过调制策略以及相应电压矢量基波的数学表达式。最后,针对上述策略,给出了一种可实现的工程方法,并进行了相关的实验。实验结果证明了该策略的可行性。A method of SVPWM over-modulation which is easy to be implemented was proposed.According to the continuity of angle and amplitude,the over-modulation range could be divided into two parts.The theory of over-modulation and the expression of the fundamental voltage magnetic in each part were presented with each part′s characteristic.At last,based on the theory of over-modulation,a realizable engineering method was proposed.This method was used to finish the experiment and the theory was proved to be available.
