摘　　要：基于正弦脉宽调制(sine pulse width modulation,SPWM)与空间矢量脉宽调制(space vector pulse widthmodulation,SVPWM)的基本原理,分析并论证两种算法在性质上的一致性。建立两种算法所在算法空间的一一映射关系,分析并得到两种算法基于基本载波周期的宏观差值函数——零序空间矢量基本函数。基于零序空间矢量基本函数确定的零序分量,将SVPWM等价映射为基波调制波中注入该零序分量的SPWM,建立从载波角度研究SVPWM的新方法。从外部输出结果与内部分析效能两个方面对所得结论进行数值仿真,证明了所得结论的正确性和有效性。Based on the basic rules of sine pulse width modulation(SPWM) and space vector pulse width modulation(SVPWM),the same identity of the two algorithms was analyzed and derived.The mapping relationship of the two calculation space was established.For the foundational period,it analyzed and derived the 0th Space-Vector basic function,which is the macro-error function between the two algorithm.With 0th harmonic decided by the 0th Space-Vector basic function,SVPWM is equalized to be SPWM with the harmonic injected,which is a new way to research SVPWM by the carrier based method.With the simulation of the output results and internal analyzing abilities,the conclusion derived is proved to be right and effective.
