在详细分析SVPWM基本原理的基础上,介绍了一种不同于传统算法的SVPWM实现方法.传统算法是将相关矢量分解到α，β轴后,根据等效关系求取各矢量的作用时间．而此法是用α－β复平面中的状态开关矢量直接进行相关矢量作用时间的求取-Different from the traditional algorithm on the basis of the detailed analysis of the basic principle of SVPWM SVPWM implementation method. Traditional algorithms related vector decomposition to α, β-axis, according to the equivalent relation strike vector time. This method is based on α-β complex plane of the state switch the vector directly related vector action time strike
