的SVPWM 算法。采用SPWM 中调制波与载波相比较的规则采样思路，通过在静止坐标系下直接

计算每个参考电压矢量所对应的三相调制波的函数值，进而得到每相电压在一个PWM 周期中的占空比。-A new SVPWM algorithm. SPWM modulation used in the carrier wave, compared with the rules of sampling ideas, through the static coordinate system directly calculated for each reference voltage corresponding to the three-phase vector modulation wave function, which has been in a phase voltage of each PWM cycle accounting air ratio.
