| 摘 要： | 通过对SVPWM的调制函数模型进行分析，找到了SPWM和SVPWM调制方式的内在联系．并依据SVP-WM的相电压和线电压调制模型及MATLAB仿真波形，证明三相电压型整流器在SPWM和SVPWM两种调制方式下基波电流波形都为正弦波，可以用于PWM整流器的电流环控制．

| Abstract: | The modulation function model of space vector PWM(SVPWM) was analyzed and the internal relations between sinusoidal PWM(SPWM) and space vector PWM were found.Based on the simulation results of the MATLAB,the fundamental current waveforms of SPWM and SVPWM modulation methods were proved to be sine wave in the three-phase voltage rectifier,which can be used in the current loop control of PWM rectifier. |
