SVPWM是近年发展的一种比较新颖的控制方法，是由三相功率逆变器的六个功率开关元件组成的特定开关模式产生的脉宽调制波，能够使输出电流波形尽 可能接近于理想的正弦波形。-SVPWM is a new control method developed in recent years, is a pulse width modulation wave generating specific switch mode composed of six power switching element of the three-phase power inverter, can make the output current waveform as close as possible to the ideal sine waveform.
