SVPWM是近年来发展比较新的控制方法，是由三相功率逆变器的6个功率开关组成的特定开关模式产生的脉宽调制波，使输出的尽可能接近正弦波。(SVPWM is a relatively new control method developed in recent years. It is a pulse width modulation wave generated by a specific switching mode composed of 6 power switches of three-phase power inverter, so as to make the output as close to sine wave as possible.)
