一种利用开关电容滤波器实现两电平逆变器驱动感应电机全速范围谐波抑制的方案

This paper proposes a novel harmonic suppression scheme for two-level inverter fed three-terminal induction motor drives using switched capacitive filter. Capacitor fed H-bridges used as filters are cascaded to conventional two-level inverter to eliminate fifth- and seventh-order harmonics for the full modulation range including a six-step operation. For the first time, two-level dodecagonal volta...
