不平衡电网下PWM整流器的高增益比例谐振电压纹波抑制

Pulsewidth modulation rectifiers ensure a sinusoidal waveform of the input current, achieve a unit power factor, and maintain a stable dc voltage. However, under unbalanced grid conditions, the grid current becomes distorted, and the dc voltage exhibits a secondary ripple. To solve these problems, this article proposes a high gain proportional resonant (HGPR) ripple suppression method, the ripple ...
