考虑中点电压波动与不平衡的维也纳整流器改进载波DPWM调制策略

Discontinuous pulsewidth modulation (DPWM) has been widely used in the three-level Vienna rectifiers due to its higher efficiency. However, for dual output load applications, vector synthesis error will be introduced by oscillated and unbalanced neutral-point (NP) voltages after using conventional DPWM without NP balance control, which results in extra input current distortion. In this article, an...
