用于三相三电平变换器直流母线电容减小的综合载波基不连续PWM策略

The input current distortion issue associated with discontinuous pulsewidth modulation (DPWM) is a significant concern for three-level Vienna rectifiers. While larger dc-link electrolytic capacitors can help mitigate this issue by reducing neutral-point voltage oscillations, they also lead to a substantial increase in the volume of converters. This article presents consolidated carrier-based DPWM ...
