具有磁耦合桥臂电感的模块化多电平变换器

The modular multilevel converter is a well-known modular multilevel topology. This paper proposes a novel branch inductor coupling and compares it to the center-tapped inductor and the standard noncoupled inductor topology. The proposed coupling has a significant influence on the inductor and converter dimensioning. Its properties make it especially well suited for use in single-to-three-phase ac/...
