一种用于中压电机驱动的模块化磁耦合变换器电流应力降低方法

The modular magnetic-coupled converter (MMCC) greatly reduces the volume of the transformers and dc capacitors in medium-voltage motor drives. It consists of numerous power modules, each of which integrates several H-bridges and an intermediate dc-dc stage. The dc-dc stage utilizes six half-bridges jointly connected to the multiwinding high-frequency transformer via LC resonant tanks. This structu...
