准方波调制下串联桥臂模块化多电平DC/DC变换器的建模与电流前馈控制

The modular multilevel dc–dc converter emerges as a promising solution for the medium-voltage (MV) dc system due to its galvanic isolation, voltage conversion, and bidirectional power transmission capabilities. However, different from the traditional dc–dc converter, both the circulating energy and transmission power must be precisely controlled to achieve high dynamic and steady-state performance...
