二/三电平DAB变换器最小化电流应力的五电平控制分析与优化调制

A two-to-three-level dual-active-bridge (DAB) dc–dc converter has high potential to become a promising solution for medium-voltage high-power applications. However, its switching characteristics, modeling, and optimal modulation schemes have not been comprehensively explored yet. In order to avoid voltage and current distortions and ensure reliable operation, this article analyzes the operating co...
