基于半桥直接矩阵结构的双向AC/DC变换器调制方法

This letter proposes a half-bridge bidirectional isolated matrix-based ac/dc converter for compact ac/dc power conversion applications. The converter can control not only the dc voltage or current, but also the power factor of the ac current with a single conversion stage, which helps to achieve a higher power density with a lower complexity. The converter operates with zero-voltage switching or z...
