模块化多电平变换器的器件级损耗平衡控制

Modular multilevel converter (MMC) is a promising topology in medium/high-voltage applications for its merits, e.g., scalability, low output current total harmonic distortion, and high efficiency. But the reliability of MMCs is questionable due to more semiconductor devices used than other topologies. Another reliability problem of MMC is the significant uneven loss distribution between the top an...
