用于开关周期平衡模式下模块化多电平变换器的闭环电容电压平衡方案

Modular multilevel converters (MMCs) have attracted tremendous research interest for high/medium-voltage applications due to their superior features of scalability and modularity. While successfully commercialized for a few applications, MMCs are hampered in their further widespread adoption due to voluminous cell capacitors. Recently a new switching-cycle-balancing control was proposed. It has th...
