矩阵式模块化多电平变换器能量平衡方法性能分析

Modular multilevel converters (MMCs) achieve voltage scalability through the series connection of cells, each with its own capacitance. However, this converter structure using floating energy storage elements increases the control complexity significantly. The voltages of each capacitance must be controlled to their respective setpoints to ensure the correct operation of the converter. Relying on ...
