三电平混合模块化多电平变换器的建模与控制方法

The modular multilevel converter (MMC) is one of the most favored topologies for medium and high voltage applications. However, the drawbacks, such as lots of capacitors and doubled number of devices, limit the power density. Recently proposed hybrid multilevel converters with high voltage switches and chain-links have shown the superior performance compared with the traditional MMC. Specifically,...
