针对模块化多电平变流（MMC）用于高压直流输电（HVDC）领域时子模块数目较多的需求．探讨了一种三级控制器的系统架构方法，不仅减少了子模块和主控制器之间的光纤连接数目。还增加了子模块控制的灵活性；分析了此种控制结构的模块同步问题并给出了较好的解决办法。设计并搭建了一个单相实验平台，用实验验证了三级控制器设计的可行性。

According to the demand of the increasing number of sub-modules in Modular Multilevel Converter （MMC） used in the field of High Voltage Direct Current Transmission （HVDC）, a three-level controller was discussed to reduce the number of fiber between the sub-modules and controller and increase the flexibility of the sub-module. Meanwhile a solution of module asynchronous phenomenon caused by the special controUer was given. Then, the validity of the proposed controller architecture was verified by experimental results obtained fi：om a one phase prototype.
