基于载波移相调制的MMC热备用子模块容错控制

Reliability is one of the most important challenges for the modular multilevel converter (MMC), which is composed of a large number of power electronics submodules (SMs). In order to increase the system reliability, the reserved SMs are often utilized. A novel strategy is proposed in this paper to implement the fault-tolerant control of MMC with the hot reserved SMs based on the carrier phase shif...
