Power Decoupling Control for Modular Multilevel Converter
IEEE Transactions on Power Electronics, 2018 The existing power decoupling control method of modular multilevel converter (MMC) was developed from that of conventional two-level voltage source converters. Therefore, it cannot fully realize power decoupling due to neglecting the coupling effects from submodule capacitor voltage, dc current, circulating current as well as control strategies of ...
