This paper proposes a modified hybrid modular multilevel converters based on half-bridge submodules (HBSMs) and full-bridge submodules (FBSMs) for mediumvoltage applications. The FBSMs are used to reduce the submodule (SM) capacitor voltage fluctuations in low fundamental frequency operations by balancing the power difference between the upper and lower arms through flying inductors without the common-mode voltage injected. In addition, the FBSM can substitute a faulty HBSM if a failure in HBSM is detected and then the converter keeps its operation continuously. The viability of the proposed topology as well as the effectiveness of the control scheme have been confirmed by the simulation and experiment results.
