A Reverse-Biased Voltage Controlling Method for Mitigating Arm Overcurrent and Submodule Overvoltage in Hybrid MMCs During DC Faults

Abstract: Blocking all submodules (SMs) of the hybrid modular multilevel converter is a simple way to clear dc fault currents. However, each arm's reverse-biased voltage (RBV) is uncontrolled in this ...
