| Abstract: | This paper analyzes the working principle and fault characteristics of modular multilevel converter (MMC) and builds a five-level MMC fault simulation platform based on MATLAB/Simulink. Open circuit, short circuit and high impedance faults of IGBT devices in a submodule are simulated, and the variation patterns of output DC voltage, capacitance voltages of sub-modules and three-phase AC currents when IGBT has different faults are summarized, which provides the reference for MMC fault diagnosis and location. |
