Optimized Voltage Equalization Algorithm for Modular Multilevel Converters
Year: 2023
Type: conference-paper
Abstract: The switching frequency of modular multilevel converters increases with the number of bridge arm submodules. Therefore, an improved voltage equalization technology based on fast sorting algorithm is proposed, which introduces the maximum voltage deviation between sub-modules and reduces the unnecessary switching operations caused by small changes in the capacitor voltage of factor modules. With the help of Matlab/Simulink, a modular multilevel converter with optimized control was simulated to verify the downscaling effect of the voltage-sharing optimization method.
