Control strategies for capacitor voltage balancing in modular multilevel converters [PDF]
2016 7th International Renewable Energy Congress (IREC), 2016 Different schemes of modified conventional sorting algorithms with low complexity are proposed in order to balance the voltages of submodule (SM) capacitors for the modular multilevel converter (MMC). Two different procedures are investigated in this study. The main idea is to achieve voltage balance within the MMC arms with fewer current sensors.
