Impact of circulating current control in capacitor voltage ripples of modular multilevel converters under grid imbalances
The negative-sequence current of a modular multilevel converter (MMC) under unbalanced ac grid conditions increases the voltage ripples of the submodule capacitors. This paper investigates the impact of circulating current control in capacitor voltage ripples under different unbalanced ac grid condi...
