The capacitor voltage ripples and the circulating currents in the MMC arm are electrically coupled, when the circulating currents are suppressed, the capacitor voltage ripples will be reduced as well [11]. Hence the lifetime of the capacitors will be extended and this is also the case for the failure rates of all the SMs in the same arm [12,13].
