In this paper the effects of the circulating currents on the modular multilevel converter, for HVDC applications, are presented. The first part is a review of an analytical study of the converter, aimed to minimize the capacitors rms current. In the second part the effects on the converter efficiency and on the safe operating area (SOA) margins are studied.

Abstract
In this paper the effects of the circulating currents on the modular multilevel converter, for HVDC applications, are presented. The first part is a review of an analytical study of the converter, aimed to minimize the capacitors rms current. In the second part the effects on the converter efficiency and on the safe operating area (SOA) margins are studied.
