Abstract :
In this paper an exhaustive analysis of the utilization of the second harmonic component of the circulating currents in a modular multilevel converter for HVDC application is presented, with the aim of highlighting the effects on the maximum arm energy ripple, i.e. capacitors voltage ripple, and on semiconductor losses. Simulation results are presented and design remarks are indicated.
