| Abstract |
In this paper, the reduction of the modular multilevel matrix converter (M3C) to eight branches is investigated in a branch failure event. In order to operate this reduced topology, circulating currents have to be injected so that the branch power imbalance caused by the asymmetrical branch configuration can be compensated. Using an analytical model, a novel approach is derivedin which the circulating currents are selected in such a way that the branch current losses and the branch energy variations are reduced. The novel approach is comparedto other reduced topologies in terms of branch losses and branch energy variations at different operating points. |
