A generalized three-phase multilevel current-source inverter (MCSI) topology is proposed by implanting the generalized N-level current cells into a three-phase MCSI topology which is derived from the three-phase multilevel voltage-source inverter (MVSI) topology through dual conversion. In the generalized three-phase MCSI topology, each intermediate dc-link current level can be automatically balanced without adding any external circuits, thus a true multilevel structure is provided. Output current of each phase is independently modulated because of being supplied with two DC current-sources. This allows the wealth of existing knowledge relating to the operations, modulations and control strategies of multilevel VSI to be immediately applied to such multilevel CSI. Simulation results of 5-level and 7-level CSI systems are presented to verify the proposed three-phase MCSI topology.
