A new algorithm is proposed in this paper for switch reduction in multi-output single-phase converters. The idea is first explained by introducing the dual-output six-switch inverter and then generalized into the switch reduction of m-output topology. Two modes of operation are defined for the proposed converter and the modulation scheme of each mode is devised. To compensate for the reduced dc bus...
Despite all the unique features multilevel converters offer, their high number of required power switches has restricted their implementation to particular applications. To mitigate this problem, a novel multilevel ac/ac converter is proposed in this paper which utilises less number of semiconductor devices in its structure. The proposed converter is achieved by cascading recently introduced reduced...
This paper proposes a novel inverter for supplying unbalanced four-wire three-phase loads. The inverter has two three-phase outputs that operate with independent frequencies and amplitudes. Within each output, each phase can have independent voltage magnitude, but the frequency is the same for all phases. The topology is developed by adding an extra leg to a nine-switch converter. Moreover, it benefits...
