Suitable single-phase to three-phase AC-DC-AC power conversion system

This paper presents a single-phase to three-phase power conversion system with parallel rectifier and series inverter to cope with single-phase to three-phase asymmetry. Such converter guarantees both reduction in the input current processed by rectifier circuit and reduction of the output voltage processed by inverter circuit. It is worth to mention that, in spite of proposing a topology with features no longer observed in the technical literature, this paper presents a comprehensive model of the proposed converter, modulation strategy and a general comparison with the conventional configuration. Simulated and experimental results are also presented.
