This paper presents two single-phase to threephase conversion systems for a three-phase load application. The load is connected to a single-phase grid through an AC-DC-AC single-phase to three-phase converter. The single-phase rectifier is composed of two parallel singlephase half-bridge rectifiers. The first proposed topology is composed of a full-bridge three-phase inverter, i.e., threeleg inverter, while the other topology is composed of a twoleg inverter. Suitable modelling, including the circulation current, and control strategy are presented. A pulse widthmodulation (PWM) technique using a single or double carriers PWM implementation is presented. Proposed topologies permit to improve the harmonic distortion. In addition, it can reduce the converter power losses. Finally, simulation and experimental results are presented for validation purposes.
