Development of three-phase to single-phase matrix converter for improvement of three-phase voltage unbalance in distribution system

In this paper, a distribution transformer using three-phase to single-phase matrix converter with an AC inductor is proposed to suppress three-phase voltage unbalance. The AC inductor is used for compensation of single-phase power pulsation at any load conditions. Control strategy and simulation results are shown in this paper. The effect of proposed method is confirmed by the simulation with MATLAB/SIMULINK.
