A study on load voltage control method for three-phase-to-single-phase Matrix Converter system with neutral line

A control method of a Matrix Converter to convert from four-wired three-phase voltages to three-wired single-phase voltages (single-phase MC) which replaces transformer in consumer side on micro-grid is studied. In the single-phase MC, voltage drop and phase shift in its load voltage are occurred because of line current flow in input and output filters. However, it´s necessary to compensate them to supply symmetrical two-phase AC load voltages for consumer side. In this paper a control method of the load voltage of the single-phase MC is proposed, and the effectiveness of the proposed method is verified by simulation results.
