A New Modulation Strategy Based on Three-phase to Single-phase Matrix Converter

A new modulation strategy is proposed for three-phase to single-phase matrix converter,which combines the virtual rectifier-level space vector pulse width modulation(SVPWM)and virtual-level sine pulse width modulation(SP-WM)inverter to realize sinusoidal output with input voltages detection and simple calculation.A 1 kW three-phase to single-phase prototype is built based on four-step commutation.The experiments results show the validity and reliabili-ty of the proposed control strategy.
