Single-Phase to Three-Phase PWM Converters

Abstract

Voltage source and current source power converters with single-phase input and three-phase output are presented. Both converters consist of three legs and a three-phase power module only is used. The normal PWM methods with the sinusoidal modulating wave and the triangular carrier wave are employed for sinusoidal waves in ac sides. The simulated waveforms are shown and these results confirm that the converters under the PWM operation can generate the sinusoidal voltages and currents.
