The paper presents a drive system consists of single-phase boost rectifier, space vector pulse width modulation (SVPWM) inverter, and three-phase induction motor. The single-phase boost rectifier is used to obtain near unity power factor and to reduce the harmonic distortion in the main supply. The SVPWM inverter is used to offer 15% increase in the output voltage and low output harmonic distortions compared with the conventional pulse width modulation (PWM) inverter. The input/output performance of the proposed model of single-phase to three-phase converter feeding an induction motor is simulated with different loading conditions.
