Abstract
This paper presents power factor correction control for three phase induction motor drive using pulse width modulation current controlled technique and also presents a topology for driving a three-phase induction motor with a single-phase ac supply. Single phase boost DC-DC converter is used to obtain near unity and to reduce harmonic distortion in the main supply. In the proposed scheme, UC3854 power factor corrector is used to improve the power factor and dsPIC30F2010 controller is used to generate PWM signals. A three phase, 415V, 1.5hp induction motor is used as load for testing the developed hardware. Textronics TDS2024B storage oscilloscope is used to store the gate pulses and waveforms. The experimental result showed that power factor has increased for all the loads when power factor correction (PFC) technique is used and when compared to without power factor correction (PFC) technique.
