In this paper deals with a power factor correction (PFC) converter for AC drives using pulse width
modulation current control technique and also presents a topology for driving a three phase induction motor with a
single phase AC supply is proposed. Single phase buck and boost DC-DC converter is used to obtain near unity power
factor and to reduce the harmonic distortion in the main supply. The proposed scheme is simulated in MATLAB-2010-
SIMULINK. In the proposed scheme VHDL coding was developed to generate the sinusoidal PWM gate signal of
proposed PFC converter. A three phase, 415V, 0.5Hp, 3 phase induction motor is used as load for testing the developed
hardware. The simulation and experimental result confirms that power factor has been increased for all loads.
