DESIGN OF PUSH PULL QUASI RESONANT BOOST CONVERTER FOR POWER FACTOR CORRECTION ABSTRACT This project proposes power factor correction using push pull quasi resonant converter. A boost power factor corrector converts universal AC input voltage into regulated DC output voltage. This converter is composed of transition mode boost type power factor corrector and a coupled inductor. By integrating two inductors into a single magnetic core, the operating frequency is being doubled of switching frequency. Transition mode power factor correction is to reduce the switching loss and two boost inductors are used to drive and achieve transition mode operation. The power factor is corrected by the occurrence of resonance condition in the converter. In conventional method, PID controller was used so that the switching and conduction losses are high. Fuzzy controller gives accurate output by adding new rules. Fuzzy controller is used in the proposed system to reduce the losses and also to improve the power factor.
