Abstract
Nowadays electronic equipment such as computers, televisions, audio sets and others they need to require dc power supply. Power supplies make the load compatible with its power sources. The presence of nonlinear loads result into low power factor operation of the power system. Several techniques for power factor correction and harmonic reduction have been reported and a few of them have gained greater acceptance over the others. In this paper a bridgeless power factor correction boost converter is proposed which results in improved power factor and reduced harmonics content in input line currents as compared to conventional boost converter topology. Bridgeless power factor correction boost converter eliminates the line voltage bridge rectifier in conventional boost power factor correction converter, so that the conduction loss is reduced.
