The field of telecommunication is booming up in a rapid manner and is always consorted with the growth of affirming equipments like power supplies. Efficient converters have to be used wherein the power quality is not deteriorated because of the interruption in the load. Here a three phase, single stage power factor correction converter is presented which has got distinguished features such as less distorted input current without deadband region and high power factor, less stress on switches and continuous output current for a wide range of load variation. Also this efficient converter is controlled using the conventional proportional-integral (PI) controller and fuzzy logic controller (FLC). The performance parameters are compared and found that FLC is more robust to parameter variations. The features, performance indices, simulation results obtained with the help of MatLab software are also presented.
