Boost converter based power factor correction for single phase rectifier using fuzzy logic control

Abstract

Power Factor which is the ratio between the real or actual power and the apparent power is a very essential parameter in power system. It indicates how effectively the real power of the system has been utilized. In any electrical power system, a load with a low power factor draws more current than a high power factor load, for the same amount of useful power transferred. The most popular topology in Power Factor Correction (PFC) applications is certainly the boost topology. The boost topology is very simple and allows low-distorted input currents and almost unity power factor with different control techniques. A new fuzzy logic control strategy in a boost converter based PFC method for single phase rectifier is presented in this work. The proposed fuzzy logic control system has two inputs and one output. The proposed PFC control is based on boost converter operating at continuous conduction mode and provides a higher switching frequency.
