Fuzzy Logic Based Power Factor Correction AC-DC Converter

A DC-link voltage is widely used in industrials and domestic's application. Simple diode rectifier's bridges are used to create dc voltage link. A diode rectifier has a high distortion input currents wave form and low power factor. A single phase AC–DC boost converter is realized to replace the conventional diode bridge rectifier. Fuzzy logic and hysteresis control techniques is implemented to improve the performance of the boost converter. The current loop is being controlled by using a PI, and hysteresis controllers. The fuzzy controller is applied to DC voltage loop circuit to get better performance. The results show that the fuzzy controller gives well controller. The controller is verified via MATLAB/Simulink.
