This paper describes the design of a fuzzy logic controller using voltage output as feedback for significantly improving the dynamic performance of single phase AC to DC power factor correction interleaved boost converter by using Simulink MATLAB software and validate the result by the 600W converter hardware. The objective of this proposed methodology is to develop fuzzy logic controller on control Power Factor Correction PFC interleaved boost AC to DC converter using Simulink MATLAB software. The fuzzy logic controller has been implemented to the system by developing fuzzy logic control algorithm. The design and calculation of the components especially for the inductor has been done to ensure the converter operates in continuous conduction mode. The evaluation of the output has been carried out and compared by software simulation using MATLAB software between the open loop and closed loop circuit. The simulation results are shown that voltage output is able to be control in steady state condition for single phase AC to DC power factor correction interleaved boost converter by using this methodology. The focus of this paper involves the design and implementation of an interleaved PFC for high performance and small size, the controller design and implementation of boost DC DC converter. Based on this, an optimal topology is selected for which an additional comparative analysis involving input line measure improvement control is conducted by using PI controller. The results of these experiments can be adapted for use in the circuit selection of high performance converters with power factor improvement circuits. Pranali V.
