FLC based Quasi-Z-Source Topology Using Dc-Dc Converter with Synchronous Rectification

Abstract

The objective of this research is a bidirectional dc-dc converter with a quasi-z-source topology. Under this situation, the battery acts as a full-bridge converter during discharging and as a half-bridge converter during charging, with a synchronized full-bridge converter with LC filtering mode. In this method, a fuzzy PI controller is used with quasi-z-source topology to improve the performance and reduce the distortion in waveform. Here an advanced quasi-z-source network is used for quality improvement and the solidity under disturbance are done by using fuzzy rule. In the system the design and modeling is done in the MATLAB Simulink model. The proposed system involves the method of the fuzzy logic controller to control the changes in input and output and also analyze the data obtained by the FLC method.
