A Fuzzy Controlled SEPIC-ZETA Converter with Single Stage Operation for Application in Electric Vehicle

Abstract

In this paper a SEPIC-ZETA power factor correction converter is introduced with fuzzy control for better performance. The controller of the converter is updated with 49 rule base fuzzy interface system with 7 membership functions in each input variable. The novel proposed converter operating modes are observed with change in switching states. For application a three-phase induction machine with inverter is connected to the proposed circuit. The characteristics of the converter and the machine are studied using MATLAB Simulink environment.
