Design of Cuk Converter based three phase inverter by fuzzy controller

This concept proposes a new cuk converter based three phase inverter controlled by fuzzy control system. In this proposed system buck boost property of cuk converter is based on the time varying duty ratio which provide more workability. The features of this proposed system is that the inductor and capacitor rating is diminish to increase reliability, minimize the area and total system expanse. In electrical control systems there are many methods to control the process. Like P, PI, PID, etc. PI controller requires mathematical model and Fuzzy control is totally based on the Linguistic Variables and it is easy to implement. The proposed system has many advantages as compared with conventional systems. The cuk converter set the output voltage at desired voltage by simulating to grid. The performance of cuk converter using fuzzy controller with three phase inverter simulated by using MATLAB/Simulink.
