Implementation of intelligent fuzzy controller for positive output Relift LUO converter

Abstract

Faster development in Dc to Dc converter techniques are undergoing very drastic changes due to that major advancements like low voltage, high power density in electronic industry. The positive output Relift LUO converter is a novel Dc to Dc voltage gain converter, which uses voltage lift technique for the conversion of positive input source voltage to positive output load voltage. Complex behavior characteristics like nonlinear and time variant make the converter works in switch mode. For the above choosen converter conventional controller provides in efficient performance and hence fuzzy controller is implemented for the present luo converter work, the fuzzy control is proposed as a computational intelligence techniques for the purpose better regulation as well as the performance of the converter, the output regulation of the present luo converter is validated with the help of model free fuzzy logic controller. The MATLAB simulation as well as hardware(TMS320F2407) results of the closed loop performance of the positive output Relift luo converter under line and load disturbance is evaluated by using robust fuzzy logic controller, under various conditions the satisfactory performance of the controller is found to be better.
