In this paper, the design of a fuzzy logic controller based quad buck-boost converter with constant input and output current is presented. In contrast with the ordinary step-down-up converters the advanced converter with same duty cycle, a large limit of voltage conversion ratio could be acquired. A proposed converter is designed and studied with an intelligent controller i.e. fuzzy logic controller/FLC and differentiated with the ordinary Proportional-Integral /PIC controller. Finally, the analysis of the presented converter by employing MATLAB/Simulink, simulation results of the presented converter is recorded to substantiate the effectualness and rationality of the output voltage control of Quad buck-boost converter in both step-down-up mode and its comparative analysis is presented where the fuzzy logic has a minimum overshoot and settling time compared to regular PI controller.
