This paper presents the design of Fuzzy Logic Controller (FLC) plus Proportional Controller (PC) FLC plus PC for KY Positive Output Boost Converter (KY-POBC) for low power LED driver application. The characteristic of the KY-POBC is intricate owing to the time varying and on/off nature of it. So as to improve the load voltage regulation of the KY-POBC, a VFBSMC is developed. The fuzzy rules are framed based on the system performance. PC and PI controller parameters are computed with help of state space averaging modeling of KY-POBC. The performance of the designed model is verified by developing the model in comparison with classical proportional-integral controller. The simulated results are presented to show the proficient of the designed controller.
