ABSTRACT: This paper presents a comparative evaluation of proportional-integral and fuzzy logic controller to a constant frequency zero voltage switching quasi resonant buck-boost converter. Sensitivity of these controllers to load disturbances are studied and results are presented. The simulation study indicates, the superiority of fuzzy control over the conventional control methods. Fuzzy logic seems to have a lot of promise in the application of power electronics.
