DC–DC power converters are characterized by cyclic switching of circuit configurations, which gives rise to a variety of nonlinear behaviours. Their occurrence in DC–DC power converters makes the system analysis, control and behaviour prediction difficult. An enhanced modelling method allowing one to obtain an accurate description of the converter behaviour is presented in this paper. A fuzzy control scheme is proposed, and a fuzzy logic controller is then developed to both suppress converter nonlinear phenomena and ensure the averaged input current regulation for a wide range of parameters' variation.
