Fuzzy logic controller (FLC): Application to control DC-DC buck converter

Nowadays, DC-DC converters circuits are widely used in electronics systems in order to obtain a stabilized output voltage from a given input DC Voltage. Performance of DC-DC converters is dependent on the choice of control methods. Consequently, controlling of DC-DC converter represents essential task in power conversion. The research problem addressed in this paper is to model a controlling system for buck DC-DC converter. In this way a logic fuzzy controller is used and simulated using MAT LAB/SI MULINK to increase converter efficiency and power efficiency.
