The power converters are widely used in many applications to reduce the switching losses and to increase the efficiency the soft switching technique are used. The close loop control of soft switching DC-DC Boost converter consists of development of fuzzy logic controller for generating control PWM pulses of required duty cycle for MOSFET of the converter to maintain the constant output voltage. Duty cycle of the converter is adjusted continuously to obtain required output voltage for variable input voltage. This paper describes the design of fuzzy logic controller using output voltage of the converter as feedback for significantly improving the dynamic performance of soft switching DC-DC boost converter by using MATLAB/Simulink.
