Performance and analysis of Sepic and Non-isolated DC- DC Converter using Fuzzy controller fed PMDC motor

power electronics
This paper presents the comparison of the controller in Sepic converter and Non-isolated Converter to decrease the ripple content, switching losses, conducting losses and enhanced the efficiency. Fuzzy logic (FL) control is recognized to be non-mathematical and flexible in nature that provides faster and more reliable performance under varying parameters and load disturbance, determining the member function. The output voltage is obtained at constant PWM generation from the fuzzy logic controller with Non-isolated and Sepic converter. These are simulated, fabricated and tested with R-load and Motor load. Closed loop system is also simulated. The hardware results with the simulation results are verified. The efficiency of the proposed Sepic converter is improved from 94% to 97.1%
