چکیده:

This paper presents a modified design of a slidingmode controller based on fuzzy logic for a New ZVThigh stepup DC-DC Converter . Here a proportional – integral (PI)-typecurrent mode control is employed and a sliding modecontroller is designed utilizing fuzzy algorithm. Sliding modecontroller guarantees robustness against all variations andfuzzy logic helps to reduce chattering phenomenon due tosliding controller, in that way efficiency increases and error,voltage and current ripples decreases. The proposed system issimulated using MATLAB / SIMULINK. This model is testedunder variations of input and reference voltages and it wasfound that in comparison with conventional sliding modecontrollers they perform better.
