Modeling of Neuro Fuzzy Controller for Negative Output KY Boost Converter Voltage Ripple Reduction
Keywords:DC-DC converter, KY boost converter, neuro fuzzy, ripple reduction
AbstractNegative output KY Boost converter is a recently proposed system by K. I. Hwu et. Al. This converter produces low output voltage ripple than the conventional DC-DC negative voltage boosting converters. In this manuscript a Neuro Fuzzy controller is modeled to control the output voltage ripple and to reduce the peak overshoot and settling time of the converter. The results of proposed Neuro Fuzzy controlled negative output KY boost converter with the digital simulation by Matlab/Simulink® shows reduction in voltage ripple from 60 milli Volts of the existing PI controlled system to 3 milli Volts by the proposed Neuro Fuzzy controlled negative output KY boost converter. Also the peak overshoot of the system and its settling time are reduced to a greater extent with the proposed system.
