Design of Fuzzy logic controller for output voltage ripple (OVR) reduction of KY boost converter

KY Boost Converter, a recent invention in the field of non-isolated DC-DC boost converter is identified for minimum voltage ripple. In this article a Fuzzy controller is designed and implemented to minimize the output voltage ripple of the KY boost converter output. The Fuzzy controller is designed in MATLAB/Simulink model and the digitally simulated results show a reduction in output ripple from 200mV of the existing FID controlled converter output to 10mV in the proposed Fuzzy controlled converter and the settling time of the output is found to be fast in comparison with the existing PID controller output.
