Neuro-Fuzzy control of 2nd order KY converter

The proposed work presented in this paper explains the novel method of Neuro-Fuzzy controller design for 2-plus-D voltage boosting KY converter, where D represents duty cycle. The converter switches are controlled by PWM (Pulse-Width Modulation) output of Neuro-Fuzzy controller to produce minimum output voltage ripple and to reduce the settling time. The simulation results illustrates that the output voltage ripple is reduced from 200mv to 1.5mv and also the settling time is improved from 25ms to 7ms. The design and performance of the converter with digitally simulated results are explained.
