Abstract We proposed a novel temperature sensor based on dual core photonic crystal fiber (DCPCF) and applying different twisting on its cladding surface. The temperature dependent chloroform is applied as analyte. The sensitivity is calculated for different twist (10 rad/mm and 15 rad/mm). - Numerical investigation of co-doped microstructured fiber with two zero dispersion wavelengths

KY boost converter is a recently invented in DC-DC converter topology by K. I. Hwu and Y. T. Yau. This converter operates in continuous conduction mode with low output voltage ripple in the order of few mV, fast transient response and settling time yielding larger voltage conversion ratio. In this work, Neuro Fuzzy control technique is proposed to reduce the output voltage ripple and to achieve fast settling time. The digitally simulated results are obtained using MATLAB/Simulink with reduced voltage ripple in the order of µV along with fast settling time. The proposed controller is devised with a microcontroller which is embedded with Neuro Fuzzy algorithm to regulate the output voltage of the converter and the experimental result has validated the simulation result.

Negative 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.

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. - Neuro-Fuzzy control of 2<sup>nd</sup> 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.
