Design and testing of PV maximum power tracking system with MATLAB simulation

Abstract: This paper presents the determination of unknown parameters from the given parameters of a solar panel data sheet by using the iterative method i.e. Newton-Raphson method. The values obtained from the above are used to calculate the voltage-current and voltage-power characteristics of a solar panel at different radiation and temperature conditions. The maximum power point tracking (MPPT) operation and control is developed. The Matlab/simulink set-up of PV-module gives power and the power output of module is fed to the load through a dc-dc boost converter to track the maximum power output. The Matlab/simulink arrangement of Incremental conductance algorithm is responsible for driving the dc-dc boost converter to track maximum power point (MPP). In this paper the MPP tracking is made for • A battery charging of 24 volts with varying radiation and temperature conditions. • A battery charging along with a dc load of 10 watts at standard temperature and radiation conditions (STC). • A battery discharging along with a dc load of 40 watts at standard radiation and temperature conditions (STC).

Realization of sucrose sensor using 1D photonic crystal structure vis-à-vis band gap analysis

Abstract: A 1D photonic crystal based biosensor is explored for effective sensing of sucrose concentration in an aqueous solution. The proposed structure is realized with SOI based LiNbO3–air–LiNbO3 configuration, where thickness of LiNbO3 and air layer are considered as 650 nm and 350 nm respectively. Reflected light energy from the structure is computed through analysis of a photonic band gap (PBG) by employing finite difference time domain technique. Simulations are carried out for investigation of shifts in reflected wavelength, PBG edges, PBG width, diffraction loss, reflected light energy, transmitted light energy, sensitivity and limit of detection (LOD) with reference to various sucrose concentrations. From the comparative analysis of vital sensing parameters with the existing researches, the proposed photonic sensor shows better sensitivity and low LOD which is suitable for bio sensing applications.
