Implementation of photo voltaic based improved negative output self-lift luo converter using particle swarm optimization

Abstract

This project deals with an improved modifications of the negative output super-lift Luo converter that allows significant increase in the voltage transfer gain. The negative output super-lift Luo converter gives high negative output by using the VL technique. The input to the converter given by photovoltaic module. A PV module consists of number of series connected PV cells to produce higher voltage. A photovoltaic cell converts the solar energy into the electrical energy by the photovoltaic effect. The photovoltaic cells must be operated at their maximum power point. The maximum power point varies with illumination, temperature, radiation intensity. To track the maximum power from the PV cell, a technique named Particle swarm optimization (PSO) Maximum Power Point Tracking (MPPT) is employed with PID controller. In this method, the duty cycle is generated by the sensing of the panel voltage and current and the corresponding power values of it. Once the local maximum point of the voltage is reached, the Particle Swarm Optimization technique takes this point as a reference and generates the best duty cycle needed for tracking the maximum power from the PV cell. The proposed system is modelled and simulated using MATLAB/Simulink.
