Optimization Technique for Improving the Performance of PV based Self-Lift Luo Converter

Abstract

The paper presents a self-lift Luo converter for photo-voltaic (PV) based application. Proposed Luo converter exhibits high-gain characteristics yielding high output DC level required for PV applications. The photovoltaic cells are operated at their maximum power point using Maximum Power Point Tracking (MPPT) techniques. Illumination, temperature, radiation intensity are some of the factors that can influence the maximum power point. Particle swarm optimization (PSO) based Maximum Power Point Tracking (MPPT) is employed with PID controller to track the maximum power from the PV cell. Duty cycle for Luo converter is generated by sensing the panel voltage, current and the corresponding power values. Simulation analysis is presented using MATLAB/SIMULINK software for PV with Luo converter with PSO technique.
