Evaluation and Operation of Various DC-DC Converter Topologies with Effective MPPT in a Photovoltaic System

Abstract

This article describes the reliable and efficient DC-DC converter for Renewable Energy Sources. The system will function more accurately when the solar panel's irradiance is low. The Maximum Power Point Tracking (MPPT) control algorithm is used to operate the similar system in order to achieve greater efficiency. The characteristics curves for solar panel current v/s voltage (I–V) and power v/s voltage (P–V) are produced by MATLAB simulation. The curves derived from the experiment results are also compared to the simulation curves. A thorough analysis of solar-fed DC–DC converters (Boost, Push-Pull, and Coupled Inductor based converter) is also carried out. The proposed converters are simulated in MATLAB. Simulation results are presented and discussed. Results demonstrate the validity of the models.
