Design And Simulation Of DC-DC Converter Topologies In Solar Photovoltaic System

Abstract

Photovoltaic (PV) is one alternative source of renewable energy. The output power from a PV system varies because it is highly dependent on the irradiance and temperature. Selection of the appropriate DC-DC converter is essential because it plays an important role in the overall performance of the PV system. Study of DC-DC converter topologies like boost, buck-boost, and Cuk is carried out in this paper. The performance of the simulation models have been compared by simulating them one by one in the MATLAB/Simulink platform. The boost converter gives less output power in comparison to other converters. The buck-boost and Cuk converters give almost 80% output power. The Cuk converter improves transient response and also gives less ripple in output power in comparison to the other converters.
