Analysis of Converters for Photovoltaic System

Abstract

Country’s economic progress rely on the energy which acts as key for development. The energy consumption is on a large scale because of expeditive growth of industries, increased vehicular usage and domestic consumers. The energy produced by fossil fuel causes air pollution which increase the global temperature. To reduce the carbon footprint is a challenging task to conserve the environment. Therefore, people look out for alternative energy sources for power production. In spite of COVID pandemic the energy source which has a rapid growth in last few years is renewable energy sources The developing countries are trying to overwhelm issues relating to generation of power using these conventional energy sources. Solar and wind meet the demand desideratum with the help of converters and controllers. Among these renewable resources most feasible is solar photovoltaic power, because of its unique features such as no rotating parts, doesn’t expel any harmful gases, mobility, noiseless that is eco-friendly in nature. Since PV depends on unalterable factors such as irradiance, temperature it suffers from stability, conversion efficiency etc. For extracting maximum power from PV DC-DC converters play a vital role. The converters must have the capability to boost the voltage, reduce ripples and must be stable to meet the needs of Photo Voltaic array - PV Array. Its performance can be further improved by integrating converter with Maximum power point tracking technique. In case of Wind energy system converter must have the capability to have control over reactive power, reduced harmonics, reactive compensation issues. This paper analyses and proposes best converter for PV system that has high gain.
