Performance comparison of pv module using inc mppt with boost & sepic converter

Abstract

Nowadays, at this stage of energy crisis, it has become essential to switch towards renewable energy sources from conventional sources of energy to obtain power. Among all other renewable sources, solar energy is getting more attention in a country like India due to its abundant availability. This paper presents a study on Photovoltaic Module. As we know, solar energy is intermittent in nature, i.e. it varies according to the environment conditions, so we need to have some sort mechanism that helps it to operate efficiently. In this paper, an Incremental Conductance MPPT has been used to track that maximum power for the different environmental conditions. After tracking the maximum power, we need to obtain that power by changing the voltage and current values. This is done by changing the duty cycle of the DC-DC converters which gets its pulses through the MPPT and firing circuits and accordingly changes the voltage and current values. So, in this paper a study on PV module using INC Conductance MPPT with Boost and SEPIC Converter is presented and their values are obtained and compared for different environmental conditions. The whole system is simulated on MATLAB/Simulink. IJSTR©2019.
