Design and Implementation of MPPT Based Boost Converter Topology for Photovoltaic System

Abstract

The analysis and study of photovoltaic system is gaining utmost popularity since a decade. Unlike Conventional source of energy, solar energy is considered more beneficial because it’s renewable in nature, clean source of energy, abundantly available and can easily be generated. There is an increase in demand for generation of electricity even now, due to which researchers are looking for new implementations in the generation of electricity. The output of Solar Photovoltaic is highly dependent on quantity of irradiance dropping on the solar cell. Solar energy holds many applications amongst which Solar Photovoltaic power generation exhibits efficient utilization of solar energy. Since the efficiency of a solar cell is lesser, MPPT is employed in Photovoltaic power generation system to track maximum output power irrespective of irradiance, temperature and electrical load characteristics. In this chapter, MPPT based step-up(boost) converter topology is implemented. The output of the Photovoltaic is fed to boost converter as a connection between Photovoltaic and the load to step up the voltage. The entire operation of step-up converter for Photovoltaic system with MPPT algorithm is analyzed using MATLAB Simulink Software.
