MPPT With Buck Converter

Abstract

Due to the non-linear PV module characteristics, fluctuating ambient conditions, and dynamic load fluctuations, traditional buck converters used for MPPT have difficulty achieving high efficiency and precision. To get beyond these restrictions and improve PV system performance overall, a better MPPT algorithm and control technique are therefore required. The Perturb and Observe (P&O) method serves as the foundation for the MPPT technique employed in this project, which continuously perturbs the PV module's operating point and monitors the power output to calculate the ideal operating voltage. In order to maximize power transfer efficiency, the buck converter adjusts the voltage levels to fit the requirements of the load. It acts as a connector between the load and the PV module. The findings demonstrate how the MPPT algorithm and buck converter work together to achieve high power extraction efficiency, ensuring the best possible use of solar energy. The project's discoveries promote renewable energy technologies by making it easier to incorporate PV modules into a variety of applications, such as stand-alone power systems, solar-powered cars, and grid-connected installations.
