Smart Energy Management in EV Charging Stations Using a PV-Based Boost Converter and Multilevel Inverter

A grid-integrated electric vehicle (EV) charging system that is powered by a photovoltaic (PV) source is presented in this research. The system is designed to be very efficient. A PV panel, a boost converter, and a seven-level multilevel inverter (MLI) are the components that make up the system. These components work together to provide reliable and high-quality power transmission to the grid and electricity charging station. The suggested system functions under situations that are typical of grid operations. While the boost converter is responsible for maximising the amount of power extracted from the PV panel, the MLI is responsible for improving the quality of the output waveform and minimising total harmonic distortion (THD). To achieve optimum switching, minimise power losses, and guarantee high efficiency, a technology known as pulse width modulation (SPWM) is used. Through the use of MATLAB simulations and comprehensive analysis of the system parameters, the performance of the system is assessed. The findings demonstrate that the system is capable of achieving low total harmonic distortion (THD), high efficiency, and reliable grid operation, making it sustainable for electric vehicle charging infrastructure.
