Abstract

A solar panel is able to generate optimal power when it is constantly exposed to the maximum amount of solar radiation, which causes its output voltage and current to constantly reach their peak values. Determining whether the microinverter panel can reach maximum output power when connected to a solar panel is the goal of this research project. This is accomplished through the perpetual maintenance of the solar array at its Maximum Power Point (MPP). The project's objective is to develop and implement a comprehensive microinverter system, comprising a full-bridge DC-DC converter and a single-phase H-bridge inverter. The primary goals include achieving efficient power conversion and implementing maximum power point tracking (MPPT) control for optimal energy harvesting in photovoltaic applications. The project scope involves designing and analyzing the full-bridge DC-DC converter using MATLAB/Simulink, serving as the initial stage of the microinverter. Following this, a 500W power-rated DC-AC converter is integrated as the second stage, utilizing an H-bridge inverter. The project scrutinizes the efficiency of the MPPT controller for the full-bridge DC-DC converter to enhance the overall system performance. Additionally, a comparative analysis evaluates the microinverter's efficiency against a string inverter, providing insights into its operational effectiveness. The utilization of the H-bridge inverter for the DC-AC conversion stage enhances the versatility and robustness of the microinverter system. Ultimately, this project contributes to advancing the field of renewable energy systems by offering a detailed exploration of the microinverter's functionality and performance under various conditions.
