چکیده :

This article explores the design and optimization of a 2 kW grid-connected microinverter, focusing on its control system to enhance efficiency and reliability. We emphasize key aspects such as Maximum Power Point Tracking (MPPT), Phase-Locked Loop (PLL) synchronization, and the management of active and reactive power. The study integrates Proportional-Integral (PI) control methods with advanced power management strategies to address challenges in phase and amplitude adjustment, ensuring zero reactive power and maintaining grid stability. A prototype was developed to validate the proposed design and control strategies, featuring distinct sections for DC-DC and DC-AC conversion with the HERIC topology. Experimental results confirm the system’s effectiveness in power transfer and demonstrate the successful implementation of the control system. This research contributes to improving microinverter technology, providing a scalable solution for integrating photovoltaic systems with the electrical grid.
