        abstract = {The integration of large-scale photovoltaic (PV) systems with the utility grid requires a reliable power electronic interface to regulate the DC-link voltage while extracting maximum power from the PV array. This paper investigates the use of a Buck–Boost converter in a 3 MW grid-connected PV System. The Buck–Boost converter provides the dual functionality of voltage step-up and step-down operation, thus ensuring stable DC-link voltage under a wide range of PV operating conditions. The converter design is carried out considering inductor current ripple, capacitor voltage ripple, and semiconductor device stresses at full load. Simulation studies are performed in MATLAB/Simulink to validate the performance of the proposed system under varying solar irradiation and temperature conditions. The results confirm that the Buck–Boost converter enhances voltage regulation capability, ensures effective maximum power point tracking (MPPT), and provides improved operational flexibility.},
