Abstract: The integration of solar photovoltaic (PV) systems into the electrical grid requires efficient power electronic interfaces to ensure reliable operation and maximum energy extraction. This study focuses on the design and performance analysis of a power electronic interface for grid-connected solar PV systems incorporating Maximum Power Point Tracking (MPPT) techniques. A DC–DC converter controlled by MPPT algorithms such as Perturb and Observe (P&O) and Incremental Conductance (INC) is employed to optimize the PV output under varying irradiance and temperature conditions. The conditioned DC power is subsequently converted into synchronized AC power through a voltage source inverter (VSI) with appropriate grid synchronization and control strategies. The proposed system enhances the efficiency, stability, and power quality of PV-grid integration while minimizing harmonic distortion and ensuring compliance with grid codes. Simulation and experimental results validate that the implementation of an optimized MPPT-based power electronic interface significantly improves energy harvesting capability and supports sustainable and reliable integration of renewable energy into the power grid.
