This paper delves into the vital role of converters in enhancing the efficiency and reliability of solar photovoltaic (PV) systems. With the escalating demand for renewable energy sources, solar PV systems emerge as a sustainable solution, necessitating advanced power electronics for optimal performance. The study highlights various DC-DC converters, such as buck, boost, and buck-boost converters, analyzing their functionalities in achieving maximum power point tracking (MPPT) and their implications on system cost, efficiency, and limitations. Further examination of gridconnected PV systems underscores the necessity for sophisticated inverter designs to ensure high efficiency, minimal harmonic distortion, and effective power management. Through MATLAB SIMULINK simulations, the paper evaluates the performance of solar PV systems equipped with different converter and inverter configurations, addressing the challenges posed by power fluctuations and the integration of solar energy into the grid. The research contributes to the ongoing discourse on renewable energy integration, presenting innovative solutions for grid synchronization, voltage regulation, and harmonic distortion reduction in solar PV systems.
