Abstract:

The increasing integration of renewable energy sources, such as solar photovoltaic and wind systems, into modern power grids necessitates highly efficient power conversion systems. DC-DC converters play a critical role in regulating voltage, improving energy efficiency, and ensuring stable operation of renewable energy systems. This study investigates the design, simulation, and optimization of high-efficiency DC-DC converters suitable for renewable energy applications. Advanced topologies, including buck, boost, and buck-boost converters, are analyzed for performance parameters such as efficiency, ripple voltage, thermal management, and load regulation. A combination of simulation using MATLAB/Simulink and experimental validation demonstrates that optimized converter design significantly enhances energy conversion efficiency while minimizing thermal stress and voltage fluctuations. The proposed methodology offers practical guidelines for engineers and researchers aiming to develop reliable and high-performance power electronic systems for sustainable energy solutions.
