The rapid growth of renewable energy systems and electric mobility has increased the demand for efficient power conversion techniques. Bidirectional DC–DC converters play a crucial role in battery energy storage systems, electric vehicles, and microgrid applications by enabling controlled power flow between energy sources and storage units. This paper presents the design, modelling, and performance evaluation of a high-efficiency bidirectional DC–DC converter suitable for low-voltage renewable energy systems. The proposed converter employs synchronous switching and optimised control strategies to minimise switching losses and improve voltage regulation. Simulation and analytical results demonstrate enhanced efficiency, reduced ripple content, and improved dynamic response compared to conventional converters.
