Abstract :
To create reliable and effective renewable energy systems, photovoltaic (PV) systems must be integrated with energy storage devices like batteries. To maximize energy transfer between the PV array, the battery, and the load, a high efficiency DC/DC converter is essential. The design of a high efficiency LLC resonant DC/DC converter specifically suited for photovoltaic battery systems is presented in this work. Because of its built in benefits of soft switching and zero voltage switching (ZVS), which greatly lower switching losses and electromagnetic interference (EMI) and increase system efficiency, the LLC converter was selected. A thorough examination of important factors such resonant tank design, control strategy, and efficiency optimization techniques is part of the suggested converter design. According to simulation studies, the converter is well suited for dynamic PV situations since it can provide excellent power conversion efficiency over a broad input voltage range. Additionally, the converter achieves fast transient response and excellent load management, which provide dependable battery charging and discharging while preserving system stability. It is demonstrated that the suggested solution significantly increases system dependability, efficiency, and thermal performance, providing a viable strategy for contemporary PV battery integrated systems.
