As an electrical device for power conversion and power transmission, switching power supply provides the required power for various electrical and electronic equipment. At present, the demand for high-quality electric energy is increasing, especially for medical equipment, high-precision instruments, electrical and electronic equipment in buildings with relatively weak lightning protection measures. It is of great significance to study the power supply system with strong isolation from the power grid and provide high-quality electric energy for these equipment. In this paper, a small and medium-sized power supply system powered by a battery pack is designed. Combined with meteorological data, the lightning weather is judged, and the connection between the control charging circuit and the power grid is controlled. It can provide stable and high-quality power for small and medium-sized power electrical and electronic equipment, and is not affected by the grid side, avoiding the interference of the grid side and the impact of lightning strikes.
