Abstract
To improve operational continuity during power outages, this paper proposes integrating a rechargeable battery backup system into smart airport lighting modules. This solution incorporates a lithiumion cell, a specialised linear charging circuit based on the MCP73831 integrated circuit and a diode-based power path management technique. The system is suitable for applications requiring a stable 5 V/1 A power supply. To guarantee reliable performance under varying input conditions, the system can easily be combined with an existing buck-boost converter. Simulation validation confirms stable output voltage, effective power source switching and adequate backup duration. This solution enables the development of smart lighting systems for vital airport infrastructure that are more resilient and self-sufficient.
