This work presents a power supply solution and energy management control for an all-electric hybrid energy storage system that integrates supercapacitors and batteries to enhance eVTOL endurance. The approach employs DC-DC converters to regulate power output from each source.. While electric unmanned aerial vehicles (UAVs) offer advantages in noise reduction, safety, and operational efficiency, their endurance is limited by current battery technology. Extending flight autonomy without compromising performance is a critical challenge in UAV system development. Previous. . The interest in electric unmanned aerial vehicles (UAVs) is rapidly growing in recent years. The reason is that UAVs have abilities to perform some di cult or dangerous tasks, with high mobility, safety, and low cost. It should be noted that UAVs are revolutionizing many public ser-vices including. . Electric vertical take-off and landing (eVTOL) aircraft have gained considerable interest for their potential to transform public services and meet environmental objectives. Designing an effective power supply for eVTOL is challenging due to the extreme power requirements during takeoff and. . In this paper, a novel fully-active PEMFC-Lithium battery hybrid power system is designed for UAV applications. The proposed construction employs an automatic ON/OFF switch in parallel with a DC-DC converter to control the PEMFC and a second automatic ON/OFF switch replacing the commonly used DC-DC.
