Abstract This composition portrays the verification of applied research for increment in the flight time of an unmanned aerial vehicle (UAV) utilizing a hybrid electric propulsion system (HEPS) comprised of a solar cell, lithium-ion polymer battery, and supercapacitor bank. The implementation of a hybrid power supply comprised of both lithium polymer batteries having high specific energy (Wh/kg) and supercapacitors with high specific power (W/kg) with the additional option of solar charging was funded to be the optimal approach. High thrust requirements can be fulfilled by solar charging and a lithium polymer battery working in parallel with a proper conversion unit. The rapid charging potential of the supercapacitor helps to fulfill the power requirements of the UAV during flight time. Real-time experiments with special consideration were conducted to examine the increase in flight time of the UAV with the proposed HEPS. Very small and lightweight voltage regulation circuits were used to reduce the payload of the UAV and avoid unnecessary power consumption to achieve extra thrust. Simulations (MATLAB/Simulink) and experimental analysis were performed for a Phantom II DJI under different operating conditions. The effectiveness of the proposed HEPS was also validated.

1 Introduction Unmanned aerial vehicles (UAVs) are useful in a range of applications, including monitoring woodlands, data gathering for military surveillance, and media coverage. The long-term endurance of a UAV is important for achieving the desired tasks effectively. Several techniques to increase the flight time of UAVs have been proposed. One innovation with potential is the utilization of a hybrid electric propulsion system (HEPS) [1]. Hybrid innovation incorporates upsides of at least two sources of power to deliver a progressively proficient vehicle propulsion system. At the same time, numerous variations of hybrid frameworks are accessible now; mostly we derived it

from three fundamental classifications: series, parallel, and power split. Even though the maximum system put to use an inward combustion or burning engine as the essential power source, others may utilize a turbine engine or fuel cell. Every framework has some uncommon favorable circumstances and hindrances that can be versatile to the needs of the vehicl
