International Journal of Power Electronics and Drive Systems (IJPEDS), 2022

This paper presents an alternative approach to power up unmanned aerial vehicle (UAV) system using inductive approach. The main issue of utilizing UAV in any application especially in precision agriculture is the lifetime of the battery. This limits the flight time of the UAV which makes the system is unable to be efficiently applied for precision agriculture purpose. Hence, this paper proposes a new approach of powering UAV system by using so called inductive power transfer (IPT) technology. Through this approach, the system can be powered up wirelessly with no physical link in between transmitter and receiver. To be specific, class E inverter circuit has been designed together with impedance matching circuit to ensure higher efficiency is obtained. Finally, a prototype of IPT system for powering up the UAV system was successfully developed, which is able to transmit 23.32 W of power at 1 MHz operating frequency from 12 V input supply. The system achieved up to 95.73% efficiency.

UAV Recharging Using Non-Contact Wireless Power Transfer

This paper proposes application of Unmanned Aerial Vehicles (UAV)s for infrastructure inspection, such as power lines and support towers, where energy for the UAV could be gathered from the green sources, or collected from electromagnetic fields generated around the power distribution lines. This type of UAV application could, also, include monitoring buildings, agriculture areas, or water processing plants, where solar energy could be utilised. The proposal in this paper is focused on inductive and resonant inductive couplings. The concept of powering UAV, while inspecting high voltage power lines, is based on energy harvesting from electromagnetic field, at close vicinity of the conducting wires. The entire power line is acting as an infinitely long antenna.

Design of a Recharge Station for UAVs using Non-Contact Wireless Power Transfer

Power infrastructure inspection is a requirement task to assure proper functioning of its distribution. Comparing to current practice, this task can be performed by safer and more economical alternatives, like the application of electrical UAVs. The main problem with this type of vehicles is the low endurance/range capabilities due to the high expend rate and the batteries characteristics. This research proposes a possible way to achieve longer distances and flight times by means of wireless recharging. We made the study and preliminary design of a strongly coupled magnetic resonance (SCAR) system that can be located inside the current infrastructure and that can transmit electric power to the UAV for battery recharge.

Wireless Far-field Charging of Quadcopters: WPT System

Graduate Research in Engineering and Technology

In this study, wireless power transfer using a transmitting horn antenna and receiving module is designed and analyzed. The receiving module comprises transmitting (horn) and receiving antennas, rectifier, and power management unit. The receiving antenna is used at a frequency of 2.45 GHz which seems to be the most efficient one. The integrated system being low in weight is suitable to be placed on any system having a battery with recharging characteristics. The compact system is designed and simulated using CST STUDIO. The receiving module is used for the conversion of microwave power to DC power for the easy charging of a Quadcopter. Drones always carry a minimal amount of payload and hence require a low weight power receiving system. The integration of 3 by 4 antenna array with the power management circuit makes it of minimal weight which is effective for UAVs. The distance taken into consideration is from 1 to 6m which works in relation to the power transmitted. Far-field transf...

Simulation and Control Design of a Midrange WPT Charging System for In-Flight Drones

Energies

Drones, or unmanned aerial vehicles (UAVs), have emerged as an indispensable tool across numerous industries due to their remarkable versatility, efficiency, and capabilities. Notwithstanding all these traits, drones are still limited by battery life. In this paper, we propose a genuine in-flight charging method without landing. The charging system consists of three orthogonal coils, among which the receiving coil is connected to the drone. The development of the model for wireless dynamic charging systems is achieved by integrating the receiver trajectory and velocity in the model. Furthermore, the model is significantly enhanced by introducing the concept of the positioning mutual coupling function for the receiver trajectory; thus, it is possible to simulate a genuine continuous trajectory for UAVs and link it to the systems’ total input power consumption. The developed control algorithm can direct the magnetic field resultant to track the exact trajectory of the drone. The real-...

Short Range Wireless Power Transfer (WPT) for UAV/UAS Battery Charging - Phase 1

2014

: The inductive and radiative approaches to wireless power transmission (WPT) were simulated using commercial software. For the inductive approach, working at 100 kHz, efficiencies over 90% were obtained at short ranges (less than 30 mm) utilizing ferrite plates. For the radiative approach, the transmission loss between antennas was less than 1 dB at ranges less than 3 m when near field focusing was employed. The results for the two approaches are important because they demonstrate that efficient transmission of energy for battery charging can take place between a WPT ground station and client.
