Unmanned Aerial Vehicles (UAVs) technology has seen a significant boost in the past ten years and has been widely adopted in entertainment, rescue, intelligent transportation, notouch delivery, environmental monitoring and other real world applications. However, the ranging limitation due to the shortage of battery energy capacity remains a major issue hindering further development of UAVs. Wireless power transfer (WPT) technology is a new technology of great potentials in improving the endurance of UAVs. The integration of WPT into UAV not only activates the recharging of UAVs batteries, but also enables UAVs to recharge other devices. Moreover, wireless charging technology allows the device to be fully enclosed and suitable for harsh weather conditions. This paper presents a comprehensive review in regard to the state-of-the-art of nearfield WPT technologies for UAV charging, including technologies characteristics, design issues, as well as multiple case studies. A comparative analysis of existing technologies are also presented, associated with key future research discussions of WPT for UAVs.

Inductive power transmission technology provides a new way to solve the energy problem of autonomous underwater vehicles (AUVs). The performance of the magnetic coupler determines the system transfer capacity. A novel open-type magnetic coupler with a simple structure, lightweight, strong anti-misalignment performance and high self-inductance stability is proposed for the arc-shaped shell of AUV. The proposed magnetic coupler employs an arc-shaped transmitter and the receiver uses an H-shaped ferrite core to realize the close coupling of magnetic flux in the vertical direction. The parameters of the magnetic coupler are optimized based on ANSYS Maxwell simulation, which ensures its coupling performance and anti-misalignment performance while minimizing the volume and weight of the receiver. To verify the proposal, a wireless charging system with a 183.9 g receiver is built. The maximum self-inductance change rate of the coil and maximum coupling coefficient change rate under the conditions of axial misalignment from −25 mm to 25 mm and rotational misalignment from −10 • to 10 • are 2.9% and 14.3%, respectively. In the case of full alignment, it can deliver 735.6 W at a DC-DC efficiency of 90.87%.

“…However, the single-coil design of this structure is too complicated, and the energy loss is relatively large. The orthogonal coupling structure proposed in [20] mounts the receiver coil on the UAV's leg without occupying the gimbal position and achieves a UAV wireless charging system with 500 W charging power that is also lightweight and has low magnetic leakage interference. However, the lateral area of this receiver coil is too large and not fully embedded in the UAV's leg, making it highly susceptible to damage when landing.…”

This paper proposes an orthogonal concave coupling mechanism based on wireless charging for unmanned aerial vehicles (UAVs); the original edge adopts a concave transmitting coil. So as not to occupy the gimbal position at the receiving end, the receiving coil is installed on the landing gear of the UAV perpendicular to the transmitting coil to form an orthogonal coupling magnetic field. This study conducted a finite element simulation of the coupling mechanism using Ansys Maxwell to test the mechanism’s coupling capability and anti-offset performance. The spatial distribution of the system’s magnetic field was constrained, and the magnetic flux leakage of the system was reduced by optimizing the transmitter structure. The system employed a double-sided LCC compensation topology network and used wireless communication to achieve constant voltage/constant current closed-loop control. Finally, the experimental platform was built, and the results show that the system output power was able to reach 960 W with 85.7% efficiency, and could realize the closed-loop control of charging with 48 V constant voltage and 20 A constant current. The system has the advantages of being small in size, lightweight (290 g) and easy to install, and the receiver device has strong resistance to offset.
