A High-Efficiency Wireless Power Transfer System for Unmanned Aerial Vehicle Considering Carbon Fiber Body

The application of wireless power transfer in the unmanned aerial vehicles (UAV) is becoming more and more extensive. In order to meet the requirements of miniaturization and lightweight, the fuselage of UAV often uses carbon fiber materials and the influence on the magnetic field distribution and energy transmission cannot be ignored. In this paper, the eddy current loss of the carbon fiber fuselage is simulated and analyzed, and the effect of the aluminum shielding method is studied. The study found that by optimizing the parameters such as the size, thickness and position of the shielded aluminum ring, the total system loss will be better improved, and the weight is light, which will not affect flight. Finally, a 500 W prototype is established to validate the method.
