Optimal Design of Magnetic Resonance Wireless Charging Coil for Unmanned Aerial Vehicles1

摘要

In this paper, an optimal design of magnetic resonance wireless charging coil for unmanned aerial vehicles (UAV s) is proposed to optimally design the structure of charging coupled transmitting coils and vehicle-carrying receiving coils for UAVs^{1. A parallel matrix double-layer coil superposition structure is adopted through transmitting coils and the size parameters of vehicle-carrying receiving coils are optimized to match the transmitting coil array, thereby ensuring a relatively high coupling coefficient between the receiving coils and transmitting platform when UAVs are located in any area of the charging platform, so as to improve the transmission efficiency of the UAV wireless charging system. The experiment results show that the transmission efficiency of the optimized designed coupled coil system can be kept stable with the horizontal movement of the receiving coils and transmitting coils.}
