Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a method and device for optimizing structural parameters of a wireless charging magnetic coupling device. Background technique [0002] UAV (Unmanned aerial vehicle) has the advantages of high flexibility, and has been widely used in many fields such as reconnaissance, survey, agriculture, inspection and so on. However, due to the limitation of the UAV's own load capacity and volume, the capacity of the battery is limited, and the line charging technology can safely, reliably and efficiently supply UAV with power. [0003] As a key component in the wireless charging system, the magnetic coupling device determines the power transmission capability and efficiency of the wireless charging system. However, the current research on wireless charging technology mainly focuses on the circuit topology, impedance matching and control strategies, and there are few studies...
