Abstract

The invention discloses an electromagnetic resonance coupling type wireless charging efficiency optimization method suitable for an unmanned aerial vehicle. The method comprises the following steps: 1, designing a wireless charging platform of the unmanned aerial vehicle; 2, establishing an equivalent circuit model of coil wireless charging; 3, determining the radius of a transmitting coil; 4, determining the number of turns of the transmitting coil; 5, optimizing the number of turns of a receiving coil; 6, optimizing the radius of the receiving coil; 7, optimizing the resonant frequencies ofthe transmitting coil and the receiving coil; 8, optimizing the distance between the transmitting coil and the receiving coil; and 9, performing non-coaxial optimization on the wireless power transmission efficiency of the transmitting coil and the receiving coil. The radius of the transmitting coil is determined as large as possible under the condition that the anti-interference distance is reserved, the diameter and the number of turns of the receiving coil are optimized according to the coupling relation between the transmitting coil and the receiving coil, the radius of the receiving coilis determined as small as possible under the condition that the magnetic field density is guaranteed, the resonant frequency, the distance and the non-coaxiality of the two coils are further optimized, and the wireless charging efficiency of the unmanned aerial vehicle is maximized.
