Abstract

The invention discloses an online charging method for a UAV based on multi-transmission and single-reception wireless charging. The receiver control module controls the receiver communication module to send a charging signal to the transmitter communication modules of multiple power supply drones, and the transmitter control module of the multi-power supply drone starts the transmitter flight control module according to the received charging signal, and According to the GPS dynamic positioning module of the transmitter, the multi-power supply UAV is roughly positioned under the power-receiving (operation) UAV, and the multi-power UAV realizes the precise alignment of the charging and receiving coils according to the principle of magnetic induction. To obtain the maximum load power as the goal, based on the equivalent circuit diagram of the precisely aligned multi-transmitting single-receiving system, the current value on each transmitting coil is optimized by circuit theory, and then the corresponding optimal voltage value of each feeding voltage source is obtained .

Description

technical field [0001] The invention relates to an optimal design method of a wireless power transmission system, in particular to an online charging method for an unmanned aerial vehicle based on multi-transmission and single-reception wireless charging. Background technique [0002] A century ago, Nicola Tesla proposed wireless power transfer technology based on magnetic coupling. With the maturity of power electronics technology in the field of high-frequency power supply, combined with the huge demand in today's applications, magnetically coupled wireless power transmission technology has achieved rapid development in recent decades. Especially since 2007, MIT scholars have made a major breakthrough based on the single-transmission and single-reception magnetic resonance wireless power transfer system, and magnetic resonance wireless power transfer has been extensively studied. [0003] From the perspective of transmission structure, the early structure of magnetic reso...
