Abstract

The invention discloses an unmanned aerial vehicle wireless charging system with a position capturing function, belongs to the technical field of wireless power transmission, and aims to solve the problem that the power transmission efficiency is affected due to the fact that the coupling coefficient between a primary coil and a secondary coil changes along with position deviation between the primary coil and the secondary coil in the existing wireless power transmission. The input end of a full-bridge inverter circuit is connected with an input power supply, the output end of the full-bridgeinverter circuit is connected with a primary side coil of a loose coupling transformer through a primary side compensation topology, a secondary side coil of the loose coupling transformer is connected with a rectifying and filtering circuit through a secondary side compensation topology, and the output end of the rectifying and filtering circuit is connected with an unmanned aerial vehicle charging load; a current sampling circuit is used for collecting input end current of the full-bridge inverter circuit and transmitting the input end current to a DSP controller; and the DSP controller provides a driving signal for the full-bridge inverter circuit and controls the on-off switching of the primary side coil. The unmanned aerial vehicle wireless charging system is used for unmanned aerialvehicle load charging.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle wireless charging system with a position capturing function, and belongs to the technical field of wireless energy transmission. Background technique [0002] Due to the limitations of current battery technology, it is impossible to carry large-capacity batteries on UAVs that require flexibility and miniaturization. However, the traditional contact-type wired charging method has the disadvantages of complicated operation and short service life, and there are also potential safety hazards when used outdoors. [0003] Wireless power transmission technology can transmit electric energy without the use of metal cables and other media. It has the advantages of electrical isolation, convenience and safety, and it effectively solves various problems existing in wired power transmission. At present, wireless power transmission technology has been widely used in high-power wireless charging of electric vehicl...
