Abstract

The invention discloses a magnetic coupling resonant wireless power transmission system based on an electromagnetic metamaterial. The system comprises a high-frequency power supply, a first power detection module, a first communication module, a transmitting coil, a metamaterial coupling degree adjusting device, a receiving coil, a second power detection module, a second communication module, a load, an efficiency and power calculation module and a motor control and drive module. According to the invention, the position of the metamaterial coupling degree adjusting structure can be adjusted according to the transmission efficiency and the transmission power, so that the provided magnetic coupling resonant wireless power transmission system based on the electromagnetic metamaterial can obtain the maximum transmission efficiency or the maximum transmission power.

Description

technical field [0001] The invention relates to the technical field of magnetic coupling resonant wireless power transmission, in particular to a magnetic coupling resonant wireless power transmission system based on electromagnetic metamaterials. Background technique [0002] The magnetically coupled resonant wireless power transfer system realizes the energy transfer between the transmitting coil and the receiving coil by coupling the evanescent wave in the near field. It has the characteristics of high efficiency, safety and convenience, and has received extensive attention at home and abroad. However, when the transmission distance increases, the transmission efficiency of the system will drop sharply, which greatly limits the practical application of magnetic coupling resonant wireless power transmission. Placing electromagnetic metamaterials in a magnetically coupled resonant wireless power transfer system can effectively improve the magnetic field distribution between...
