Abstract

The invention provides a resonant coupling wireless power transmission system adopting a superconducting coil and an implementation method thereof. The resonant coupling wireless power transmission system comprises a high-frequency power source, a transmitting coil, a receiving coil and a liquid nitrogen container, wherein at least one of the transmitting coil and the receiving coil is made of high-temperature superconducting materials; the high-temperature superconducting coil is positioned in the liquid nitrogen container; and the high-frequency power source is connected with the input end of the transmitting coil. The implementation method provided by the invention can be used for making the transmitting coil and (or) the receiving coil by replacing the traditional common materials, such as copper wires and the like, with the high-temperature superconducting materials, thereby greatly reducing the internal resistance of the coils, greatly increasing the transmission power and efficiency, further lengthening the wireless power transmission distance and reducing the sizes of the coils and the resonant working frequency.
