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.

Description

technical field [0001] The invention belongs to the application field of wireless power transmission or non-contact power transmission, and relates to a resonant coupling wireless power transmission system using a superconducting coil and a realization method thereof. Background technique [0002] As an emerging power transmission technology, wireless power transmission technology has the advantages of safety, reliability, flexibility and convenience. Places, such as implanted medical devices, mobile electronic products, robots, railcar power supply, etc., are expected to replace traditional plug charging in the wireless charging of low-power electronic products in the near future. [0003] Resonant coupling wireless power transmission requires that the transmitting coil and the receiving coil have the same natural frequency, so it can realize efficient wireless power transmission in all directions without being affected by space obstacles within a medium distance range. Th...
