The wireless power transmission device is used for energy supply of human body implanting equipment, portable mobile equipment and wireless sensor network nodes.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission. Background technique [0002] Wireless power transmission technology is a new type of power technology that realizes power transmission through non-physical media, and the magnetic coupling resonant wireless power transmission technology was first proposed by a research team at MIT and realized through an experimental device. light bulb. This technology has been valued by more and more scholars, and it has become possible to realize the power supply of long-distance small and medium power devices. [0003] Wireless power transmission methods are generally divided into three types: electromagnetic wave wireless power transmission, magnetic field induction wireless power transmission and magnetic coupling resonance wireless power transmission technology. For the third transmission method, the existing magnetic coupling resonant wireless power transmission technology mostly use...
