Abstract

The invention discloses a wireless energy transmission system based on a magnetic resonance array, belonging to the wireless energy transmission field. A primary part in the system consists of a main power converter, a primary resonance capacitor, a primary magnetic induction coil and a primary magnetic resonance array. A secondary part consists of a secondary magnetic induction coil, a secondary resonance capacitor, a power controller and a secondary magnetic resonance array. Each one of the primary magnetic resonance array and a secondary magnetic resonance array consists of a plurality of magnetic resonance units; each magnetic resonance unit comprises a magnetic resonance coil and a resonance tuning capacitor; and the head ends and the tail ends of the magnetic resonance coils are respectively connected with both ends of the resonance tuning capacitors. In the wireless energy transmission system provided by the invention, the difficulty of an excitation frequency on selection is greatly reduced, the problem that the magnetic resonance coils are difficult to tune is solved, and the flexibility of the system utilization is improved.

Description

technical field [0001] The invention relates to a wireless energy transmission system, in particular to a wireless energy transmission system based on a magnetic resonance array. Background technique [0002] At present, wireless energy transfer technology has three research directions, namely microwave / laser wireless energy transfer, inductively coupled energy transfer and magnetic resonance coupled wireless energy transfer. [0003] Microwave / laser wireless energy transmission technology uses a microwave source or a laser source to convert direct current into microwave or laser, and then emits it from the antenna. The disadvantages of this technology are: the high-power radiation places extremely high requirements on the directionality of the transmitter, and the generated electromagnetic radiation / laser beams cause great harm to humans and animals. [0004] Inductively coupled energy transfer technology is to place two coils in adjacent positions, and when the current fl...
