Abstract

The invention provides a wireless energy transmission system. A first metamaterial is fixedly installed at the rear end of a magnetic resonance transmitting module, a second metamaterial is fixedly installed at the front end of a magnetic resonance receiving module, both the first metamaterial and the second metamaterial have negative magnetic conductivity, and therefore efficiency of energy transmission of the whole wireless energy transmission system is improved. As for the whole wireless energy transmission system, the distance of energy transmission is long, equipment at the receiving end does not need to be attached to the transmitting end, energy transmission can be achieved, the degree of using freedom of the loading equipment at the receiving end is improved greatly, and convenience is brought to users. According to the design of the metamaterials, microstructures of the metamaterials are designed to be multiply-nested split resonant rings or derived structures of the split resonant rings in a multiple winding mode. On one hand, the resonant frequency of the metamaterials can be regulated by means of the number of turns of a winding; on the other hand, the resonant frequency can be greatly reduced, influences, on the environment, from the wireless energy transmission system can be reduced, and safety performance is improved.

Description

technical field [0001] The invention relates to the field of wireless energy transmission, in particular to a wireless energy transmission system based on the principle of magnetic resonance. Background technique [0002] At present, wireless energy transmission technology is mainly based on three principles, namely electromagnetic induction, magnetic resonance and radiation. The basic feature of electromagnetic induction (non-contact inductive) power transmission circuit is the separation of primary and secondary circuits. There is a gap between it and the secondary circuit, which is connected by magnetic field coupling induction. The characteristics of the electromagnetic induction type are: there is a large air gap, so that the primary and secondary sides have no electrical contact, which makes up for the inherent defects of the traditional contact type electric energy; however, the existence of a large air gap also makes the magnetic flux leakage of the system comparable...
