Problems solved by technology

[0005] Electromagnetic resonance wireless power transmission was proposed by researchers at the Massachusetts Institute of Technology. Unlike the electromagnetic induction transmission used by the Qi standard, electromagnetic resonance transmission does not emit electromagnetic waves, but only forms a non-radiative magnetic field around it. , the strength is similar to the strength of the earth's magnetic field, and will not have adverse effects on the human body and surrounding equipment. Its effective transmission distance is tens of centimeters to several meters, but the entire electromagnetic resonance transmission device works in a high-frequency state, resulting in wireless energy transmission. less efficient

Abstract

The invention relates to a magnetic resonance wireless power transmission device, in particular to a magnetic resonance wireless power transmission device based on a PCB resonant coupling coil structure. The magnetic resonance wireless power transmission device comprises an input power supply provided with the output end, a high frequency emitting power supply provided with the input end and the output end, an electromagnetic resonance coil provided with the input end and the output end and a rectifying and load circuit. Compared with the prior art, an electromagnetic resonance emitting coil is identical with an electromagnetic resonance receiving coil, both the attenuation rate of the electromagnetic resonance emitting coil in a resonance bandwidth frequency and the attenuation rate of the electromagnetic resonance receiving coil in the resonance bandwidth frequency are reduced, and energy transmission efficiency is improved.

Description

technical field [0001] The invention relates to a magnetic resonance wireless power transmission device, in particular to a magnetic resonance wireless power transmission device based on a PCB resonant coupling coil structure. Background technique [0002] Traditional power transmission is mainly connected by wires, which is reasonable and effective under normal circumstances. In recent years, with the rise of mobile consumer electronics products that are full of "hungry" for power, such as tablet computers, mobile communications, and cameras, the demand for research and development of breakthrough charging technologies such as wireless charging is increasing. [0003] Wireless power transmission technology, also known as non-contact power transmission technology, was proposed by the famous Serbian-American electrical engineer and physicist Nikola Tesla as early as 1890. Using the principle of electromagnetic wave induction and related AC induction technology, a technology ...
