Problems solved by technology

[0005] In the process of wireless power transmission, it is easy to change the resonant frequency due to the influence of external obstacles (such as magnetically permeable objects, etc.), the load of the receiving end and the operating temperature of the circuit, the change of the transmission distance, or the deviation of the angle. That is, misalignment, when the misalignment occurs, the efficiency will drop significantly

Description

technical field [0001] The invention relates to a novel magnetic coupling resonant wireless power transmission device. In particular, it relates to a novel magnetic coupling resonant wireless power transmission device with high robustness, high reliability and intelligence. Background technique [0002] Since it was discovered in 1840 that the use of electromagnetic induction and wires can transmit electric energy, the transmission of electric energy is mainly carried out by direct contact of wires. The charging of electrical equipment is generally carried out through plugs and sockets, but when high-power charging is performed, there is a risk of high-voltage electric shock in this charging method. And due to the existence of friction and wear, the safety, reliability and service life of the system are low, especially in some flammable and explosive fields such as chemical industry and mining, which can easily cause major accidents. The new contactless power transmission ...
