Description

technical field [0001] The invention relates to a magnetic coupling electric energy wireless transmission system based on frequency control. In particular, it relates to a magnetically coupled electric energy wireless transmission system based on frequency adaptive control to optimize transmission power, high reliability, and good electromagnetic compatibility. 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...
