Principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the coil is generated based on a certain frequency of alternating current through electromagnetic induction in the mobile phone receiving coilA certain current is generated, which transfers the point energy from the originating end to the receiving end, and begins to power the phone from the charging seat. Magnetic resonance.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
The principle of wireless charging is mainly electromagnetic induction and noLine electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
Because the energy is transmitted between the charger and the electrical device by inductive coupling, the two are not connected by wires, so the charger and the electrical device can be exposed without conducting contacts. Wireless charging mainly uses electromagnetic induction and magnetic fieldThe current generates a certain current in the receiving coil of the mobile phone through electromagnetic induction, so as to transfer the point energy from the originating end to the receiving end, and then start to supply power from the charging seat to the mobile phone. Magnetic resonance.

The QI standard is not just the distance between the twoApart, but both wireless charging when the frequency and communication protocol and other standards. This distance is a maximum distance, beyond which the efficiency of wireless reception is very low. So it doesn't have to be 8mm.
4, enamelled wire good. Due to the skin effect of the high-frequency signal in the wire, which means that the high-frequency current in the wire will converge to the surface of the wire, the wireless charging coil generally uses a multi-strand enamelled wire to reduce the impedance.
