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 generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the deviceThe received energy is used to charge the battery and at the same time for its own operation.
Wireless charging principle is mainly electromagnetic induction and wireless 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.
A device that uses the principle of electromagnetic induction for charging has a principle similar to that of a transformerThe magnetic field 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 working principle of the wireless charger is mainly induced by magnets. When we place the phone in the inductive area of the wireless charger, the magnetic field generated by the magnet will generate an inductive current inside the phone. This current will pass through the phone's electricityThe circuit system generates voltage to charge the phone. Unlike wired chargers, wireless chargers transmit energy through magnetic fields rather than wires or cables. The key to this working principle is the establishment of magnetic fields.
