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.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils, and 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.
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 device uses the received energy to charge the battery, and at the same time for its own operation.
Wireless charging system mainly adopts the principle of electromagnetic induction. The wireless charger refers to the terminal that needs to be charged without the traditional charging power cord
