2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, electromagnetic inductionA certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
4, the working principle of wireless charger: electromagnetic induction This is the most common way of working wireless charger, using the principle of electromagnetic induction, through the electromagnetic induction between the primary and secondary coils to generate current, so as to achieve the transmission of energy in the space laboratory wireless charging ; The implementation of this wireless charger has been promoted by the Wireless Charging Alliance.
5, wirelessCharging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it does not need 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 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 endSupply power directly to the system. 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, is based on the principle of electromagnetic inductionIt is not necessary to transfer electricity to the device with a transmission cable like a traditional wired charger, but to charge the device that needs to be charged by contacting the wireless charging base.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
