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 system mainly adopts 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, and uses the latest noWire charging technology, through the use of magnetic fields generated between the coils, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and equipment.
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.
Generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."

Wireless charging is also known as inductive charging or non-contact inductionCharging, based on the principle of electromagnetic induction, does not require a transmission cable to transmit electricity to the device like a traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
The principle of mobile phone wireless charging is as follows: the electromagnetic induction charging base and the mobile phone terminal have built-in coils respectively. When the two are near, the transmitting coil generates a certain current in the receiving coil based on a certain frequency of alternating current through electromagnetic induction, thus transmitting electrical energy from the mobile phoneThe end is transferred to the receiving end, and power is supplied to the phone from the charging seat.
Wireless charger working principle: electromagnetic induction This is the most common wireless charger working mode, using the principle of electromagnetic induction, through the primary and secondary coil between the electromagnetic induction to generate current, so as to achieve the energy in the space of the transfer; The implementation of this wireless charger has been promoted by the Wireless Charging Alliance.
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, by using the magnetic field generated between the coils, magicThe inductive coupling technology will become the bridge connecting the charging base station and the equipment.
3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
