There are three main wireless charging schemes: electromagnetic induction, magnetic resonance and radio wave. First of all, electromagnetic induction wireless charging is the most widely used scheme at present. Its principle is similar to that of a transformer, which generates a magnetic field through the coils at the sending and receiving ends to achieve wireless transmission of electrical energy. This way the charging efficiency is higher, but the transmission distance is relatively short, usually within a few centimeters.

vivo mobile phone support wireless charging inventory vivo X60 Pro This mobile phone was quickly welcomed by usersWelcome, because it not only supports wireless charging, but also supports fast wireless charging. It is equipped with the latest mobile phone chips, excellent performance, and has an ultra-high-definition screen and efficient power consumption. Its wireless charging feature can also support reverse charging, allowing its users to use their phone to charge someone else's phone.
2, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and 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.
3. No electromagnetic inductionLine charging: This way of charging is to use the inductive magnetic flux generated between a wireless charging board and the induction magnet on the mobile phone, and convert this magnetic force into an electric power for current transmission.
4, 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.
1, the principle of electric field coupled wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
2. NoneThe basic principle of wire 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.
3, electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to energyFrom the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
4, wireless charging technology from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways, its principle is through near-field induction, by the wireless charging device will be transferred to the charging terminal device, the terminal device will receive the energy into electricity stored in the battery of the device. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones.
5, the main principle of wireless charging is electromagnetic inductionIt begins to power the phone from the charging seat. Magnetic resonance.
