3, the basic principle of wireless charging, that is, the electricityThe flow is converted 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.

Electromagnetic induction type wireless charging, when the power supply of the current through the coil (wirelessThe charger's power supply coil) will generate a magnetic field, and other unenergized coils (the phone's receiving coil) will generate current near the magnetic field to charge the phone. As shown below.

4, 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.

1, wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive inductive current to charge.
2, the test results show that the wireless transmission distance is about 15 cm, but Fujitsu said that the wireless transmission distance is the mostEventually it can be achieved a few meters. It should be pointed out that the further away from the device, the more power lost in transmission. Fujitsu's system is similar to technology developed by Witricity, an American company, which also uses magnetic resonance to transmit electricity over distances of several meters.
3, the principle of wireless charging technology is electromagnetic induction, magnetic field resonance, radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.

This way the transmission distance is greater than 10 meters, which is suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. WiFi wireless charging. It mainly consists of two components, one is a Wi-Fi access point (router), and the other is a customized charging sensor.
5, currently known reports, the farthest distance is 10 meters, the use of electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technique mentioned aboveThe technique, using electromagnetic waves as a medium, is currently in the laboratory stage. At present, the commercial technology on the market is mainly magnetic field as the medium, which is divided into magnetic induction and magnetic resonance 2 technologies.

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."

After charging the battery and passing through the power management module, the DC output is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding. By coupling the energy of the two inductors, the electrical output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery.
