Electromagnetic induction type primary coil a certain frequency of alternating current through electromagnetic induction in the secondary lineA certain current is generated in the loop, which transfers energy from the transmitting end to the receiving end.
The principle of wireless charging of mobile phones in a general sense is the process of converting electrical energy into a magnetic field, which is transmitted through the air, and then converted into electrical energy. The principle of wireless charging is somewhat similar to the understanding of the transformer in the popular sense, the transformer magnetic field coupling circuit is a magnetic conductor, the wireless charging magnetic field coupling circuit is air, and the magnetic medium is different. Wireless charging in the industry generally has four major technologies: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology.
The above is the schematic diagram, the principle usedProximity to the magnetic field generates an electric current that charges the phone.
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, 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 then converted into a current to be transmitted to the intelligent terminal. Input when the system is workingThe AC mains is converted into direct current through the full bridge rectifier circuit, or the 24V DC terminal is used to supply 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.
4, there is no strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.

3, 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."
4,The principle of wireless charging technology is "magnetic electricity", which is simply through the charging device and the two "magnetic equipment" installed on the mobile phone device to induce each other and form a 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.
5, wireless charging 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 cable like the traditional wired chargerInstead, the device that needs to be charged can be charged by touching the wireless charging base.
