Today to share the knowledge of the wireless charging coil lead diagram, which will also explain the working principle of the wireless charging coil, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>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, wireless charger is actually the use of electromagnetic induction principle for charging equipment, similar to a transformer, there is a coil at both ends of the transmit and receive, sendThe end coil is connected to the wired power supply to generate electromagnetic signals, and the receiving coil senses the electromagnetic signals of the sending end to generate current to the electrical equipment. As shown in the figure below, current flowing through the coil creates a magnetic field. The proximity of other unenergized coils to a magnetic field generates an electric current.
3, electromagnetic induction: simple and efficient close contact electromagnetic induction, like a pair of tacit understanding of the dancer, the sending end and the receiving end through the induction of magnetic flux transfer power. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and strict location requirements, requiring accurate alignmentBefore charging, as shown in Figure 4-1.
4, electromagnetic induction primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
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 24V direct currentThe terminal directly supplies power 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 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, 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.

Generally seen wireless charging, the use of the "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. What was further discovered was that by forming a loop around the wire,Even wound into coils, the resulting magnetic field will be stronger and more concentrated, which is called the "current magnetic effect."
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.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but to contact the device that needs to be charged with the wireless charging baseIt can be recharged.

The principle of wireless charging technology is "magnetic electricity", simply putIt is 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.

Basic principle: The use of electromagnetic induction, that is, 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 transfer energy from the transmission end to the receiving end.
Mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transfer charge in the air between the charger and the mobile phone, coil and capacitor form resonance between the charger and the mobile phone, to achieve efficient transmission of electric energy technology.
