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. The DC power output passes through the power management moduleThe primary winding is supplied with high frequency alternating current through the inverter conversion of 2M active crystal oscillator.
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.
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 andCommon, in the packaging of many mobile phones and wireless chargers are often marked with Qi labels. 2, wireless charging is 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 the device that needs to be charged can be charged by contacting the wireless charging base.
3, 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 in the air between the charger and the phoneThe transmission load, coil and capacitor form a resonance between the charger and the mobile phone to achieve efficient transmission of electric energy technology.
4, now everyone uses a new way of mobile phone charging, that is wireless charging. So what is the principle of this wireless charger? Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
The basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field passesAfter air transmission, it is converted into current and transmitted to the intelligent terminal. 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.
Wireless charging source is installed inside a electromagnetic coil, after the power switch is turned on, the electromagnetic coil will convert the electric energy of the power supply battery into a large amount of magnetic energy, and then use a reverse coil (international standard brick QI coil) to receive this large amount of magnetic energy, and convert it into electrical energy through aMetal output heads are fed into our device reserve batteries. Wireless charging Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out.

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.

5, wireless charging principle: electricityMagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the transmitting coil generates a certain current in the mobile phone receiving coil based on the alternating current of a certain frequency through electromagnetic induction, thus transferring the electrical energy from the transmitting end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.

3Generally, wireless charging uses the principle of "current magnetic effect" and "electromagnetic induction". 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."
