1, the basic principle of wireless charging is to convert the current into a magnetic field, which 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.
2, wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
3, 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, magical transmission of electric energy, inductive coupling technologyThe technology will be a bridge between charging base stations and devices.
4, the use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil to receive electromagnetic signals and electromagnetic signals into current, so as to achieve the purpose of wireless charging.
5, if the use is vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized. 2, if the use is vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized. 3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones is mostly usedPrinciple of electromagnetic induction. 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. Please ask the gods, what harm or change will the wireless charging base increase coil?
1, wireless charging base to increase the coil, or do not modify it, you increase the coil not only did not play a good effectAnd affect the speed of charging, increasing the coil is equal to increasing the resistance, it will make the current slow, the coil is proportionally wound, too much or too little can not, coil wound less, there will be damage to the parts, resulting in parts burned spark, because do not be free to modify the wireless charging base.
2, wireless charging will not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Cell phones have secondary coils built into them. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and the load is generated after productionGenerate an induced current to charge the phone. So don't worry.
3, can not, excessive increase in voltage or increase the number of turns will burn the battery, because the more you turn the higher the voltage, I do not know whether your self-made charger is Qi program, if it is Qi, it is not possible, this must be close contact, you have to change to radio wave type, within five meters.

1, millet multi-coil wireless fast charging board can charge the iphone From the official release of the opening poster, millet's multi-coil wireless fast charging board can give the Apple model wireless fast charging. This fast charging board can charge up to three devices at a time, in addition to charging mobile phones, it can also charge Bluetooth headphones that support wireless charging.
2, in summary, the millet multi-coil wireless fast charging board can be perfect for wireless charging of the iPhone. As long as your iPhone supports wireless charging, you can confidently use Xiaomi's wireless charger to charge.
3, this 10W universal fast charging version supports QC protocol, suitable for most wireless charging devices, for iPhone 8 users like me, although it is enough, but after upgrading to IOS11, wireless charging speed has decreased. Android users will need a higher power version, as more than 18W is needed to fully meet demand.

The principle of wireless charging is through near-field induction, wireless chargingThe device conducts the energy to the charging terminal device, which converts the received energy into electricity, which is stored in the device's battery. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
