The basic principle of wireless charging mobile phone wireless charging coil , that is, the current is converted into a magnetic field Mobile phone wireless charging coil , and the magnetic field is transmitted through the air and converted into current 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 the power management module output mobile phone installed wireless charging coil direct current through 2M active crystal inverter into high frequency alternating current supply primaryThe 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 itDeflect the compass needle. 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."
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. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger transmission coil) will generate a magnetic field, the mobile phone installed wireless charging coil he is not energized coil (mobile phone end of the electric coil) closeThe magnetic field generates an electric current that charges the phone. As shown below.
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.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the airSelect the appropriate coil. The Mi 11 wireless charging position is in the middle of the back cover of the phone. The device with wireless charging function conforming to the Qi standard is placed in the center of the wireless charger, and the charging will automatically start.
In the central position on the back of the phone, the specific position can see the Xiaomi Logo on the back of the phone, the wireless charging coil is on the position below it. When you use a wireless charging board to wirelessly charge the Mi 11Ultra, simply align the wireless charging coil on the back of the phone with the charging board to charge it. Mi 11ultra wireless charging coil position Mi 11ultra Wireless charging coil position In the mobile phone Settings page, Mobile phone wireless charging coil We click to enter the column of battery and performance.
The back cover of the phone. He is on the back cover of the phone, the same as the wireless charging coil of most mobile phones. It can be said that the induction coil of most mobile phones for wireless charging is basically in the back cover, and will not be placed in other positions, because the top of the phone will also put nfc.
Wireless charging coil in the backplane, transparent back cover, you can see the position of the coil. Xiaomi has built in 19 coils, each of which supports 20W wireless charging, and can choose the appropriate coil according to the placement of the product. Therefore, whether it is placed vertically, horizontally or diagonally, the millet multi-coil wireless fast charging board can almost achieve pairing and charging.
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 the device that needs to be charged can be charged by contacting the wireless charging base.

Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
The principle of mobile phone wireless charging is as follows: the electromagnetic induction charging base and the mobile phone terminal are respectivelyWhen the coil is placed, when the two are close, the transmitting coil generates a certain current in the receiving coil of the mobile phone based on a certain frequency of alternating current through electromagnetic induction, so as to transfer the electrical energy from the transmitting end to the receiving end, and begin to supply power to the mobile phone from the charging seat.
1, the back cover of the mobile phone. He was on the back cover of the phone where the wireless charging coil is located, the same as the wireless charging coil on most mobile phonesIt can be said that the position of the induction coil for wireless charging of most mobile phones is basically in the back cover mobile phone wireless charging coil , and it will not be placed in other positions mobile phone wireless charging coil , because the top of the phone will also put nfc.
2. On the back of the phone. The Mi 13 wireless charging is located on the back of the phone, the same as the wireless charging coil on most mobile phones. Most mobile phone wireless charging induction coil position is basically in the back cover Mobile phone wireless charging coil andYou won't put it anywhere else, because you'll still have nfc on the top of the phone. Middle of the back of the phone.
3, in the central position on the back of the phone, the specific position can see the Xiaomi Logo on the back of the phone, the wireless charging coil is on the position below it.

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."
1, plug the wireless charging receiving coil into the phone interface, just like the usual charging. Plug in the receiving coil. Connect the Qi wireless charging and transmitting device and then plug the charging head into the wall socket, and then connect the Qi wireless charging and transmitting device to the other end of the data cable. All the work is ready, the phone is placed on the wireless transmitter, can also be held in the hand, in the effective receiving range can beYes. The exact extent needs to be tested by oneself.
2, prepare an Apple AirPower wireless charging pillow. Connect the Apple wireless charger AirPowe to a power source. Place the iPhone8 on the wireless charger AirPowe with the iPhone8 display facing up and the phone will charge itself.
3. First get an iphone8. Get a wireless charger. Connect the wireless charger to the power supply. Place the iphone8 on the sensor area of the wireless charger. You can see the phone start chargingWait patiently for the charging to complete.
