This article to talk about wireless drawing, and wireless charger production drawings corresponding knowledge points, I hope to help you, don't forget to collect this site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, SeekSimple mobile phone wireless charger circuit diagram or schematic diagram and schematic analysis
Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission 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 in the popular sense of understanding is somewhat similar to the transformer, the transformer magnetic field couplingThe circuit is a magnetic conductor, and the circuit of wireless charging magnetic field coupling is only 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 used is the principle of electromagnetic induction.
Wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive the induced current to charge.
Mobile phone wireless charging is a relatively novel charging method, the principle is actually very simple, that is, the ordinary transformer primary and secondary pointsOpen to achieve the purpose of wireless. Of course, the working level of wireless charging is relatively high, and even the role of energy transfer can be achieved between the iron core and the direct coil can be abandoned. Drawings to there are a lot, but will not send pictures, to tell you about the simplest wireless charging.
The principle is very simple, that is, electromagnetic induction, but the actual wireless charger must be more complex, because it needs supporting program functions, such as foreign body detection, temperature control, frequency conversion and so on. If you just play with the test, get two coils of the same specification (different can also be, but the voltage will change), one input 5V AC power into the other connected to the mobile phone charging portI can charge it, but I'm sure it's inefficient.
Mobile phones use wireless charging, you need to buy a wireless charging base or wireless charging back case to use. Connect the charger to the wireless charging base, and then place the phone or a phone with a wireless charging back case on the wireless charging base. Take off the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to take off the holster and try charging.
Some of Huawei's high-end mobile phones in addition to supportSuper wired fast charge can also support wireless charging, the use of wireless charging requires a separate wireless charger. How to use Huawei wireless charger? Connect the charger (the charging tip that came with your phone or was purchased separately) to a power source. Connect the data cable Connect the charger to the wireless charger using the data cable. Place the phone Place the rechargeable area of the phone in the center of the upper surface of the wireless charger, and the phone shows that it is charging.
Place the phone on the charger Finally, place your Mi 11 on the charger, making sure the two fit tightly. If the words "Charging" appear on the screen, wireless charging is started. Don'tForget, the power plug of the charger should be connected to the socket, and the distance from the mobile phone should not exceed 5mm! Wireless charging Tips Wireless charging is convenient and fast, but it also requires attention to safety.
How to use the HONOR 100pro Wireless charging I think the HONOR 100pro wireless charging can be used like this: on a smooth surface. Place the phone on the charging area. Make sure the phone is in contact with the wireless charger. Plug the charger into the socket.
The correct way to use the wireless charger: Connect the charger to the power supply. Please use the charging head, charging cable and wireless charging base purchased by yourself. Will fillElectrical appliances are placed on a horizontal surface or other location suggested by the manufacturer. Place the phone on the charger with the screen facing up. For best performance, place the phone in the center of the charger or in the location recommended by the manufacturer.
If your mobile phone supports wireless charging, charge it directly by placing the mobile phone screen facing up in the center of the charger or the position suggested by the manufacturer after the wireless charger is powered.
Open oppofindn2 mobile phone. Click "Settings" to enter the setting interface. Click "Wireless reverse charging", click the open button to wireless charging.
Enter the "Set other Settings OTG connection" and turn on the switch; Note: ColorOS 12 and above: "Set System Settings (convenient tool) OTG connection" Insert a dual-head USB cable that supports reverse charging or an OTG adapter USB cable to connect two mobile phones to charge.
Turn on the switch on the right of [Wireless reverse charging]. Put the two phones back to back togetherYou can reverse charge. oppofindx3 How to turn on wireless charging? In your phone's Settings menu, tap Battery. Turn on the switch on the right of [Wireless reverse charging]. You can click [Wireless Charging Settings] to set the silent mode.
< br > Set path: < br > Set wireless battery reverse charging. < br > Note: < br > The charged device needs to support wireless charging.
You can also choose to customize the silence time. Open Settings and tap Battery; On the battery page, tap Wireless charging Settings; The function will always be on. noteTry charging after dropping the holster.
