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.
Hand in the general senseNeed to buy their own, the official mobile phone is not sent wireless charger, take out the purchase of wireless charger. Wireless charger is the need for external power, plug the charging head into the socket. Hold the iPhone8 in range of the wireless charger with the screen up and the back down. You can see that the phone starts to charge, and wait for the charging to complete.
Apple 8 is a very advanced mobile phone, it has wireless charging function, users only need to put the phone on the charger that supports the Qi standard, you can achieve wireless charging. Let's take a look at the specific operation method. First, you need to prepare oneSupport Qi standard wireless chargers, such as Apple's official recommended AirPower wireless charging board or other manufacturers compatible with Qi standard chargers.
Wireless charging first depends on whether it is contact or non-contact. The disadvantage of contact wireless charging is also obvious, that is, the mobile phone must be placed on a dedicated charging board, although the step of inserting the data line is omitted, but the charging board will stop charging, so in essence, it is still wired charging. Non-contact can be charged without a data cable within a certain range. Prepare the accessories needed for charging, wireless charger, wireless charging receiverA coil.
The iphone8 uses a wireless charger to charge the phone as follows: Get an Apple AirPower wireless charging pillow, as shown in the image below. Connect the Apple wireless charger AirPowe to a power source, as shown in the image below. Place the iPhone8 on the wireless charger AirPowe with the iPhone8 display facing up and the phone will charge itself.
Connect your Apple wireless charger to a power source. Place the iPhone8 on the wireless charger to make the iPhone8 displayScreen facing up. The iPhone8 will start charging a few seconds after you put it on a wireless charger, and the iphone8 will be charged using a wireless charger.
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. 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 energy with two inductors, the electrical output of the secondary coil flows through the received converted electricityThe circuit changes to direct current to charge the battery.
Wireless charging source is installed inside a electromagnetic coil, after opening the power switch, the electromagnetic coil will convert the power supply battery into a large amount of magnetic energy, and then use a reverse coil (international standard brick QI coil), receive this large amount of magnetic energy, convert it into electrical energy, through a metal output head, into our equipment reserve battery. Wireless charging Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger means no transmissionThe charging power line is connected to the charger on the terminal device that needs to be charged, using the latest wireless charging technology, by using 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 the device.
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.
No strong radiation, no effect on the human body! The main principle isWireless 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.
This is the end of the introduction of wireless charging transmission and reception schemes and how to use wireless charging transmitters. Do you know if you can find the information you need? If you want to know more about this, remember to follow this site. < / p >
