Principle of mobile phone wireless charging

The mobile phone can be said to be a device that everyone can’t leave their hands. I used to ask myself if I brought my key and wallet when I went out, but now when I go out, the things I ask about become mobile phones and keys, because they are downloaded from the mobile phone. Some payment software can perfectly replace wallets. However, the standby capacity of mobile phones is also limited. If you want to use it for a long time, you must carry a mobile power supply and data cable with you, which increases our burden. Therefore, under the demand of the public, the emergence of wireless charging It became inevitable. So, in our daily life, can we make a wireless charger by ourselves? What principles do we need to know to make a wireless charger?

Principle of mobile phone wireless charging


The principle of making a wireless mobile phone charger is very simple. In fact, it is to separate the primary and secondary parts of some common transformers in life to achieve the purpose of wireless charging. Moreover, the time required to fully charge the wireless charging tool is short, which means that the average work efficiency is high. Even if you discard the core when making a wireless charger, you can use the coil directly to achieve the purpose of energy transfer.

Shenzhen Fandou Technology Co., Ltd. Engineering Department teaches you how to make wireless chargers


First, set the circuit frequency of the most common 555 time base on the market to 1.8KM and put it aside for later use; then use 0.8 enameled wire to wrap around the cylinder. Generally speaking, the diameter of the cylinder is mostly 5 mm, so Use enameled wire to wind about 11 turns on it. Repeat this work to make two coils for use. The power supply must be a 19V switchable power supply during preparation, remember! The power supply used here must be switchable!

After that, you need to make the circuit for charging. If you are not confident about this work, you can use the old or the universal charger that has already been decided to be eliminated. Connect a coil made before to the prepared charging circuit, and then connect the third pin, the 555 output pin, to the high-frequency power tube, and then connect the coil and the output tube. Gradually bring the two connected coils closer together, and the distance is about one centimeter. Finally, we only need to turn on the power and press the switch to start wireless charging!


 


Of course, if you feel that you can’t do it yourself, you can buy the wireless charger equipment from the Engineering Department of Shenzhen Fandou Technology Co., Ltd., which can also achieve the purpose of wireless charging.
