Principle of wireless charger

2021-05-11 18:20:16

In recent years, many domestic flagship mobile phones have been equipped with the wireless charger function. When it comes to wireless chargers, the wireless charger that my friends think of is like WIFI. As long as our mobile phone is within a certain range, our mobile phone can be given to the mobile phone like a mobile phone Charging, so many of our mobile phones now also support wireless charger, but when charging, we need to put the mobile phone on a charging board, so let's understand what is the principle of the wireless charger on our mobile phone?

Wireless Charger

Since it is a wireless charger, why must the mobile phone be placed in the designated area of the charging board when the mobile phone is charging? Our current wireless charger methods mainly include four types of electromagnetic induction, magnetic field resonance, and electric field coupling. The other is the electric wave method. Among the four methods, electromagnetic induction is more mature and has higher charging efficiency. Furthermore, its circuit structure will be relatively simple, so our mobile phone currently uses this electromagnetic induction type.

The working principle of electromagnetic induction is also very simple. I must have learned in physics class that there are two coils on the charging board and the mobile phone. When the coil of the charging board is connected to the power supply, add AC to the coil below. A constantly changing magnetic field is generated. When we put the phone on the charging board, the coil on the back cover of the phone will sense the change in the magnetic field. The coil on the back cover of the phone induces a current, and then converts the current into The direct current charges the battery of our mobile phone, thus realizing the wireless charger.


But at this stage, its effective charging distance is about 10mm or less, and our mobile phone needs to be placed in the center when charging. If it is not in the center, it will directly affect the efficiency of the wireless charger. Jaskey Limited recently launched several multi-functional wireless chargers, come and buy!
