What is a wireless charger? What are the features?

Wireless Charger refers to the charger that is connected to the terminal device that needs to be charged without the traditional charging power cord. It adopts the latest wireless charging technology and transmits electric energy by using the alternating magnetic field generated between the coils. The inductive coupling technology will become the bridge connecting the charging base station and the equipment.

Wireless charger

Features:

1. From a theoretical point of view, wireless charging technology is harmless to human body. The resonance principle used by wireless charging is magnetic resonance, which is only transmitted between coils that resonate at the same frequency, while other devices cannot accept the band. However, wireless charging technology is a new type of charging technology after all. For the wireless charger of maiyuan technology, many people will worry that wireless charging technology will be as harmless as the emergence of wi-fi and mobile phone antenna.

2. Wireless charging technology USES magnetic resonance to transmit electricity in the electric and magnetic fields between the charger and the device, while coils and capacitors form resonance between the charger and the device.

3. This system could be widely used in the future, such as charging areas for electric cars and power transmission for computer chips. A charging system based on this technology would require one-150s of the current charging time.

4. Conversion rates have long been a concern for many people. A study by the Massachusetts institute of technology shows that wireless charging technology has lower loss than wired charging technology. The conversion rate of wireless charging is several percent higher than that of wired charging. High conversion is also a key factor for wireless chargers to be used around the world. However, wireless charging technology is also limited by distance. In the future development, it is necessary to solve the problem of accurate positioning of wave band and magnetic field range in long-distance transmission.

5. Core chip is one of the difficulties in the application of wireless charging technology in products. Precision radiation range control, magnetic field frequency and other control are all realized by the chip.
