What is the wireless charging coil receiving ring

Simply put, the wireless charging receiver coil is to receive the current emitted by the wireless charging transmitter coil. When the transmitter coil emits current, the receiver coil receives the emitted current to the current storage terminal. The characteristics of these wireless charging receiver coils that you may not know:

The wireless charging coil uses the wireless transmitting coil to transmit electric energy in the electric and magnetic fields between the charger and the device, and the receiving coil and capacitor form resonance between the charger and the device. The loss of wireless charging technology is lower than that of wired charging technology.

The conversion rate of wireless charging is several percentage points higher than that of wired charging. High conversion is also a key factor for wireless chargers to be applied globally.

The core chip is one of the difficulties in the application of wireless charging technology in products. The precise radiation range control, the size of the magnetic field frequency, and other controls are all realized by the chip.

In addition, the magnetic field used by the wireless charging coil itself is harmless to the human body. However, wireless charging technology is a new type of charging technology after all. In the case of wireless chargers, many people are worried that wireless charging technology will be the same as Wi-Fi and mobile phone antenna poles just appeared. In fact, the technology itself is harmless.

From the perspective of user needs, the performance of the wireless charging transmitting coil and the wireless charging receiving coil are the same, and the two need to exist at the same time to form a wireless charging mode.

With the advancement of electronic technology, it is believed that in the next few years or more than ten years, mobile phone wireless charging will prevail in every household, and the industry of wireless charging coils will also usher in an invisible explosive point.

The impact of wireless charging coils on daily life

With the latest wireless charging functions updated by Samsung, Apple and other hot-selling mobile phones, more and more businesses have begun to pay attention to and invest in the development of wireless charging technology.

The emergence of mobile phone wireless charging technology has indeed brought a lot of convenience to our lives. The first thing we learned about mobile phone wireless charging is to add a base with a wireless charging transmitter coil to a wireless charging transmitter coil. Wireless charging can only be carried out when the mobile phone is put together, but this is not fundamentally wireless charging. On the contrary, it is still the same as wired charging. Later, with the new upgrade of technology, mobile phone wireless charging can be directly charged with Built-in wireless charging receiving coils, such as Samsung mobile phones, can achieve wireless charging by approaching a power bank with a built-in wireless charging transmitter coil. This fundamentally achieves the realization of wireless charging, so does the wireless charging coil have an impact in our lives? ?

Since mobile phone wireless charging is a relatively novel charging method in electronic technology, its principle is actually very simple, that is, the ordinary transformer is mainly divided into a wireless transmitting coil and a wireless receiving coil to achieve the purpose of wireless charging. Of course, the working frequency of wireless charging is relatively high, and you can even abandon the core and directly wirelessly charge between the coils to achieve the effect of energy transfer.

1. In theory, wireless charging technology is safe and harmless to the human body. The resonance principle used in wireless charging is magnetic field resonance, which only transmits between wireless charging coils that resonate at the same frequency, while other devices cannot accept the band. In addition, wireless The magnetic field used by the charging technology itself is harmless to the human body. But wireless charging technology is a new type of charging technology after all. With Maiyuan Technology’s wireless chargers, many people are worried that wireless charging technology will be the same as Wi-Fi and mobile phone antenna poles. In fact, the technology itself is harmless. .

　　2. The wireless charging technology uses magnetic resonance to transmit electric energy in the electric and magnetic fields between the charger and the device, and the coil and capacitor form resonance between the charger and the device.

　　3. This system can be widely used in the future, such as charging areas for electric vehicles and power transmission for computer chips. The charging time required for the charging system developed using this technology is only one-150th of the current one

　　4. The conversion rate has always been a concern for many people. Research by MIT has shown that the loss of wireless charging technology is lower than that of wired charging technology. The conversion rate of wireless charging is several percentage points higher than that of wired charging. High conversion is also a key factor for wireless chargers to be applied globally. However, wireless charging technology is also limited by distance. Future development will inevitably need to solve the problem of precise positioning of the waveband and magnetic field for long-distance transmission.

　　 5. The core chip is one of the difficulties in the application of wireless charging technology in products. The precise radiation range control, the size of the magnetic field frequency, and other controls are all realized by the chip.
