Today to share with you the South Bay large coil wireless charging knowledge, which will also explain the wireless coil production process steps, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding. 2, wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, does not need to be like the traditional wired charger need to transmit cables to the device, but willThe bridge rectifier circuit is converted into direct current, or the 24V direct current terminal is used to supply power to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding. 2, wireless charging is 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.
3, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the use of traditional charging powerThe 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 the bridge connecting the charging base station and the device.
4, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and 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 receiving conversionThe circuit changes to direct current to charge the battery.
5, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."
6, there is no strong radiation, no effect on the human body! The main principle is: the way of wireless charging has electromagnetic induction and magneticResonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
Momis wireless charger UD13D Features: ultra-thin body design Praise rate: 95 Momis wireless charger UD13D is a charger that supports 15W wireless charging, and only supports a charging method of wireless charging. The product is designed with disk shape, small and flat, and does not occupy an area. The bottom metal body is resistant to wear and increases the texture and stability of the product. productSupport 15W output, backward compatible with 10W, 5W and other wireless charging modes, and passed the FCC, CE, RoHS certification.
The iPhone 12 supports wireless charging. Apple 12 supports MagSafe wireless charging and Qi wireless charging two charging methods, but does not support wireless reverse charging. The power of MagSafe wireless charging is 15W, and the power of Qi wireless charging is 5W. The Apple 12 also supports wired fast charge, which has a maximum charge of 20W and can be charged to 50% in up to 30 minutes, but requires a power adapter of 20 watts or more.
Apple Wireless charger recommended original style Apple magnetic charger: designed for iPhone 12 and above series, aluminum metal shell highlights quality. Built-in thermostatic system to protect the battery, 15W power is suitable for fast-paced life, is a good choice for closing eyes. Apple MagSafe Dual charger: The simple design is impressive, and the vertical Watch charging module is practical and portable.
Mobile phones use wireless charging,You need to purchase a wireless charging base or wireless charging rear case to use it. Connect the charger to the wireless charging base, and then place the phone or a phone with a wireless charging back case on the wireless charging base. Take off the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to take off the holster and try charging.
Some high-end mobile phones of Huawei can support wireless charging in addition to super wired fast charging, and wireless chargers need to be purchased separately to use wireless charging. How to use Huawei wireless charger? Connect the power supply to the charger (come with the phone or buy it separatelyCharging head) Connect to the power supply. Connect the data cable Connect the charger to the wireless charger using the data cable. Place the phone Place the rechargeable area of the phone in the center of the upper surface of the wireless charger, and the phone shows that it is charging.
Wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
If your Huawei mobile phone supports wireless charging, directly switch the mobile phone to the wireless chargerPlace the screen facing up in the center of the charger or as recommended by the manufacturer to charge.
