The use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coils, the transmitter coil under the action of power to send electromagnetic signals, the receiver coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then 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 direct currentSystem power supply. 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.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technologyIt is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the electrical device, the device uses the received energy to charge the battery, and at the same time for its own operation.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and the packaging of many mobile phones and wireless chargers is introducedIt is often labeled with the Qi label.
Driven by technological innovation, Nanxin Technology constantly breaks through the boundaries of wireless charging technology, and the birth of SC9610&SC8701 marks the arrival of a new era of high-power wireless charging. These two products not only represent the outstanding technical strength of Nanxin Technology, but also promote the entire industry toThe direction of higher power and higher efficiency.
Accompanied by Liu Min and Liang Yingzhen, Director Wang Yong and his delegation first visited the Shanghai office of Nanxin Technology. They reviewed some of the representative solutions and terminal product cases of South Core Technology, and had an in-depth understanding of several representative fast charge solutions and in-depth cooperation terminal projects, including charge pump solution SC8571 series, high-power wireless charging solution SC9610 series, 65W gallium nitride solution and front-loaded vehicle charging solution.Wireless charger Wireless full bridge The working principle is mainly through the magnet induction. When we place the mobile phone in the induction area of the wireless charger wireless full bridge , the magnetic field generated by the magnet will generate induction current inside the mobile phone. This current creates a voltage through the phone's electrical system, which charges the phone. Unlike wired chargers, wireless chargers transmit energy through magnetic fields rather than wires or cables. The key to this working principle is the establishment of magnetic fields.
If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger or the position recommended by the manufacturer after the wireless charger is powered on.
electromagnetic induction. This is the most common wireless charger working mode, it uses the principle of electromagnetic induction, through the primary and secondary coil between the electromagnetic induction to generate current, so as to achieve the energy in the space of the transfer; The implementation of this wireless charger has been promoted by the Wireless Charging Alliance.
Wireless charging technology mainly transmits electrical energy through the principle of electromagnetic induction. During wireless charging, chargeThat is, the current is converted into a magnetic field, and the magnetic field is transmitted through the air and then 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.
3, because the charger and the electrical device are inductively coupled to transmit energy, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. Wireless charging mainly uses electromagnetic induction and magnetic fieldPrinciples of resonance and radio wave technology.
4, the principle of wireless charging is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
First, make sure you have a compatible Apple device and a wireless charger. The Apple Wireless Charger is suitable for Apple devices that support wireless charging, such as iPhone 8 and newer versions, AirPods with charging cases, etc. At the same time, you need an Apple original wireless charger or a third-party wireless charger certified by Apple.The steps to prepare for use are fairly simple.
First, we need to buy a wireless charger. And then he plugs one end into this socket. Plug one end into this wireless charger. In fact, its use is the same as the charger, one end needs to be connected to the power supply, and one end needs to be plugged into the wireless charger. And then we just need to put the phone on this wireless charger.
How to use wireless charging for iphones is as follows: Buy a wireless charger: You need to buy a wireless charger for iphones. You can choose from Apple official or third-party brands of wireless chargers. At the time of purchase, make sure that the charger supports Apple's wireless charging standard. Place the phone and charger: Place the iPhone in the charging area of the wireless charger, making sure that the phone is in good contact with the charger.
Wireless charging setting method of Apple mobile phone: click [battery] in the phone setting menu, click the option of [wireless charging setting], and turn on the switch on the right of [charging silent mode].
