Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will produce a magnetic field, its wireless charging principle his unenergized coil (mobile phone end of the electric coil) close to the magnetic field will produce current, charging the mobile phone. As shown below.
2, wireless chargingCalled inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it does not need 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, it is the first generation of mobile phone wireless charging, the technology is mature, but can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging.
4, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the connection to the terminal device that needs to be charged without the traditional charging power cordThe charger on the charger, using the wireless charging principle The latest wireless charging technology, through the use of the magnetic field generated between the coils, the magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
5, 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 mostFor common, Qi labels are often used in the packaging of many mobile phones and wireless chargers.
6, electromagnetic induction This is the most common wireless charger working mode, using 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 transmission wireless charging principle ; The implementation of this wireless charger has been promoted by the Wireless Charging Alliance.
After wireless charging, you can better protect the interface of the phone, and you can also have power anytime and anywhere. They will not worry about what to do when they go out without electricity, just put it on the charging site. Some people often drop their phones when using wired chargers, but this will never happen with wireless. This kind ofWireless chargers are designed to meet the needs of more young people.
Electromagnetic induction wireless charging, is the use of the power supply side (wireless charging board) and the induction magnet on the receiving side (mobile phone) generated between the induction flux, the magnetic force into electricity and then transmission. The advantage of this charging method is that the circuit structure required by the device is relatively simple, the charging device can be miniaturized, and the cost is cheap, and the charging efficiency will be relatively higher.
The first is field-coupled charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. As they approachWhen, the coupling phenomenon will occur to achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
Wireless charging of mobile phones is very convenient and not without practical significance. It is not unnecessary, wireless charging is still very convenient, such as urgent things he can let you keep full charge, when you are in front of the computer office, after using the mobile phone on the wireless charging board, you can keep full charge for it.
WirelessCharging helps improve security Using wireless charging technology means users don't have to connect their iPhone to an unknown cable, which is where all the malicious stuff hides. Placing an iPhone on a charging pad should be safe -- unless a hacker develops a malicious device that uses wireless charging, which so far doesn't exist.
1, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and mobile phone equipmentThe two pieces of "magnetic equipment" sense each other and form an electric 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 Qi labels are often used in the packaging of many mobile phones and wireless chargers.
2, 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. 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. Go byAfter the power management module output direct current through 2M active crystal inverter converted into high frequency alternating current supply primary winding.
