Today to share the industry wide wireless charging knowledge, which will also explain how to wireless charging this project, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging refers to the charger on 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, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. How to use: Connect the USB cable and plug it into the socket.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Wireless charging, 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.

1, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
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 then turnedInstead, current is fed to the smart 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, wireless charging is also known as inductive charging, non-contact inductive charging, from the wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own transportFor use.
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.
5, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the need to connect to the need to charge without the traditional charging power cordThe charger on the terminal device adopts 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 the bridge connecting the charging base station and the device.
Wireless charging is not a castle in the air, but through a special way of power supply. It cleverly uses the propagation characteristics of electromagnetic waves, without the need for physical power lines, to convert the energy of electromagnetic waves into electricity, and then provide lasting power support for our electronic devices. Each waveform is like the heartbeat of a wireless charger, recording the subtle process of energy transmission and conversion.
Small whale Cloud wireless charging device uses low-frequency magnetic resonance technology, the maximum effective charging distance of up to 3CM. Will be wireless when usedThe charging transmitter is placed under the desktop (the desktop cannot be made of metal or magnetic conductive material), and the wireless phone can be charged when it is placed on the desktop sticker.
