Wireless charging technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally achieve wireless charging. Electromagnetic induction is often used for low-power wireless chargingFor example, the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode.
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.
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, which uses the latest wireless charging technology and is produced between coilsGenerated magnetic fields, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and equipment.
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 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.
Wireless charging, also known as inductive charging, non-contact inductive charging, yesUsing near-field induction, or inductive coupling, energy is transferred from the power supply device (charger) to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
1, the wireless charging system mainly uses 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, and uses the latest wireless charging technology by using the magnetic field generated between the coilsIn order to transfer power, inductive coupling technology will become a bridge connecting charging base stations and equipment.
2, the working principle of the wireless charger is mainly through the magnet induction. When we place the phone in the inductive area of the wireless charger, the magnetic field generated by the magnet will generate an inductive current inside the 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.
3, the use of electromagnetic induction principle for chargingThe principle of the device is similar to that of the transformer, by setting a coil at the transmitting end and the receiving end, the transmitting end coil sends an electromagnetic signal out under the action of power, and the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve the purpose of wireless charging.
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 is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, yesUsing near-field induction, or inductive coupling, energy is transmitted by the power supply device (charger) to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
