The principle of wireless charging technology is electromagnetic induction, magnetic field resonance, radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certainElectric current, which transfers energy from the transmitting end to the receiving end.
Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
Wireless charging principle: wireless charging mainly uses electromagnetic induction, the charger and the electrical device to transmit energy by magnetic field, and the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. Wireless chargingElectrical technology comes from radio energy transmission technology, which can be divided into two ways of low-power wireless charging and high-power wireless charging.
If the vivo mobile phone is used, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
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 as the systemUnified 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.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
