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. The input terminal will be AC mains when the system is workingThe full bridge rectifier circuit is converted into direct current, or the 24V direct current terminal is used to supply power to the system. 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.
If you usevivo mobile phone, 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.
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.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wavesTransmission and other methods, mobile phone wireless charging 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.
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. Since the energy is transmitted between the charger and the electrical device in an inductive coupling, no wires are connected between the two, so the charger and the electricity are usedDevices can be made without exposing conductive contacts. Wireless charging mainly uses the principle of electromagnetic induction, magnetic resonance and radio wave technology.

2, wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, no needLike a traditional wired charger, a transmission cable is needed to transmit electricity to the device, but the device that needs to be charged can be charged by touching the wireless charging base.
3, wireless charging system mainly uses the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. 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.
4, the principle of radio waves is to turn the environmental electromagnetic waveThe primary windings are converted to high frequency alternating current supply.
