1, 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 intelligentTerminal. 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.
2, 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, 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 the connection of the charging base station andBridge of equipment.
3, if the use is vivo 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.
