Principle of wireless charging: Wireless charging system mainly'> What is the principle of wireless charging?
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and 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.
2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the need to charge without connecting 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 magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and the device.
3, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that by encircling the wire into a ring, or even winding it into a coil, the magnetic field generated will be stronger and more concentrated, which is called"Magnetic effect of current ".
