Wireless charger principle

The wireless charging system mainly adopts the principle of electromagnetic induction, and energy coupling is carried out through the coils.As you can see, the input side of the system is converted into direct current by the complete bridge rectifier circuit, or the direct current system of the 24V direct current is supplied to the system.

The direct current output from the power management module is converted to the primary windings of high frequency alternating current by using the 2M active vibration inverters.By coupling the energy of two inductors, the secondary coil's output is converted into a direct current to charge the battery.

Changing magnetic field produces electric field, the changes of the electric field produces changing magnetic field, its size and they have a relationship, the rate of change and the rate of change of sine function is another sine function, so the electromagnetic wave can spread out, and the generation of induced voltage associated with the change of magnetic flux, so the coil internal changing magnetic field produces induced voltage, thus completing the process of charging.

Wireless charging is a relatively new way of charging, and the idea is simply to separate common transformers from the main ones to achieve wireless ends.Of course, the wireless charge is relatively high and can even be used to achieve energy transfer by ditching the direct coil.
