Wireless charger schematic diagram
The wireless charging system mainly uses the principle of electromagnetic induction to achieve transfer through coupling through coils. When the system is working, the input terminal will be powered by direct current. Coupling through two inductors, the current output by the secondary coil is converted into direct current by the receiving conversion circuit to power the LED lamp.
A changing magnetic field will produce a changing electric field, and a changing electric field will produce a changing magnetic field, the size of which is related to their rate of change.
The rate of change of a sine function is another sine function, so electromagnetic waves can spread out, and the induced voltage The generation of is related to the change of magnetic flux, so the changing magnetic field inside the coil generates an induced voltage, thereby completing the power extraction process.
