Wireless Charging Module principle of wireless charging

1.Wireless Charging Module system mainly adopts the principle of electromagnetic induction to realize the energy transfer through energy coupling by coil. The system works by converting AC mains power into DC power through a full-bridge rectifier circuit at the input side, or by directly supplying power to the system with 24V DC power.

2. After the power management module, the output DC power is converted into high frequency AC power through 2M active crystal inverter to supply the primary winding. Coupling energy through 2 inductor coils, the current output from the secondary coil is changed into DC for charging the battery by accepting the conversion circuit.

3. The changing magnetic field will produce the changing electric field, and the changing electric field will produce the changing magnetic field, and their sizes are all related to their rates of change, and the rate of change of the sinusoidal function is another sinusoidal function, so the electromagnetic wave can propagate out, and the generation of the induced voltage is related to the change of magnetic flux, so the changing magnetic field inside the coil produces the induced voltage, thus completing the charging process.
