Electromagnetic induction: The fundamental principle is the use of electromagnetic inductionSimilar to a transformer, a certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end creates eddy currents in the magnetic field, while the receiving coil at the mobile device endIt senses this vortex. In this way, power is transferred from the charger to the mobile device.
