The Wireless Power Charger Components are compliant with WPC (Wireless Power Consortium) / Qi. The principle is near filed magnetic induction between power transmitter (base station) and power receiver (mobile device) to transfer the contactless power around 5W. The component is composed of coil, shielding and magnet. The coil is used for magnetoelectric transducer. The shielding is used for change the magnetic fields direction and reduce the eddy current when receiver coil attached on mobile device's battery.The magnet is used for alignment aid when mobile device put on base station (WPC design A1).
