WIRELESS POWER SYSTEM AND METHOD WITH IMPROVED ALIGNMENT

摘要

A wireless power system that may align a portable electronic device with an inductive wireless power supply. The induction coils used for transferring power wirelessly may be used as DC electromagnets to align the portable electronic device with the inductive wireless power supply. A DC current may be supplied to the primary coil and to the secondary coil to generate DC electromagnetic fields and attractive force between the primary and secondary coils. This attractive force may be used for alignment.
