Alignment coils of wireless charging for electronic device
Abstract:
One embodiment provides an electronic device including: a processor; a power supply module coupled to the processor; a receiving antenna coupled to the power supply module, wherein receiving antenna cooperates with a transmitting antenna of a wireless charger to charge the power supply module wirelessly; an inductor arranged with respect to the receiving antenna, wherein the inductor comprises a first wire and a second wire through which a first induced voltage and a second induced voltage are generated respectively; a comparator for comparing the first and second induced voltages; and wherein the processor determines if the receiving antenna is aligned with respect to the transmitting antenna of the wireless charger based upon the comparison of the first and second induced voltages. Other aspects are described and claimed.
