Abstract
A wireless power receiver may include a receive coil configured to generate an AC power signal responsive to wireless power transfer from a wireless power transmitter, and control logic configured to detect misalignment of the receive coil and a transmit coil of the wireless power transmitter responsive to a determination of efficiency of wireless power transfer therebetween. A method for operating a wireless power receiver may include detecting misalignment between a receive coil and a transmit coil of a wireless power transmitter responsive to detecting monitoring a value indicative of efficiency of wireless power transfer between the wireless power transmitter and the wireless power receiver, and causing an indication to be provided to a user to assist with correcting the misalignment.
