Abstract
An apparatus for determining a relative position of a wireless power transmitter from a wireless power receiver is provided. The apparatus comprises a plurality of sense coils, each configured to generate a respective voltage signal under influence of a first alternating magnetic field oscillating at two frequencies and a second alternating magnetic field oscillating at at least one frequency. The apparatus further comprises a processor configured to determine the relative position of the wireless power transmitter from the wireless power receiver based on the respective voltage signal from each of the plurality of sense coils.
