Abstract
A misalignment tolerant foreign object detection approach is proposed for use with wireless charger systems where sensor coils or portions thereof are mirrored about one or more axes of radial symmetry. A first variant is proposed adapted for x-axis misalignment tolerance, and a second variant is proposed for simultaneous x and y axis misalignment tolerance. Further variants are proposed with additional rotational misalignment tolerance. Detection of the foreign object despite misalignment in receiver and transmitter coils is an important safety and efficiency consideration.
