Abstract

A respective first signal is applied to a first terminal of each of one or more litz coils and each of one or more printed circuit board (PCB) coils. A respective second signal is received from a second terminal associated with each of the one or more litz coils and the one or more PCB coils. The respective second signal is based on the respective first signal applied to the first terminal of each of one or more litz coils and each of one or more PCB coils. A coil is selected from the one or more litz coils and the one or more PCB coils where the selected coil is based on the respective second signal from the second terminal associated with each of the one or more litz coils and the one or more PCB coils to wirelessly transfer the power to an electronic device.
