A wireless power transfer system has a coil assembly including a ferrite pad and a pair of spaced apart inductive coils on the ferrite pad, and a switching network that, in response to an indication of a corresponding inductive coil assembly configuration, controls a direction of current flow through each of the coils to selectively operate the coils in a two-pole mode or a three-pole mode.
