A system and method for charging at least one target device (29) having a secondary coil (27) positionable in a charging receptacle (25) having a primary coil (23) connected to a source of electrical power, wherein the secondary coil of the target device is out of precise alignment with the primary coil when the target device is positioned in the receptacle. A plurality of steering coils (22-22) are arranged around the primary coil. A control circuit (24) changes the magnetic field phase pattern of the steering coils relative to the phase of magnetic field of the primary coil in a selected sequence until the maximum power transfer between the primary coil and the secondary coil is determined. Charging of the target device is continued with the maximum power transfer steering coil phase pattern. |
