An apparatus for wirelessly transferring power to a receive coupler is provided. The apparatus comprises a first coupler connected to a second coupler. The apparatus further comprises a third coupler overlapping the first and second couplers. The apparatus further comprises a controller configured to receive power from at least one power supply, provide a first current to the first coupler and the second coupler in a first charging mode, and provide the first current to the first coupler and the second coupler and provide a second current to the third coupler in a second charging mode. A magnetic flux generated by the first current passing through a first portion is constructively additive with a magnetic flux generated by the first current passing through a second portion.
