    Abstract: 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.

    Abstract: This disclosure provides systems, methods and apparatus for wireless power transfer and particularly wireless power transfer to remote system such as electric vehicles. In one aspect an apparatus for use with a wireless power transfer transmitter device comprising a first inductive element for generating a magnetic field, is provided. The apparatus comprises a direct current (DC) power source having an adjustable output voltage. The apparatus also comprises an inverter configured to convert the adjustable output voltage of the DC power source to alternating current. The apparatus also comprises at least one controller configured to receive an indication of current in the first inductive element and control the output voltage of the DC power source in response to the indication of current in the first inductive element. The apparatus reduces distortion signals in the alternating current output of the inverter while maintaining current in the inductive element substantially constant.
