    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.

    Abstract: Systems, methods and apparatuses for wireless power transfer are disclosed. In one aspect, a wireless power transfer apparatus is provided comprising a casing with at least one projecting member projecting from an inner side of the surface of the casing that is subject to external compression forces. An induction coil and other components such as insulating layers and magnetically permeable members are positioned around at least one of the projecting members and maintained in position by the projecting members. The wireless power transfer apparatus is able to withstand large compressive forces, such as those imparted by heavy vehicles and the like passing over the apparatus when positioned on the ground in a wireless power transfer system.
