Abstract:
Methods of and systems for directing flux from a transmit coil to a receive coil within an inductive power transfer system are disclosed. For example, a transmit coil can be shielded with a contoured shield made from a ferromagnetic material. The contoured shield contours to several surfaces of the transmit coil so as to define a single plane through which magnetic flux is directed to a receive coil.
