Methods for forming shield materials onto inductive coils

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 can contour to several surfaces of t...

Zusammenfassung: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 can contour to several surfaces of the transmit coil so as to define a single plane through which flux is directed to the receive coil.
