METHODS FOR FORMING SHIELD MATERIALS ONTO INDUCTIVE COILS |
| 摘要 |
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 may be shielded with a contoured shield made from a ferromagnetic material. The contoured shield may contour to several surfaces of the transmit coil so as to define a single plane through which flux may be directed to a receive coil. |
