COIL TOPOLOGIES FOR INDUCTIVE POWER TRANSFER
First Claim
1. A magnetic flux device configured to transmit or receive magnetic flux to or from a space beyond the magnetic flux device, the magnetic flux device comprising:
- at least a first electrically conductive coil and a second electrically conductive coil, the first coil having a first layer and second layer, the second coil having a third layer and fourth layer, the first layer substantially coplanar with the third layer; and
a magnetically permeable magnetically permeable material having a substantially planar first surface, a second surface adjoined to the first surface at a first edge, and a third surface adjoined to the first surface at a second edge, the first coil extending over the first edge and intersecting a plane of the first surface, the second coil extending over the second edge and intersecting the plane of the first surface.

Abstract
This disclosure provides systems, methods and apparatus including a magnetic flux device configured to transmit or receive magnetic flux to or from a space beyond the magnetic flux device. In certain configurations, the magnetic flux device can include a first coil with a first layer and second layer, a second coil with a third layer and fourth layer, and a magnetically permeable material with the first coil extending over a first edge of the magnetically permeable material and the second coil extending over a second edge of the magnetically permeable material. In certain other configurations, the magnetic flux device can include a first conductive structure including a first coil and a second coil enclosing a first area and a second area, respectively. The magnetic flux device can further include a second conductive structure with at least a first planar portion of the first conductive structure being substantially coplanar with a second planar portion of the second conductive structure.
