Magnetically permeable core for use in wireless power transfer systems
First Claim
1. A magnetically permeable core for use in a wireless power transfer system, including a base having first and second portions extending away therefrom, wherein the first portion extends further from the base than the second portion to maintain an effective flux linkage throughout a range of relative displacements of a receiver from a transmitter;
- wherein the base includes at least one opening that allows access from one side of the base through to a space provided between the first portion and second portion, and the at least one opening extends to the edge of the base.

Abstract
A magnetically permeable core for use in wireless power transfer systems. The core includes a base with first and second portions that extend away from the base. The first portion extends further from the base than the second portion in order to maintain an effective flux linkage throughout a range of relative displacement of a receiving core from a transmitting core. Transmitters and/or receivers for use in wireless power transfer systems may include the magnetically permeable core and windings.

16. A transmitter or receiver for use in a wireless power transfer system, including windings and a magnetically permeable core having a base having first and second portions extending away therefrom, wherein the first portion extends further from the base than the second portion to maintain an effective flux linkage throughout a range of relative displacements of a receiving core from a transmitting core and wherein the windings surround the first portion at least partially in a space between the first portion and second portion;
wherein the windings occupy, at least in part, the space surrounding the first portion that extends further than the second portion, and the windings occupy, at least in part, the space that would be occupied by the second portion were the second portion to extend the same distance from the base as the first portion. - View Dependent Claims (17, 18)

19. A transmitter and receiver for use in a wireless power transfer system, wherein both the transmitter and receiver include windings and a magnetically permeable core, and the magnetically permeable core of the transmitter has a base having first and second portions extending away therefrom, wherein the first portion extends further from the base than the second portion such that the first portion of the magnetically permeable core of the transmitter is in closer proximity to the magnetically permeable core of the receiver than the second portion of the transmitter;
wherein the transmitter windings occupy, at least in part, the space provided between the first portion and second portion, the transmitter windings occupy, at least in part, the space surrounding the first portion that extends further than the second portion, and the transmitter windings occupy, at least in part, the space that would be occupied by the second portion were the second portion to extend the same distance from the base as the first portion. - View Dependent Claims (20)
