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.
