Abstract
An apparatus includes an enclosure and a coil assembly in the enclosure. The coil assembly includes a magnetic core and a coil disposed on the magnetic core. The magnetic core is positioned adjacent a wall of the enclosure such that a direction of a main flux path in the magnetic core is through at least one portion of the wall having a magnetic permeability greater than air. Such an arrangement may be used for a wireless power receiver unit configured to be installed in an equipment rack in data center applications.
