WIRELESS POWER TRANSFER APPARATUS AND POWER SUPPLIES INCLUDING OVERLAPPING MAGNETIC CORES

摘要

A primary coil can be inside the recess, where the primary coil is wound around the center of the recess. A secondary magnetic core can include a protruding center portion that is configured for insertion into the center of the recess so that the protruding center portion overlaps the primary magnetic core side wall and is configured to provide separation between the primary magnetic core and the secondary magnetic core. A secondary coil can be wound around the protruding center portion of the secondary magnetic core.
