SYSTEM AND METHOD FOR REDUCING EMISSIONS FOR POLARIZED COIL SYSTEMS FOR WIRELESS INDUCTIVE POWER TRANSFER

摘要

This disclosure includes systems, methods and apparatus for reducing emissions for polarized coil systems for wireless inductive power transfer. In one aspect, a magnetic flux device is provided which includes at least a first electrically conductive coil and a second electrically conductive coil that is substantially coplanar with the first coil. The device includes a magnetically permeable material having a substantially planar surface. The first coil and the second coil are substantially parallel to the substantially planar surface. The area of the material extends beyond the area of the first coil and beyond the area of the second coil. The area of the coil can substantially surround the area of the first coil and the area of the second coil.
