用于减小针对无线电感电力传送的极化线圈系统的发射的系统和方法

Abstract

本公开包括用于减小针对无线电感电力传送的极化线圈系统的发射的系统、方法和装置。一方面,提供磁通量盘,其至少包括第一导电线圈以及与第一线圈基本上共面的第二导电线圈。盘包括具有基本上平面的表面的可导磁材料。第一线圈和第二线圈基本上平行于基本上平面的表面。材料的区域延伸越过第一线圈的区域并且越过第二线圈的区域。线圈的区域可以基本上环绕第一线圈的区域和第二线圈的区域。
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 pad 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 pad 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.
