Abstract

One aspect of the disclosure provides an apparatus for conveying wireless power. The apparatus comprises a circuit board disposed along one or more planar coils and a plurality of feeds. The circuit board is divided into a first area separate from a second area. The first area has a plurality of first voltage components and the second area has a plurality of second voltage components. The first voltage components operates at a lower voltage than the second voltage components. The plurality of feeds are coupled to the one or more planar coils and the circuit board. The plurality of feeds pass through the circuit board within the second area along a side of the circuit board and couple to one or more of the second voltage components.
