COIL ARRANGEMENTS IN WIRELESS POWER TRANSFER SYSTEMS FOR LOW ELECTROMAGNETIC EMISSIONS

摘要

The present disclosure provides systems, methods, and apparatus for wireless power transmission. In one aspect, the disclosure provides an apparatus for wirelessly transmitting power. The apparatus includes a first conductive structure having a length greater than the width and configured to wirelessly receive power through a magnetic field. The first conductive structure includes two substantially coplanar loops. The first conductive structure has first and second edges that respectively intersect the geometric lines along the length of the first conductive structure. The apparatus further comprises a second conductive structure having a length greater than the width and positioned between the first conductive structure and the magnetic material and configured to receive power wirelessly through the magnetic field. The length of the second conductive structure is substantially equal to the distance along the geometric line between at least the first and second edges of the first conductive structure.
