Abstract
Systems, methods, and apparatuses utilizing a bipolar double D vehicle coupler in wireless power transfer applications are described herein. Some implementations may include an apparatus for wireless power transfer. The apparatus comprises a first coil and a second coil connected in series to form a first circuit. The first coil does not overlap the second coil. The apparatus comprises a third coil and a fourth coil electrically connected in series to form a second circuit. The third coil does not overlap the fourth coil. At least a portion of the first circuit overlaps at least a portion of the second circuit. The first circuit is substantially magnetically decoupled from the second circuit.
