Abstract
Systems, methods and apparatuses for reducing the height of bipolar transmitters and/or receivers in electric vehicle charging and/or power transfer are described herein. One implementation may include an apparatus for wireless power transfer. The apparatus comprises a ferromagnetic layer comprising at least one portion having a reduced thickness. The apparatus further comprises a first coil having at least one portion countersunk into the at least one portion of the ferromagnetic layer having the reduced thickness. The apparatus further comprises a second coil overlapping the at least one countersunk portion of the first coil. The at least one portion having the reduced thickness comprises a recess in the ferromagnetic layer. The ferromagnetic layer comprises a first plurality of ferromagnetic tiles having a first thickness and the at least one portion having the reduced thickness comprises a second plurality of ferromagnetic tiles having the reduced thickness.
