Abstract:
This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect an apparatus for wirelessly transferring power from a charging power source to a device is provided. The apparatus includes a first strand wound in one or more turns and operationally coupled to the charging power source and a second strand wound together with the first strand in one or more turns and operationally coupled to the charging power source. The apparatus further includes an inductor circuit connected to the first strand and disconnected from the second strand. The inductor circuit is further configured to reduce a current difference between a first current flowing through the first strand and a second current flowing through the second strand.
