    Abstract: One innovation includes a system for reducing magnetic flux of a wireless charging field in a wireless power charging system. The system comprises a wireless power transmitter configured to generate the wireless charging field, the field comprising the magnetic flux and a collector comprising a ferromagnetic material and configured to reduce the magnetic flux. The collector is positioned between a first distance and a second distance at a third distance from the transmitter. The collector is configured to reduce the magnetic flux at a first level at the first distance, at a second level at the second distance, and at a third level at the third distance, the third level greater than each of the first and second levels.

    Abstract: Techniques for determining power electronics feasibility in a wireless power transfer system with a transmitting element and a receiving element are provided. An example apparatus includes a processor configured to receive FEM simulation results for offset positions between the transmitting element and the receiving element, calculate a total real input current variation for the offset positions based on the FEM simulation results, calculate an indication of a difference between an ideal transmitting element current value and a real transmitting element current value for each of the offset positions based on the FEM simulation results, determine a maximum difference value based on the indication of the difference for each of the offset positions, and determine the power electronics feasibility based on the total real input current variation as compared to a total real input current variation threshold value, and the maximum difference value as compared to a maximum difference threshold value.

    Abstract: This disclosure provides systems, methods and apparatus for avoiding magnetic power loss while providing alternating current through a ferromagnetic material. In one aspect, the ferromagnetic material includes at least one orifice. At least one electrical conduit extends through the at least one orifice from a first region on a first side of the ferromagnetic material to a second region on a second side of the ferromagnetic material, the second side opposite to the first side. The at least one electrical conduit is configured to have at least one alternating current flowing along the at least one electrical conduit between the first region and the second region. The ferromagnetic material and the at least one electrical conduit are configured to reduce power loss caused by a circumferential magnetic flux generated within the ferromagnetic material by the at least one alternating current.
