Abstract: One aspect of the disclosure provides an apparatus for conveying wireless power. The apparatus comprises a circuit board disposed along one or more planar coils and a plurality of feeds. The circuit board is divided into a first area separate from a second area. The first area has a plurality of first voltage components and the second area has a plurality of second voltage components. The first voltage components operates at a lower voltage than the second voltage components. The plurality of feeds are coupled to the one or more planar coils and the circuit board. The plurality of feeds pass through the circuit board within the second area along a side of the circuit board and couple to one or more of the second voltage components.

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: Systems, methods, and apparatus are disclosed for wirelessly charging an electric vehicle. In one aspect, a method for transferring power via a magnetic field in a wireless power transfer system is provided. The method includes outputting an alternating electric current to a wireless power transmitter, generating, at the wireless power transmitter, the magnetic field in response to being driven with the alternating electrical current, receiving a value indicative of an electrical characteristic of the wireless power transmitter, and adjusting an operating characteristic of the wireless power transmitter to trigger a change in an electrical current in the receiver, the amount of adjustment selected to cause adjustment of an amount of reactive power in the wireless power transfer system based on changes in the receiver that automatically occur to maintain the output power substantially constant in response to the change in the electrical current in the receiver.

Abstract: Systems, methods and apparatuses implementing hybrid symmetric and asymmetric control for soft switching in wireless power transfer applications are provided. An apparatus for wirelessly transferring charging power is provided. The apparatus comprises a wireless power coupler. The apparatus comprises driver circuit. The apparatus comprises a control unit configured to instruct a driver circuit to drive the wireless power coupler with a first voltage waveform when transferring wireless charging power less than a first amount. The first voltage waveform includes a positive portion having a first duration and a negative portion having the first. The control unit is further configured to selectively instruct the driver circuit to drive the wireless power coupler with a second voltage waveform when transferring wireless charging power greater than the first amount, the second voltage waveform including a positive portion having a second duration and a negative portion having a third duration that is not equal to the second duration.
