摘要： A receiver construction and/or a transmitter assembly is provided for transfer of wireless power. The receiver and/or transmitter assemblies may include a respective receiver or transmitter coil assembly, a backing, and a core provided between the backing and the respective receiver or transmitter coil assembly. The receiver coil assembly and/or the transmitter coil assembly may include one or more coils provided in an epoxy operable to facilitate thermal transfer from the one or more coils to at least one of the core and the backing. A thermally conductive element may be provided between the backing and the core.

摘要： A wireless power supply power supply including first tuning circuitry coupled directly to a transmitter, the first tuning circuitry including an LCC configuration. The wireless power supply may include second tuning circuitry coupled directly to switching circuitry (e.g., an inverter) of the power supply, where the second tuning circuitry may be operable to direct power from the switching circuitry to the first tuning circuitry for supply to the transmitter, and where the second tuning circuitry includes a reactance operable to establish inductive operation of the switching circuitry at the switching frequency of the switching circuitry.

摘要： A shield construction for transfer of wireless power is provided. The shield construction may be a magnetic shield having a plurality of layers and provided for a wireless transmitter or a wireless receiver, or both. The magnetic shield may include a first layer and a second layer, where the first layer may be nearer to a core than the second layer, and where the second layer may include a second layer area that is larger than a first layer area of the first layer. The wireless transmitter and the wireless receiver may be configured to multi-phase wireless power transfer.
