A wireless power transfer (WPT) device includes a polyphase coil network comprising a plurality of phases for transfer of high-frequency AC power, each one of the plurality of phases comprising a phase coil, wherein the polyphase coil network is configured to operate in a polyphase configuration to enable transfer of polyphase high-frequency AC power with a mating WPT device operating in a polyphase mode; and operate in a single phase interoperability configuration to enable transfer of single phase high-frequency AC power with a mating WPT device operating in a single phase mode.

Interoperable wireless charging with polyphase coil network

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.

Tuning circuitry for a wireless power system

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.
