Abstract

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.
