Title: METHOD AND APPARATUS FOR ADAPTING WIRELESS POWER TRANSFER BETWEEN WIRELESS POWER PROTOCOLS
Abstract:
A wireless power transfer adapter is provided. The wireless power transfer adapter comprises a receive coil configured to receive wireless power from a wireless power transmitter at a first frequency associated with a first wireless power protocol of a plurality of wireless power protocols. The wireless power transfer adapter comprises a rectifier circuit configured to convert the wireless power received by the receive coil from the first frequency to a second frequency associated with a second wireless power protocol of the plurality of wireless power protocols that is different from the first protocol. The wireless power transfer adapter comprises a transmit coil configured to transmit at least some of the wireless power to a wireless power receiver at the second frequency and according to the second wireless power protocol.
