Abstract
A wireless power relay can include a first wireless power receiver (Rx) configured to receive power from a first wireless power transmitter (Tx) in another device and a second wireless power transmitter (Tx) configured to deliver power to a second wireless power receiver (Rx) in another device. Rxmay be configured to communicate with Txvia a first communication link, and the Txmay be configured to receive communication from Rxvia a second communication link, both employing modulation of the wireless power signal. The relay may further include a power converter with its input coupled to Rxand its output coupled to Txand a constant power controller configured to isolate modulated communication between the communication links. Additionally or alternatively, the relay may include circuitry configured to introduce a jamming signal preventing Txfrom detecting and improperly interpreting signals from the second communications link.
