In order to enable a Power Transmitter to monitor the power loss across the interface as one of the possible methods to limit the temperature rise of Foreign Objects, the BQ51013C reports its Received Power to the Power Transmitter. The Received Power equals the power that is available from the output of the Power Receiver plus any power that is lost in producing that output power (the power loss in the Secondary Coil and series resonant capacitor, the power loss in the Shielding of the Power Receiver, the power loss in the rectifier). This means the BQ51013C will send received power information with known accuracy to the transmitter.
To receive WPC Certification the Device Under Test (DUT) is tested on a Reference Transmitter whose transmitted power is calibrated, the receiver must send a received power such that:
This 375-mW bias ensures that system will remain interoperable.
WPC Transmitter is tested to see if it can detect reference Foreign Objects with a Reference receiver.
