Beschreibung
Zusammenfassung:	A wireless power receiver includes: a power-receiving antenna configured to receive power wirelessly from a transmitter; power-processing circuitry that is coupled to the power-receiving antenna to receive power from the power-receiving antenna and that is configured to process the power received from the power-receiving antenna; and a controller communicatively coupled to the power-processing circuitry and configured to: determine a value of a dynamic parameter indicative of at least one of content of the power-processing circuitry, operation of the power-processing circuitry, or a relationship between the receiver and the transmitter; and determine an estimated impedance using the value of the dynamic parameter, the estimated impedance being an estimate of at least a portion of reflected impedance presented to the transmitter by the receiver.
