摘要：A method and a system for self-regulating wireless power transmitted to awireless power receiver (WPR) are provided. An auto-tuning network is operably coupledwithin the WPR. The auto-tuning network includes an impedance network that
dynamically increases, decreases, or maintains an amount of the received wirelesslytransmitted power by detecting changes in a rectifier load disposed in the WPR and/or ina rectifier output voltage in the WPR. The auto-tuning network self-regulates thewireless power received from a wireless power transmitter (WPT) obviating the need forconventional communication messages. The WPT is hence free from a
modulator/demodulator block and an out-of-band communication block and operatesover a limited operating range to enable a simpler design for passing electromagneticcompliance regulations. The WPR implements a receiver-maximum-power-signaturealgorithm for enabling the WPT to detect unsupported receivers, configure its operatingpoint and range, and terminate power transmission when not needed by the WPR.
