Abstract:
A method and system for self-regulating wireless power transmitted to a wireless power receiver (WPR) is provided. An auto-tuning network is operably coupled within the WPR. The auto-tuning network comprises an impedance network that dynamically increases, decreases, or maintains amount of the received wirelessly transmitted power by detecting changes in a rectifier load disposed in the WPR and/or in an output voltage of the rectifier in the WPR. The auto-tuning network self-regulates the wireless power received from a wireless power transmitter (WPT) obviating the need for conventional communication messages. The WPT is hence free from a modulator/demodulator block and an out-of-band communication block and can operate over a limited operating range to enable simpler design for passing EMC regulation. Additionally, the WPR implements a receiver-maximum power-signature algorithm for enabling the WPT to detect unsupported receivers, configure its operating point and range, and terminate power transmission when not needed by WPR.
