Abstract
Certain aspects of the present disclosure relate to methods and apparatus for detecting, by a wireless power transmitter, an over voltage protection at a wireless power receiver. Certain aspects of the present disclosure provide a wireless power transmitter. The wireless power transmitter includes a resonator configured to generate a wireless field for wirelessly transferring power to a wireless power receiver. The wireless power transmitter further includes an impedance detector configured to measure an impedance of the resonator. The wireless power transmitter further includes a controller configured to detect operation of an over voltage protection mode of the wireless power receiver based on a frequency of change in impedance as measured by the impedance detector.
