OVER VOLTAGE PROTECTION DETECTION
First Claim
1. A wireless power transmitter comprising:
- a resonator configured to generate a wireless field for wirelessly transferring power to a wireless power receiver;
an impedance detector configured to measure an impedance of the resonator; and
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.
