Abstract
A wireless power receiver includes circuitry configured to receive a wirelessly induced voltage from a wireless power transmitter via a magnetically induced connection with the wireless power transmitter. It is determined that an overvoltage condition exists when the wirelessly induced voltage exceeds a threshold voltage, and the wirelessly induced voltage is reduced in response to determining that the overvoltage condition exists. The circuitry communicates the overvoltage condition to the wireless power transmitter via the magnetically induced connection while over-voltage protection is enabled.
