Abstract
A wireless power system providing protection from overvoltage conditions. A wireless power receiver has one or more magnets to allow detection of a distance of the wireless power receiver from a wireless power transmitter using a Hall effect sensor. When the detected distance is less than a determined threshold, the wireless power transmitter is instructed to transmit power. The wireless power receiver has one or more transient voltage suppression (TVS) diodes communicatively connected so that when a determined operating voltage of a protected portion of the receiver is exceeded, the TVS diodes provide a low impedance path for transient current to divert the transient current away from the protected portion of the receiver. When the wireless power receiver detects an overvoltage condition, the receiver sends a reset command to the wireless power transmitter.
