Abstract

An overcurrent detection circuit for use in a transmitter of a wireless power transfer system is provided. The transmitter comprises a transmitter element for generating a field to transfer power to a receiver of a wireless power transfer system. The circuit is adapted to shut down a transmitter of a wireless power transfer system in response to a detected short circuit event. An overvoltage protection circuit for use in a receiver of a wireless power transfer system is also provided. The receiver comprises a receiver element for extracting power from a field generated by a transmitter of a wireless power transfer system, and a switching element electrically connected to the receiver element. The overvoltage protection circuit is adapted to electrically ground the switching element based on an overvoltage event.
