Claim 10:
11. A method performed by an apparatus of a wireless power transfer system, the method comprising:
receiving, via a secondary coil, an induced power having an AC voltage from a primary coil of a contactless power transfer unit;
converting, by a converting unit, the induced power having the AC voltage to an output power having an output DC voltage;
providing the output power having the output DC voltage to an electric load;
communicating, by a first transceiver, a voltage signal to a second transceiver of the contactless power transfer unit, the voltage signal representative of the output DC voltage across the electric load;
controlling, by a controller electrically coupled to a switching unit coupled to the converting unit, at least one switch to regulate the output DC voltage to a voltage reference value when the output DC voltage is above the voltage reference value and below a threshold value; and
causing, by the controller, the at least one switch to decouple the converting unit and the first transceiver to transmit a signal to the second transceiver of the contactless power transfer unit indicating the decoupling of the electric load when the output DC voltage exceeds the threshold value, wherein causing the at least one switch to decouple the converting unit protects one or more components of the converting unit from over voltage damage.
