Claim 7:
8. A method for regulating an over-voltage condition in a receiving device of a wireless power system, the method comprising:
converting an alternating current voltage received from a transmitting device of the wireless power system to a direct current voltage;
converting the direct current voltage to a first regulated direct current voltage;
determining that the alternating current voltage exceeds a steady-state operating condition comprising determining that a difference between the direct current voltage and the first regulated direct current voltage exceeds a first threshold and, based thereon, converting the direct current voltage to a second regulated direct current voltage;
measuring a voltage value of the direct current voltage across a sense resistor;
calculating a power value received at the receiving device at the sense resistor;
and communicating the power value received to the transmitting device of the wireless power system.
