Classification: CPC H | IPC H

Claim 14:
15. A receiving device of a wireless power system, the receiving device comprising:
a rectifier configured to convert an alternating current voltage to a direct current voltage; a voltage regulator configured to convert the direct current voltage to a first regulated direct current voltage;
a sense resistor configured to measure a voltage value of the direct current voltage; and
a monitoring circuit configured to:
determine that the alternating current voltage exceeds a steady-state operating condition based on a combinational logic of a value of the direct current voltage, the first regulated direct current voltage, and a difference between the direct current voltage and the first regulated direct current voltage and, based thereon, convert the direct current voltage to a second regulated direct current voltage,
calculate a power value received at the receiving device at the sense resistor, and
communicate the power value received to a transmitting device of the wireless power system.
