Abstract
A power receiver device of a non-contact power feeding device includes a plurality of resonance circuits that receive power from a power transmitter device, a voltage detection circuit that detects an output voltage from the plurality of resonance circuits, and a control circuit. Receiver coils of the plurality of resonance circuits are arranged so as to be electromagnetically coupled to each other. At least one of resonance circuits includes a variable capacitance circuit that is connected to the receiver coil of the resonance circuit and is regulatable in capacitance. The control circuit regulates the capacitance of the variable capacitance circuit in accordance with the output voltage.
