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, and a power receiver circuit that outputs, to a load circuit, the power received from the power transmitter device by the plurality of resonance circuits. Each of the plurality of resonance circuits includes a receiver coil that receives power from a transmitter coil of the power transmitter device, and a resonance capacitor that resonates, together with the receiver coil, with AC power supplied to the transmitter coil of the power transmitter device. The receiver coils of the plurality of resonance circuits are arranged so as to be electromagnetically coupled to each other.
