POWER RECEIVING DEVICE AND POWER TRANSFER SYSTEM
First Claim
1. A power receiving device capable of receiving a carrier wave transmitted from a power transmitting device without contact and obtaining electric power from the received carrier wave, comprising:
- a carrier receiving section at least including a communication antenna having predetermined inductance and not equipped with an intermediate tap, to receive the carrier wave and generate an induced voltage corresponding to the carrier wave;
a processing section to generate a drive voltage based on the induced voltage and perform data processing using the generated drive voltage; and
an impedance converting section to convert impedance between the carrier receiving section and the processing section.
