Abstract

An apparatus and method of using near field communication (NFC) and wireless power transmission (WPT) are provided. A power receiving apparatus includes a resonator configured to receive a power and to output the power. The power receiving apparatus further includes a near field communication (NFC) receiver configured to perform wireless communication using the power output by the resonator. The power receiving apparatus further includes a wireless power transmission (WPT) receiver configured to supply a voltage using the power output by the resonator. The power receiving apparatus further includes a connecting unit configured to selectively connect the resonator to either the NFC receiver or the WPT receiver. The power receiving apparatus further includes a mode selector configured to control the connecting unit to selectively connect the resonator to either the NFC receiver or the WPT receiver based on the power output by the resonator.

Claims

1. A power receiving apparatus comprising:

a near field communication (NFC) coil configured to receive a signal;

an NFC receiver configured to perform wireless communication using the signal;

a wireless power transmission (WPT) resonator configured to receive a power; and

an WPT receiver configured to supply a voltage using the power received by the WPT resonator,

wherein a operating frequency of the NFC coil is different from a operating frequency of the WPT resonator.

2. The power receiving apparatus of claim 1, wherein the power receiving apparatus is configured to operate on the voltage.

3. The power receiving apparatus of claim 1, wherein the NFC coil is disposed within the WPT resonator.

4. A method of operating a power receiving apparatus, comprising:

using a near field communication (NFC) receiver to perform wireless communication using a signal received by an NFC coil; and

using a wireless power transmission (WPT) receiver to supply a voltage using a power received by a WPT resonator,

wherein a operating frequency of the NFC coil is different from a operating frequency of the WPT resonator.

5. The method of claim 4, wherein the NFC coil is disposed within the WPT resonator.
