Multi-mode wireless power receiving device and method
First Claim
1. A multi-mode wireless power receiving device comprising:
- an antenna module including an outer loop and an inner loop;
a mode control unit configured to control an operating mode of the antenna module;
a switch connecting the outer loop and the inner loop and operated by the mode control unit;
an outer loop module configured to support a magnetic resonance method and near field communication (NFC) communication by using the outer loop, according to an operation of the switch; and
an inner loop module configured to support a magnetic induction method by using the outer loop and the inner loop simultaneously according to the operation of the switch and to transmit power.

12. A multi-mode wireless power receiving method, the method comprising:
-
receiving at least one of wireless power and a communication signal, which have the same operating frequency, from a wireless power transmitting device; controlling an operating mode of an antenna module by manipulating, at a mode control unit, a switch; supporting transmission of the wireless power and NFC communication of a magnetic resonance method by using an outer loop of the antenna module, if the switch is turned off; and transmitting the wireless power to a wireless power receiving device by connecting the outer loop and an inner loop such that PMA and WPC of a magnetic induction method are supported, if the switch is turned on. - View Dependent Claims (13, 14, 15, 16)
