Abstract
The present invention relates to a wireless power transmitting device and method which are configured to: transmit a first state confirmation signal through a first transmitting method; transmit power through the first transmitting method when a first state response signal corresponding to the first state confirmation signal is received; and transmit a second state confirmation signal through a second transmitting method when the first state response signal is not received. According to the present invention, the wireless power transmitting device alternatingly uses the first transmitting method and the second transmitting method, and the existence of a wireless power receiving device and a receiving method thereof can be detected.

1-14. (canceled)
A wireless power transmitting method comprising:
- transmitting a state confirmation signal from one of a first transmitting coil which transmits power through a first transmitting method and a second transmitting coil which transmits power through a second transmitting method to a wireless power receiving device;
- receiving a response signal corresponding to the transmitted confirmation signal;
- transmitting the power to the wireless power receiving device through one of the first transmitting method and the second transmitting method based on the received response signal.
A wireless power transmitting device comprising:
- a first coil configured to transmit power through a first transmitting method;
- a second coil configured to transmit the power through a second transmitting method;
- and
- a controller configured to transmit a state confirmation signal from one of the first coil and the second coil to a wireless power receiving device, receive a response signal corresponding to the transmitted state confirmation signal, and transmit power to the wireless power receiving device through one of the first transmitting method and the second transmitting method based on the received response signal.
