Wireless power transmitter, wireless power receiver, and methods of controlling the same
First Claim
1. A method of detecting a rogue device other than a wireless power receiver in a wireless power transmitter, the method comprising:
- receiving power consumption information about the wireless power receiver from the wireless power receiver, wherein the power consumption information includes information about at least one of a power dissipated in a reception resonator of the wireless power receiver, a power loss caused by induction of the wireless power receiver, and applied to a rectifier of the wireless power receiver;
calculating a power loss based on the received power consumption information about the wireless power receiver; and
if the power loss exceeds a threshold, shutting down power transmission to the wireless power receiver.

Abstract
A wireless power transmitter, a wireless power receiver, and methods of controlling the same are provided. A method of detecting a rogue device other than a wireless power receiver in the wireless power transmitter includes receiving power consumption information about the wireless power receiver from the wireless power receiver, calculating a power loss based on the received power consumption information about the wireless power receiver, determining whether the power loss exceeds a threshold, and controlling transmission power of the wireless power transmitter, determining that a rogue device exists on the wireless power transmitter, if the power loss exceeds the threshold.

15. A method of controlling a wireless power transmitter that transmits a charging power to a wireless power receiver, the method comprising:
-
detecting existence of the wireless power receiver by applying a search power to the wireless power receiver, the search power being used to detect the existence of the wireless power receiver; transmitting a driving power to the wireless power receiver to drive the wireless power receiver; determining whether to join the wireless power receiver in a wireless power network, and joining the wireless power receiver in the wireless power network based on a result of the determining; transmitting a charging power to the wireless power receiver; and determining whether there is present a rogue device other than the wireless power receiver. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
