Wireless power transmitter, wireless power receiver, and methods of controlling the same

摘要

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.

主权项

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.
