Wireless power transmitter for excluding cross-connected wireless power receiver and method for controlling the same

摘要

A method and apparatus for excluding a cross-connected wireless power receiver in a wireless power transmitter is provided. The method includes determining transmission power while the wireless power transmitter is connected to the wireless power receiver; transferring the determined transmission power to the wireless power receiver; receiving a report indicating a power-receiving state from the wireless power receiver; determining whether the power-receiving state indicated by the report is within a valid range corresponding to the transmission power; and terminating the connection to the wireless power receiver if the power-receiving state is outside of the valid range.

1. A method for controlling a wireless power transmitter configured to transmit power to a wireless power receiver, the method comprising:
applying a detection power for detecting a change in load of the wireless power transmitter caused by placement of the wireless power receiver; detecting the change in load of the wireless power transmitter at a first time point; receiving a first signal from the wireless power receiver at a second time point; and determining whether to transmit a second signal to the wireless power receiver based on a difference between the first time point and the second time point.
