Apparatus and method for transmitting wireless power
First Claim
1. A method for controlling a wireless power transmitter, the method comprising:
- outputting a first power for a wireless power receiver;
detecting an error condition while outputting the first power;
based on detecting the error condition, providing an indication with regard to the error condition and periodically outputting a second power for detecting a load variation; and
in response to detecting the load variation, determining that a cause of the error condition is removed.

Abstract
A method and apparatus are provided for determining, by a wireless power transmitter, whether a wireless power receiver is removed from a wireless power network managed by the wireless power transmitter. The method includes transmitting a command signal to report power information of the wireless power receiver at stated periods; determining whether a report signal corresponding to the command signal is received from the wireless power receiver; and determining that the wireless power receiver is removed from the wireless power network, if the report signal is not received after transmitting the command signal a predetermined number of times at the stated periods.
