1. A method of controlling a wireless power receiver, the method comprising:
receiving, by a power receiver, power from a wireless power transmitter;
receiving, from the wireless power transmitter, a time set value that is set for checking cross connection [ , wherein the time set value is set by the wireless power transmitter] ;
in response to receiving the time set value, generating a power variation in the wireless power receiver by converting a load status from a first load status to a second load status; and
maintaining the second load status for a time corresponding to the received time set value.
