Abstract
A method of supplying power in a wireless power receiver can include receiving an AC power via a reception coil in the wireless power receiver; rectifying the AC power to a DC power; transferring the DC power to a load during a charging mode when a voltage of the DC power is equal to or greater than a first threshold voltage corresponding to a target charging power for charging the load; and when the DC power being transferred to the load is less than the target charging power, maintaining the load in the charging mode while the voltage of the DC power is equal to or greater than a second threshold voltage in a state of the charging mode, in which the first threshold voltage is greater than the second threshold voltage.
