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; entering a charging mode by transferring the DC power to a load when a voltage of the DC power is equal to or greater than a first threshold voltage; maintaining the load in the charging mode when the voltage of the DC power is equal to or greater than a second threshold voltage in a state of the charging mode; and blocking the DC power to the load when the voltage of the DC power transitions from a voltage higher than the second threshold voltage to a lower voltage less than the second threshold voltage.
