Abstract
A method of controlling power in a wireless power receiver, the method including receiving an AC power via a reception coil, rectifying the AC power to a DC power and controlling the DC power applied to a load by comparing the DC power with a threshold voltage, wherein the controlling the DC power includes measuring a voltage of the DC power, allowing the load to enter a charging mode by transferring the DC power to the load when the measured voltage is equal to or greater than a first threshold voltage, maintaining the load in the charging mode when the measured voltage 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 measured voltage is less than the second threshold voltage.
