ABSTRACT:
A device for controlling a high voltage to prevent efficiency from dropping by using a detector which detects unstable state of a supply voltage supplied from external circuit and accelerates internal operation of a system in a case that the supply voltage is unstable. The device for controlling the high voltage includes an external voltage detector, a voltage level detector, a generator and a pump.
