An automatic gain correction circuit is provided to maintain level change of an output terminal by maintaining the comparison operation of a comparator stably by changing an operation of a correction unit according to the ripple change. A comparator(2) receives power level of an output terminal to provide the power to a load side and outputs a change signal that is a difference value by comparing a reference voltage with the power level. A change signal transmission unit(3) operates according to the change signal outputted from the comparator and provides the change signal to an additional controller to control a power level. A corrector corrects the gain and phase of the comparator. An automatic correction circuit corrects the phase of the comparator by changing the gain and phase of the corrector. |
