The comparator compares the input signal with a threshold level to generate first data, such that each bit of the first data is one of two possible states, and identifies an ambiguous bit of the first data in an ambiguous range. The converter coupled to the comparator converts the first data to parallel. The data check module coupled to the converter evaluates whether the first data is inaccurate according to an error checking code thereof, and changes the ambiguous bit to the other possible state, if the first data is inaccurate. The ambiguous range includes the threshold level.

Abstract: A control circuit for preventing equipment from being damaged by voltage sag uses a modular circuit having a rectifier, an electricity storing device or a control relay to perform functions of charging, discharging, and controlling. The modular circuit can be applied to control circuits of all equipment for increasing stability of the equipment. When a power source of the control circuit has voltage sag, the electricity storing device discharges for assisting a winding of a magnetic switch in riding through a temporary period of demagnetization. Consequently, the main connections keep contact for preventing the power source from being broken and also preventing the equipment from being damaged.
