Abstract: To provide a power failure detection system including a voltage regulator that houses a neutral wire of a primary power source that provides alternating current (AC) power and one of three phase wires, a sensing block containing a neutral wire of the primary power source and including a coupled inductor device and a voltage sense amplifier, and a secondary power source.SOLUTION: A voltage regulator is coupled to a switch and generates a direct current (DC) voltage signal. A coupled inductor device of a sensing block includes a pull-down resistor, which converts a voltage signal of the neutral wire into a voltage signal of the neutral wire in which the phase is shifted by 180 degree, and generates a reference voltage signal by using the pull-down resistor. The voltage sense amplifier amplifies a voltage difference between the voltage signal of the neutral wire in which the phase is shifted by 180 degree and the reference voltage signal. The sensing block detects the phantom voltage for one of three phase wires during the power failure period and provides an output signal corresponding to a secondary power source.SELECTED DRAWING: Figure 1
