The circuit is composed of mains power, power switch, working power supply, backup power supply, power failure detector, regulator and load. L and N are the live wire and neutral wire of the mains. SW1 is the power switch. Resistor R1, capacitor C1, diode D1, capacitor C3, voltage regulator diode DZ1, and capacitor C4 form a RC step-down working power supply, which provides power for regulators, power failure detectors, and backup power supplies.
