重化回路。Two constant voltage power supplies using switching regulators are connected in parallel to the load, and a reverse current blocking diode is inserted between the output bus of one of the regulators and the power supply line, so that one regulator is always in operation. , in a power duplication circuit configured to switch operation from the regulator to the other regulator in the event of an abnormality, a resistor is provided between the anode side of the backflow blocking diode on the output side of each regulator and the other output bus. A capacitor is connected to reduce transient voltage fluctuation during switching, and a diionide is connected between the connection point of the resistor and the capacitor and the cathode side of the backflow blocking diode to discharge the accumulated charge of the capacitor. A power duplex circuit featuring:
