Abstract

PURPOSE: To obtain a power supply which provides stable voltage precision output in case that a load is off, by making a comparison between the output of a voltage detector at the load terminal of a constant-voltage power unit and that of a voltage detector at the output terminal of the power unit, and then by applying an error detecting circuit with a voltage proportional to the deviation.
CONSTITUTION: An automatic control circuit which detects output terminal voltage 11 of a constant-voltage power unit, makes a comparison with output voltage setting signal 15, and then applies the deviation to voltage error amplifying circuit 14 is provided with a circuit which compares output terminal voltage 11 with load terminal voltage 12 and inputs voltage signal 13 proportional to the deviation to circuit 14 via switch 16 after putting it in phase. Then when load terminal voltage 12 is released due to a break, etc., of wiring, switch 16 controls the bounce of output terminal voltage 11 of the power unit and while load terminal voltage 12 is detected, it is closed. Even if the detecting circuit of load terminal voltage 12 would be opened, voltage signal 13 is isolated by switch 16 to prevent the output voltage of the power unit from bouncing.
