Abstract

PURPOSE: To check accidental generation of alarm by means of a detection voltage generation circuit provided corresponding to respective power source in such a manner as to allow adjustment of proportional coefficient between the output voltage and the detection voltage of the power source according to the voltage across the diode.
CONSTITUTION: When the load terminal voltage V0 is lower than the output voltage V1 of the power sources 1-1, diodes 3-1 conduct. The interface voltage Va attains the detection voltage of the power sources 1-1, and the differential signal between the reference voltage and the detection voltage is outputted from comparison amplifiers 2-1. The differential signal controls a control transistors 6-1. When the load terminal voltage V0 is higher than the output voltage V1 of the power sources 1-1, the diodes 3-1 are cut off. If the output voltage V1 is kept higher than the alarm detection voltage when the diode is cut off, no alarm is generated. When the power sources 1-1 produces no voltage, there is no alarm.
