Abstract
PURPOSE: To carry out performance tests automatically and rapidly, by changing the output voltage of a voltage converter by means of a control circuit, and by deciding the non-defectiveness or defectiveness of the operation of overvoltage and low- tension detecting circuits by the comparison detecting levels of the detecting circuits.
CONSTITUTION: Reference voltage in a reference voltage source 19 is high set by means of a control circuit 18 in order to carry out an overvoltage performance test. The output voltage of a voltage converter 2 is brought to an overvoltage condition, applied to comparators 5, 6 and compared with reference voltage for detection from reference voltage sources 7, 8. Thus, a comparison detection level of the comparator 5 alters, and that of the comparator 6 does not vary, but the operation of the comparator 5 can be identified by decision-treating the conditions of these comparison detecting levels by means of the control circuit 18. When executing a low-tension performance test, the reference voltage of the reference voltage source 19 may low be set.
