Abstract
PURPOSE: To attain miniaturization and econimization by using a comparison amplifier in common, by respectively detecting and inputting electric currents, supplied to loads, to the comparison amplifier via OR circuits and then by comparing them with a reference voltage.
CONSTITUTION: A direct current is switched by converter CONV to apply desired constant DC voltages to loads, connected to output terminals OUT1 and OUT2 via transformer T and diodes D1 and D2. Load currents are detected by current detection parts SN1 and SN2, whose detection outputs are passed through OR circuits of diodes D3 and D4 and inputted to comparison amplifier AP, where they are compared with the reference voltage of reference power source VR. If amplifier AP finds one current detection output higher than the reference voltage, the output is applied to converter CONV via isolator IR to droop the output voltage. Therefore, if at least one of loads is short-circuited and an overcurrent is supplied, the output voltage is drooped to suppress the overcurrent, protecting CONV, photodiodes D1 and D2, etc.
