IPC: H02M3/28
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a DC power supply unit capable of protecting by reducing other driving outputs while maintaining control output even under abnormal conditions on a load side. SOLUTION: A driving output part 6 turns off a transistor Q2 when the voltage of driving output is lower than a prescribed level to turn off a Zener diode ZD1. With a resistor R4 and a capacitor C4 connected, the voltage of a non-reversal input terminal becomes lower than that of a reversal input terminal in an operational amplifier 15, a transistor Q3 is turned on by setting the output of the operational amplifier 15 at H level, thereby controlling a dropper IC7 for stopping the driving output. The dropper IC7 stops the driving output, however, an inverter circuit 2 remains operated to leave the control output as it is. The inverter circuit 2 is not affected by another driving output, if any. The output stopping means 12 of the driving output part 6 can continue its operation, thus it is possible to attain proper control.
