PURPOSE:To decrease the effect due to on/off of a power switch by using a voltage at power supply side of the switch when the switch is turned off and using a voltage of the load side when the switch is turned on as a feedback signal. CONSTITUTION:A DC stabilizing power supply device 3 supplies power to a load 2 via an intermittent switch turned on/off by a signal from an output intermittent signal input terminal 25 in addition to a load 1. When the switch 5 is turned off, a signal switch means 6 gives a voltage at a voltage detecting point P1 at the power supply side from the said switch 5 as a feed back signal S for output voltage stabilization to the DC stabilizing power supply 3. When the switch 5 is turned on, a voltage at a detecting point P2 at the load side from the switch 5 is fed to the DC stabilizing power supply 3 as the feedback signal S. |
