Abstract
PURPOSE:To obtain a power-supply device to prevent faults from being caused, by generating the output of a specified time and forbidding signal from the OFF-suggestion of a power switch, and by preventing a power source from being made immediately after the power source is interrupted. CONSTITUTION:When a power switch is turned OFF, then clock from an AND circuit 9 is fed to the clock input end of an FF circuit 10, and the output of control signal is not to be generated from the FF 10. Accordingly, by a controlling thyristor 1, the feed of output voltage from an AC power source is interrupted, and the output of line voltage is not to be generated from switching circuits 3, 4. Besides, the reset output of the FF circuit 10 is fed to the clock input end of a monostable multi-vibrator 11, and is started. Then, by the output of the monostable multivibrator 11, the gate of the AND circuit 9 is closed for a fixed time. Then, even if the power switch 6 is made, pulse due to its making is interrupted by the AND circuit 9, and in a state that the FF circuit 10 is reset, the output of the control signal is not directed to the controlling thyristor 1 from the FF circuit 10.
