Reference numeral 19 denotes a power stop/switch circuit that receives the notification from the second alarm circuit 18 and switches between stopping power transmission from the power supply device 1 and starting power transmission to the backup power supply device 8.

Next, the operation of the operating condition stabilizing device for the utilization device having the above configuration will be explained.

First, the operating voltage range of the data processing device 2 is set in the operating condition range setting circuit 3. Then, a variation allowable time is set in the variation allowable time setting circuit 9 when the voltage transmitted from the power supply device 1 to the data processing device 2 fluctuates. Then, the power supply device 1 prepares for power transmission. After this operation is completed, the data processing device 2 is transferred from the power supply device 1 to the data processing device 2.
Start transmitting power to And the operating voltage detection circuit 1
0 detects the voltage during operation of the data processing device 2. Therefore, the second comparison/judgment circuit 11 compares the detected voltage detected by the operating voltage detection circuit 10 with the set value of the operating condition range setting circuit 3, and when the detected voltage is within the set value, the result is positive. Output a signal. The first variable timer operation determination circuit 12 outputs an affirmative signal if an operation timer (not shown) is operating while the second comparison determination circuit 11 is outputting the affirmative signal. Therefore, the variable timer stop circuit 13 is the first variable timer operation determination circuit 12.
When the affirmative signal is input, the operation of a variable timer (not shown) is stopped, and the timer is reset and returned to the operating voltage detection circuit 10. Then, if the operation timer (not shown) is not operating while outputting this affirmative signal, the first variable timer operation determination circuit 12 returns the signal to the operation voltage detection circuit 10. Further, the second comparison/judgment circuit 11 compares the detected voltage detected by the operating voltage detection circuit 10 with the set value of the operating condition range setting circuit 3, and when the detected voltage is outside the set value, a negative signal is sent. Output. Therefore, the second fluctuation timer operation determination circuit 14 is different from the second comparison determination circuit 1.
When a negative signal output from 1 is input, a variable timer (not shown) determines whether or not it is in operation. If it is in operation, it outputs an affirmative signal, and if it is stopped, it outputs a negative signal. Therefore, the variable timer starting circuit 15 is activated by the second variable timer operation determination circuit 1.
When the negative signal of No. 4 is input, a variable timer (not shown) is activated. On the other hand, if this variable timer (not shown) is operating, the second variable timer operation determination circuit 14
A positive signal is output from. This affirmative signal is input to the third comparison/judgment circuit 16. This operation is the same when the variable timer starting circuit 15 starts a variable timer (not shown). Next, the third comparison and determination circuit 16 outputs an affirmative signal to the power supply device control circuit 17 when the display time of the fluctuation timer (not shown) is within the set value of the fluctuation allowable time setting circuit 9. Therefore, this power supply device control circuit 17 performs voltage control to the power supply device 1. On the other hand, when the display time of the variable timer (not shown) is outside the set value of the variable allowable time setting circuit 9, a negative signal is output to the second alarm circuit 18. Therefore, this second alarm circuit 18 operates and outputs a notification signal. This notification signal activates the power stop/switch circuit 19, which stops power transmission to the power supply device 1 currently in use, and also switches the start of power transmission to the backup power supply device 8. Therefore,
The data processing device 2 can be supplied with power from this backup power supply device 8.
