この発明は、かかる用途に用いられる電源装置に関する
ものであり、特に一方に対して他方が遅れて立上りまた
早く立下がるというシーケンスを与えられた２つの出力
を持つ電源装置に関する。The present invention relates to a power supply device used for such applications, and particularly to a power supply device having two outputs in which one output is given a sequence in which the other rises later and falls earlier.

で立上がる。６、９はこれら第１、第２の出力が供給さ
れる出力端子である。A conventional circuit configuration of this type of power supply device will be explained with reference to FIG. An input to the power supply device (for example, AC 200 V is applied to input terminal 1. When input to this input terminal 1 (hereinafter referred to as device input) is given, the output of auxiliary power supply circuit 2 rises, and the sequence control circuit 3 becomes ready for operation.The sequence control circuit 3 first turns on the electromagnetic switch 4 either automatically after a certain period of time after the output of the auxiliary power supply circuit 2 rises, or in accordance with a turn-on command given from the outside. The signal is sent, and after a predetermined time, a closing signal is sent to the other electromagnetic switch T. When the device input is input to the stabilized power supply circuits 5 and 8 by closing the electromagnetic switches 4 and T, the respective outputs (first and second outputs) rise with a predetermined time difference. 6 and 9 are output terminals to which these first and second outputs are supplied.
第１、第２の出力を遮断するときには、上と全く逆に、
シーケンス制御回路３からまず電磁開閉器１に遮断信号
が送られついで所定の時間遅れＣ他方の電磁開閉器４に
遮断信号が送られる。When cutting off the first and second outputs, completely opposite to the above,
The sequence control circuit 3 first sends a cutoff signal to the electromagnetic switch 1, and then after a predetermined time delay C, a cutoff signal is sent to the other electromagnetic switch 4.
このように、シーケンス制御回路３によつて電磁開閉器
４、５の投入と遮断のタイミングを制御することにより

題がある。すなわち、一方の安定化電源回路５が故障し

２の出力のみが立上り要求シーケンスを満足できなくな
る。In this way, by controlling the timing of closing and shutting off the electromagnetic switches 4 and 5 by the sequence control circuit 3, the rise of the second output can be delayed and the fall of the second output can be accelerated with respect to the first output. I can do it. However, such a conventional configuration has a problem in that the sequence between the two outputs cannot be maintained in the event of a failure of the stabilized power supply circuit 5, a power outage, or the like. That is, if one of the stabilized power supply circuits 5 fails and is turned on in a state where it cannot supply an output, only the second output will not be able to satisfy the rise request sequence.

点を除去し２出力間のシーケンスの保障をより確実にし
た電源装置を提供することにある。Furthermore, if the stabilized power supply circuit 5 fails during steady operation, only the first output will fall, making it impossible to satisfy the required sequence. Furthermore, if a power outage occurs during normal operation, the
However, the fall time of each output depends on the capacity of the output capacitor in each stabilized power supply circuit 5, 8 and the size of the load connected to the output terminals 6, 9. Due to the disjoint dependencies, the required sequence between outputs may not be followed. SUMMARY OF THE INVENTION An object of the present invention is to provide a power supply device that eliminates the above-mentioned problems and ensures a more reliable sequence between two outputs.

Check the output of the power supply circuit and control the stabilizing power supply circuit in the previous stage.

参照して説明する。The device input is input to the pre-stabilized power supply circuit 8 via the electromagnetic switch 4, and the output of the pre-stabilized power supply circuit 8 is connected to the second
It is connected to the second output terminal 9 as an output. The output of the post stabilized power supply circuit 5 is connected as a first output to a first output terminal 6, and to this output terminal 6 is connected the output of a newly installed parallel power supply circuit 10 for backup. The prestabilization source circuit 8 is connected to the input of the device input and the sequence control circuit 3.
The second output is provided on the condition that a drive signal is input from the drive signal. The operation of this embodiment will be explained with reference to the time chart of FIG.

号が送られ、これにより電磁開閉器４が投入する。When the device input is supplied and the output of the auxiliary power supply circuit 2 rises, a closing signal is sent from the sequence control circuit 3 to the electromagnetic switch 4 automatically or in response to an external command after a certain period of time after the rise. Switch 4 closes.

を出す。The parallel power supply circuit 10 may be an unstable rectifier circuit, and immediately outputs a backup output to the output terminal 6 after the electromagnetic switch 4 is turned on.
supply to. This backup output has a level different from that of the first output, and is set to a level necessary for sequence guarantee. The period during which the second output is guaranteed by this backup output is period 1 in FIG. The sequence control circuit 3 detects the rise of the first output terminal (backup output) and outputs a drive signal after a predetermined time.

２出力が立下がる。When the pre-stabilized power supply circuit 8 receives the drive signal, it raises the second output. Following the rising of the second output, the post-stabilized power supply circuit 5 raises the first output. This period is the third
This is the period indicated by 2 in the figure. In the power-off operation, the sending of the drive signal from the sequence control circuit 3 is cut off, and first the second output falls.

５の具体的構成および両者の出力の接続について第４図
によつて具体的に説明する。As a result, the first output falls, and the first output terminal 6 becomes the backup output level. This is period 3 in FIG. The sequence control circuit 3 detects a drop in the level of the first output terminal 6, and after a predetermined time, sends a cutoff signal to the electromagnetic switch 4 to cut off the input to the device. This makes the first
Output terminal 6 falls. This period is marked 4 in FIG. Here, the specific configurations of the juxtaposed power supply circuit 10 and the downstream stabilized power supply circuit 5 and the connection of their outputs will be specifically explained with reference to FIG.

される一般的な構成である。次に、障害時のシーケンス
の保障について説明しよう。In FIG. 4, a parallel power supply circuit 10 is composed of a transformer 12, a rectifier circuit 13, and a diode 14. This diode 14 prevents a reverse current from flowing to the rectifier circuit 13 side during a period when the first output is being supplied from the downstream stabilized power supply circuit 5. Rear stabilization power supply circuit 5
is a general configuration consisting of a voltage stabilizing circuit 15 and an output capacitor 16. Next, let's explain how to guarantee the sequence in the event of a failure.
例えば、後置安定化電源回路５が故障しても、第１出力
はバツクアツプ出力によつてシーケンス保障上最低限必
要とされるレベルに維持される。For example, even if the post-stabilized power supply circuit 5 fails, the first output is maintained at the minimum level required for sequence guarantee by the backup output.
また停電が生じた場合、まず第２出力が立下がり、つい

ブ信号が出されないため、第２出力も立上がらず、２出
力間シーケンスが保障される。Furthermore, when a power outage occurs, the second output falls first, and then the first output falls. And the rear stabilized power supply circuit 5
Since inputs the output of the pre-stabilized power supply circuit 8, that is, the second output, the sequence between the first and second outputs is determined regardless of the capacitance of the output capacitor of each circuit 5, 8 and the weight or weight of the load on each circuit. is always guaranteed. If the first output terminal 6 does not rise due to a failure of the parallel power supply circuit 10 when the power is turned on, the drive signal is not output from the sequence control circuit 3, so the second output also does not rise, and the sequence between the two outputs is guaranteed. Ru.
以上に述べたように、本発明の電源装置は一部回路の故
障や停電事故等に対するシーケンスの保障が従来よりも
大幅に確実化される。As described above, in the power supply device of the present invention, the guarantee of the sequence against failures of some circuits, power outage accidents, etc. is made much more reliable than in the past.
