レーターとを並列に設ける方法も良く用いられる。[Prior Art] Conventionally, as shown in Figure 2, in this type of power supply circuit, separate terminals for drive and control are provided on the secondary side of the transformer, and a switching regulator or the like with high conversion efficiency is installed. Each was provided to stabilize the direct current. Usually, a +24 Vi power source is used to drive motors, relays, etc., and a +5 V power source, which is lower than the power supply voltage of the drive system, is often used as a power source for these control circuits. Furthermore, since the current flowing through the control system is often small, a method is often used in which a switching regulator for driving and a switching regulator for control are provided in parallel at the output of the smoothing circuit, as shown in FIG.
これらの場合、電＃ＯＦＦ時において、第４図に示すよ
うに、駆動系電源より制御系電源の方が早くＯ■近くに
なってしまうため、制御系が動作せず、駆動系が誤動作
することがあった。In these cases, when the power is turned off, as shown in Figure 4, the control system power supply approaches O■ faster than the drive system power supply, so the control system does not operate and the drive system malfunctions. Something happened.
［目 的］
本発明は、前述欠点を除去せんとするもので、電源ＯＦ
Ｆ時に駆動用電源の方が制御用電源よりも早く立ち下げ
、駆動系の誤動作を防ぐことを目的とする。[Purpose] The present invention aims to eliminate the above-mentioned drawbacks, and
The purpose of this is to turn down the drive power supply earlier than the control power supply at F time to prevent malfunction of the drive system.

の平滑回路に人力する。[Example] FIG. 1 shows an example of the present invention. 1 is an AC power supply, for example AClooV, which is input to the transformer 2, the step-down output is rectified by a rectifier circuit such as a diode bridge 3, and the output is rectified by a rectifier circuit such as a diode bridge 4
Human power is applied to the smoothing circuit.

チングレギュレーター５１を用い、電圧を安定化させる
。この出力を駆動系へ接続するとともに、５２の制御系
電圧安定化用スイッチングレギュレーターに接続する。When a large amount of current is required for the drive system, a particularly efficient switching regulator 51 is used to stabilize the voltage. This output is connected to the drive system and also to the control system voltage stabilizing switching regulator 52.
５２はシリーズレギュレーターでも良いが、制御系が多
種多様に亘る場合かなりの電流を流すこともあり、発熱
を防ぐ意味でスイッチングレギュレーターを使用する。52 may be a series regulator, but if the control system is diverse, a considerable amount of current may flow, so a switching regulator is used to prevent heat generation.

動系が無制御になり、誤動作することがある。In the conventional example shown in FIGS. 2 and 3, when switch 6 is opened for a certain period of time, as shown in FIG. 4, the driving voltage is curve a, and the control voltage is curve b. and stand down. Based on the point in time when the switch 6 is opened, the point in time when the drive voltage becomes Ov is set as ta, and the point in time when the control voltage becomes OV is set as tb.

When this happens, the control circuit ceases to operate, and the drive system becomes uncontrolled after t b', which may result in malfunction.
