源装置ｉ＆、 ８から制御４源を取っている。(al) Description of the Technical Field The present invention relates to an improved AC power supply device that drives a load having a back electromotive voltage when the main power is lost and restarts it when the power is restored. In an AC power supply device such as a hysteresis motor that drives a load that has a back electromotive voltage when the main power is lost, when restarting from a power outage, information such as the output frequency and output pressure re-starting before the power outage is transmitted when the power is restored. In order to maintain the control circuit until the end of the current period, it is common to obtain the CT source for the control circuit from an uninterrupted TT source device as shown in Figure 1. In the figure, the main circuit of the AC storage source II11 is: i! A power breaker 2 that protects against short circuits within the equipment, an (AC/DC) converter 3 composed of semiconductors such as thyristors or diodes, reactors 4, capacitors 5, semiconductors such as thyristors or transistors, etc. The control circuit 7 is formed by the FI'i-X (DC/AC) converter 6, etc., and is controlled by the uninterruptible power supply 8 installed outside the AC NIIL source device 1. It receives a power supply, controls the (AC/DC) converter 3 and the (DC/AC) converter 6, and builds a load 9, such as a synchronous motor or a hysteresis motor, which has a back electromotive voltage when the generation source is lost! In the device 1 shown in Fig. 1, in order to restart the power outage, it is necessary to hold information such as the output UL number and the output voltage before the power outage in the control circuit 7 until the power outage occurs. For this reason, four control sources are installed from the power supply device i&8 to ensure that the control power supply does not fail even in the event of a power outage.

ことは自明である。[7] The unstoppable W4 momme device 8 is very expensive, and as a result, it has the disadvantage that the total cost of the drive system as shown in FIG. 1 is very high. (C1 Purpose of the Invention The present invention has been made based on the above-mentioned reasons, and is a control power supply device.
It is an object of the present invention to provide an alternating current source system which does not require a sleepless source device and which does not have the above-mentioned drawbacks. (d+ Structure and operation of the invention The present invention will be described below based on an embodiment shown in the drawings. FIG. 2 shows the structure of the present invention, and the main circuit is A control transformer 10 is provided on the power supply side of the main circuit, and a control transformer 11 is provided on the load side of the main circuit, and the secondary output of each control transformer is supplied to the control circuit 7. The rectifier circuit shown in Figure 3 (+- provided, input terminal 12V control transformer 100 secondary output, input yi
ii - Connect the 2eK output of the control transformer 11 to -f-13. Further, a rectifier bridge constituted by diodes I)1 to I)4 rectifies the input from the input terminal 12. A rectifier bridge constituted by a diode Ds%D rectifies the input on the input terminal 13. The input of the input terminals 12 and 13, whichever has the higher It output, is connected to the output 4 child 14 through the diode 0! ~l)1
Selected by □ and output. 1 Climbing detection relay 15
is connected to the output of the rectifier bridge constituted by diodes 1)I to 1) and K, and detects a power outage of the main circuit power supply of the AC power supply unit 1. In such a circuit configuration, if the main circuit 4m is stopped, the human power at the input terminal 12 becomes pulsed and the stoppage detection relay 15 is released, but the load 9 is
Since it has a back electromotive voltage, the human power at the input terminal 13 continues,
The output from the output terminal 14 continues. Even during a power outage, the control '4ta of the control circuit 7 can be ensured, and the power outage detection relay 1
Suspension due to 5 being released! Due to the L@ output, information before the shutdown, such as output frequency and output voltage, is held in the control circuit 7. Within a certain period of time, the main circuit voltage =
When the power is restored, the power outage detection relay 15 returns, and the control circuit 7 controls the (AC/DC) converter 3 and the (IL flow/AC) converter 6 based on the retained information, and prevents the power outage. Perform a reboot. (e) Another embodiment of the invention FIG. 4 shows another embodiment of the invention. That is, FIG. 4 shows that in the control circuit 7 shown in FIG.
In place of the rectifier circuit shown in the figure, the illustrated 11 current circuit is provided, and the input terminal 12 is connected to the secondary output of the control transformer 10, and the input terminal 13 is connected to the secondary output of the control transformer 1]. The voltage relay 16 is connected to the output of a rectifier bridge constituted by diodes 1) 5 to 8, and is turned off at voltage value vR or higher.
If the main circuit power supply, which is probably the N-stop relay, is out of power from time tl to time t2, that is, as shown in FIG. , Stops at time [1, time 1. to detect power restoration. Negative #9 has a back electromotive force during a main power outage, so that the input terminal 13 continues to be powered by human power. However, input terminal 130 solder pressure V
Since the rotational speed of the load 9 decreases with time, L is '
This voltage VL decreases over time as shown in the g5 diagram.
is time 1. As shown in FIG.
．． When the power is turned on, the control circuit 7 returns the information VC held at the time of the power outage.
Based on this, a power outage restart will be performed. In addition, as at time t3, the voltage relay 16Vζ confirms that the pressure is less than a certain forming value, and even if the main power is restored, the control circuit 7 controls so as not to restart the power outage. You can change the method. to Other Embodiments of the Invention FIG. 6 shows an embodiment of the invention according to the present invention.17 In the control circuit 7 shown in FIG. 2, the rectifier circuit shown in FIG. A secondary output of the control transformer 10 is connected to the input terminal 12. A photocoupler 17 and a protective wire 18 are connected to both ends of the input terminal 13. Protection resistance 1
9 is connected, and the output of the photocoupler 17 is input to the 8 wave number detection circuit 20. With this configuration, the main circuit power supply is switched from time t1 to time t! In the case of a power outage, as shown in FIG. 7, the power supply voltage Vs becomes zero from time t1 to time t2, stops at time t+, and detects 1't at time tl. When the 9-load main power supply is interrupted, the input terminals 1 and 3 are switched because of the back electromotive voltage. Here, if the input frequency of the input terminal 13 is fr,
The output of the photocoupler 17, which is input to the frequency detection circuit 201C, becomes a pulse with a 1-second interval.The surrounding wave number detection apposition 20 measures the pulse interval or the number of pulses per supination time and determines the load frequency ft. . During a main power outage, the rotational speed of the load 9 will attenuate over time.
The scatter tL decays over time. Then, as at time t3, this load frequency tL is confirmed to be a certain frequency value fR by the frequency detection circuit 20, and if the main power is restored, the control circuit 7 is held at a certain frequency value fR during the power outage. Based on the information received, the system can be restarted after a power outage. Also, as at time t3, it has been confirmed that the load frequency fL is smaller than a certain frequency value [R, and even if the main 111 is restored, the control circuit 7 can change the control method so as not to restart the power outage. . (gl Overall effect) In this way, the present invention can provide a father-style power source device that uses an expensive uninterruptible power supply as a military equipment as a control ridge source device. It is obvious that the OF variable voltage aJ variable frequency power source device can be applied without being limited to the power source device.
