[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply system used for exciting an electromagnet such as a synchrotron.

[0002]

2. Description of the Related Art FIG. 4 shows a configuration diagram of a conventional power supply system. A computer 1 for creating an output pattern of a power supply device, a timing board 2 for managing the time of a change in the output pattern, a pattern memory tube 3 having an output pattern data storage means 3A, and a power supply device 4 The system is configured by and the output power is supplied to the load 5. The power supply device 4 is composed of a power supply control unit 4A and a power supply output unit 4B.

The control method of the power supply device 4 is as follows. The output pattern is created by the computer 1, and is stored as the pattern data transmission signal 11 in the pattern data storage means 3A in the pattern memory board 3. A timing signal 12 is sent from the timing board 2 to the pattern memory board 3 at the start of the pattern operation, and the output reference value 13A is set at the power control unit 4 of the power supply device 4 at the time intervals controlled by the signal 12.
It is sent to the output reference receiving means 6A in A. The output reference value 13A is sent to the output control means 8 as the output reference value 14A. The output control means 8 controls the output 17 from the power supply output section 4B by the output control signal 16. At this time, the output 17 may be monitored and captured as the output monitor signal 18 to perform feedback control.

By the way, in the conventional pattern control power supply system, as shown in FIG. 2, the output pattern is in accordance with the pattern determined before the operation. In other words, during pattern operation, output 21 can be controlled during pattern operation, but after pattern operation is completed, output 22 at the end of pattern operation can only be maintained. . That is,
Adjustment after the start of operation was impossible.

[0005]

As described above, the conventional power supply system has a disadvantage that the power supply output cannot be controlled after the completion of the pattern operation.

Therefore, the present invention supplies a power supply system capable of controlling the power output even after the completion of the pattern operation, while maintaining the advantage of the conventional pattern control power supply that the output control operation of the constant pattern can be performed at high speed. The purpose is to do.

[0007]

In order to achieve the above object, the present invention takes the following means.

That is, the power control unit is provided with two systems of output reference receiving means, one receives the output reference signal from the pattern memory board and the other receives from the computer. Further, by providing a selecting means for selecting one of these signals between the output reference receiving means and the output control means of the two systems, the operation according to the output pattern received from the pattern memory board during the pattern operation. After the pattern operation is completed, the power output can be controlled by selecting the reference signal from the computer.

[0009]

By the above means, it is possible to construct a power supply system having a high-speed and highly accurate pattern operation function and a real-time adjustment function from a computer in the power supply system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the configuration of an embodiment of the present invention. The power supply control unit 4A in the power supply device 4 includes two reference signal receiving means 6A and 6B. One reference signal receiving means 6A receives the output reference value 13A from the pattern data storing means 3A in the pattern memory board 3, and the other reference signal receiving means 6B receives the output reference value from the computer 1. Receive 13B. Two output reference signals 13A, 13B
Is input to the selection means 4A which selects either one of the output standards. The selection means 7A is a selection signal from the computer 1.
One is selected by 19 and the output control means 8 is notified as an appropriate output reference signal 15. In some cases, the selection signal may be input from the pattern memory board 3.

FIG. 2 shows changes in the output of the power supply system according to this embodiment. In this case, the output reference value 13A from the pattern memory 3 is specified by the selection signal 19 during the pattern operation, and the high-speed and high-accuracy pattern operation output.
You get 21. When the pattern operation is completed, the output reference 13A from the pattern memory board 3 is held at the value immediately before the stop of the timing signal 12. After that, the selection signal 19 is switched to select the output reference value 13B from the computer 1, so that the output can be set to any value within the range permitted by the function of the power output unit 4B of the power supply device 4 via the computer 1 as shown by the output 22. You can get the output of In this way, the conventional power supply system could not control the power output after the pattern operation.
According to this embodiment, control can be performed by giving an output reference value from a computer.

(Other Embodiment) In the embodiment shown in FIG. 3, after the output reference signal 13A from the pattern memory board 3 and the output reference signal 13B from the computer 1 are received by the output reference receiving means, the adding means is added. 7B, the added value is given to the output control means 8 as the output reference value 15. Also in this embodiment, it is possible to control the power supply output shown in FIG.

[0014]

As described above, according to the present invention, it is possible to provide a power supply system having both a high-speed and high-precision pattern operation function by a pattern memory board and a real-time control function by a computer.
