  According to the present invention, it is possible to easily output an optimum voltage to the load device according to a change in the load device or the like.

  Hereinafter, a power supply system and a power supply apparatus according to the best embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, in the power supply control system 1 according to the present invention, a power supply device 10, a load device 20 that operates by an output voltage Vout output from the power supply device 10, an input device that operates the power supply device 10, and a display An operator terminal 30 such as a personal computer having an apparatus or the like is connected. In the power supply control system 1, a value representing the state of the load device 20 detected inside the load device 20 is output to the power supply device 10 as load side data D. The power supply device 10 receives the load side data D from the load device 20. Is used to output the optimum output voltage Vout to the load device 20 determined. The operator terminal 30 is used by an operator to input an operation signal.

  The operator terminal 30 need not always be connected to the power supply device 10. Connect only when necessary, such as when changing data.

  In the following description, the power supply device 10 is a radar pulse power supply used for a transmission / reception module of a radar antenna, and the load device 20 is a radar antenna element. However, the power supply device 10 can be applied to various power supply devices. .

  The load device 20 includes an RF amplifier 21 used to execute transmission / reception of pulses, and operates with the output voltage Vout output from the power supply device 10 to execute transmission / reception of pulses. The load device 20 includes a temperature detection unit 22 that detects the temperature of the RF amplifier 21 that affects the operation of the RF amplifier 21, and outputs the temperature detected by the temperature detection unit 22 to the power supply device 10 as load-side data D. To do.

  The power supply apparatus 10 includes a power circuit 11 that outputs the output voltage Vout, a control unit 12 that outputs a reference voltage value Vref that determines the output voltage Vout to the power circuit 11 according to the load-side data D, and setting of the reference voltage value Vref. And a table storage unit 13 for storing a setting table to be used. The power supply device 10 is configured to be capable of digital processing, and executes processing by the control unit 12 by digital processing.

  When the load side data D is input from the load device 20, the control unit 12 refers to the setting table stored in the table storage unit 13 and sets the reference voltage value Vref corresponding to the input load side data D. Further, the control unit 12 outputs the set reference voltage value Vref to the power circuit 11.

  For example, as illustrated in FIG. 2, the table storage unit 13 stores a setting table 131 in which “load side data” and “reference voltage value” are associated with each other. In “load side data”, a range of load side data is defined. Further, the “reference voltage value” is a value that determines the optimum output voltage Vout for the operation of the load device 20 that outputs the load side data D within the range of the associated load side data. In the setting table 131, optimum values are determined for each load-side data range based on ideal values determined by simulation, past output voltage Vout, load-side data D, and the like.

When the setting table 131 shown in FIG. 2 is stored in the table storage unit 13, when the load side data D output from the load device 20 is a value equal to or higher than T ₁ ° C., the control unit 12 displays the reference voltage value. setting the V ₁ to. When the load-side data D output from the load device 20 is a value between T ₂ ° C and T ₃ ° C, the control unit 12 sets V ₂ to the reference voltage value Vref.

  When the reference voltage value Vref is input from the control unit 12, the power circuit 11 converts the input voltage Vin into an output voltage Vout that is optimal for the operation of the load device 20 according to the input reference voltage value Vref, and outputs it.

  The control unit 12 is connected to the operator terminal 30. When an operation signal is input by the operator, the control unit 12 can set the reference voltage value Vref in the control unit 12 based on the operation signal. The table storage unit 13 is also connected to the operator terminal 30, and when an operation signal is input by the operator, a setting table to be stored in the table storage unit 13 is generated based on the operation signal, or the setting table Can also be updated.

  Since the power supply device 10 is configured to be able to perform digital processing as described above, when the operator executes the setting of the reference voltage value Vref and the generation and update of the setting table, a GUI (graphical user interface) in the operator terminal 30 is used. ) Can be easily operated using the function.

  As described above, in the power supply system 1 according to the present invention, the load side data D is used by the control unit 12 and the state of the load device 20 is converted from the reference voltage value Vref set with reference to the setting table 131 by digital processing. The combined output voltage Vout is output. Therefore, even when a change occurs in the load device 20, since the correction of the output voltage Vout is automated using feedback control, it is easily optimized and stable without replacing the components in the power supply device 10. The output voltage Vout thus obtained can be output to the load device 20.

  Further, when the setting table 131 is generated, by using the history such as the past output voltage Vout and the load side data D, the prediction process (the optimum output voltage Vout predicted in accordance with the state change of the load device 20 is obtained). Output processing) and learning processing (processing for outputting the output voltage Vout that was output when the load device 20 was in the same state as the current state) in the past. For example, as shown in FIG. 4 (a), the output voltage may fluctuate. By applying the prediction process or the learning process in combination, as shown in FIG. It becomes possible to suppress. At this time, since the power supply apparatus 10 is digitized, the operator can easily generate and update the setting table 131 using the operator terminal 30.

  In the above-described example, it is assumed that the temperature of the RF amplifier 21 affects the operation of the load device 20, and the temperature of the RF amplifier 21 detected by the temperature detection unit 22 is the load side data D. However, in addition to the temperature of the RF amplifier 21, for example, an output voltage (load end voltage) actually input to the RF amplifier 21 changes in the load device 20, and other states that affect the operation of the load device 20 It may be used as load side data.

  When there is data (power-side data) that occurs in the power supply device 10 and affects the operation of the load device 20, the control unit 12 uses this power-side data to set the reference voltage value. It may be set.

<Modification>
In the example described above, the setting table 131 stored in the table storage unit 13 has a configuration in which “load-side data” and “reference voltage value” are associated with each other, but includes data that can adjust the output voltage. If so, the configuration is not limited. For example, as illustrated in FIG. 3, a setting table 132 in which “load side data” and “reference voltage value change rate” are associated may be stored in the table storage unit 13. This “reference voltage value change rate” is a rule that determines an optimum output voltage for the operation of the load device 20 that outputs the load-side data D within the range of the associated load-side data.

  As illustrated in FIG. 3, when “reference voltage value change rate” is associated with “load side data”, the control unit 12 performs the current determination according to the rule defined by the extracted “reference voltage value change rate”. A reference voltage value Vref is set for the output voltage Vout. For example, the “reference voltage value change rate” may be a numerical value indicating the ratio between the current output voltage and the optimum output voltage Vout, or the output voltage that changes in time series with respect to the current output voltage. It may be a mathematical formula for setting to Vout.

  When the reference voltage value Vref is set using the setting table 131 shown in FIG. 2, as shown in FIG. 5A, the output voltage Vout can only be changed linearly. On the other hand, when the “reference voltage value change rate” is used, the output voltage Vout is controlled to change in time series according to the characteristics of the load device, as shown in FIGS. 5B and 5C. It becomes possible. Therefore, the load device 20 can output the optimum output voltage Vout.
