Description

  The present invention relates to a power supply apparatus having a plurality of power supplies having different power supply voltage types and current capacities, a power supply method, and a power supply program for causing a computer to execute the method.

  As a power supply system that supplies power to each system load individually from multiple power supplies with different power supply voltage types and current capacities, power is supplied to multi-system loads using a power supply package and a functional package connected to it. There is known a power supply device that supplies power. In such a power supply device, the voltage type and current capacity of each power supply of the power supply package are designed based on the power supply voltage type and current capacity required for the functional package connected to the output side of the power supply package. ing.

  In addition, when designing a power supply device that adds additional functions or other functions to the function package to increase added value, the power supply package is replaced in order to eliminate the waste of developing a new power supply device. Therefore, the design is made so that a new power supply apparatus can be constructed only by exchanging the function package. Furthermore, when designing an additional function package or a power enhancement package, the additional function package or power enhancement package can be added to the pre-designed function package or simply replaced. The power supply package has been designed so that it can be used without being replaced.

  As a power supply method for supplying power to a plurality of loads, a power system is distributed from a power supply board via a power supply relay board (that is, a board corresponding to a functional package), and a plurality of control devices (loads). There is disclosed a power supply device that supplies electric power to (see, for example, Patent Document 1). According to such a power supply device, it is possible to supply power to a load (distributed load) distributed to a plurality of systems from one power supply board and one power supply relay board. Can be planned.

  Moreover, in a parallel power feeding method that supplies power from a plurality of power supply devices connected in parallel to a plurality of terminal devices (loads), a uniform power feeding method that equally divides the total current supplied to all loads by a plurality of power feeding devices. Related techniques are also disclosed (see, for example, Patent Document 2). According to such an equally divided power supply method, the power supply devices can be distributed and distributed while balancing the current capacities and operation modes of the plurality of power supply devices, so that it is possible to improve the space factor such as the installation location of the power supply devices. It becomes possible.

  Further, when power is supplied to a plurality of blade devices (loads) from one common power supply device, each blade device (load) detects the amount of power that can be supplied by the power supply device, and can supply this power amount. There is also disclosed a technique for calculating the amount of power that can be additionally supplied based on the difference between the power consumption value and the total power consumption value, and performing power consumption control of the own blade device (load) (see Patent Document 3). According to this related technology, since each blade device (load) individually controls power consumption, it is not necessary to provide a management controller for managing total power consumption outside, so the wiring of the control system is simplified. be able to.

  However, among the related technologies described above, in the power supply device that supplies power to the multi-system load by the power supply package and the function package, the power supply package is mounted on the power supply package for the voltage and current required by the load. There are cases where the type of power supply voltage is insufficient, or there are restrictions on the wiring pattern, the wiring width, the number of connection pins, etc. for flowing a necessary and sufficient current capacity to the load. In such a case, since the current power supply package cannot be shared, it is necessary to redesign and replace the power supply package.

  In addition, due to the influence of market trends and the like, there may be a change in the specification contents and function contents assumed at the beginning of development. In such a case, a power supply package including a power supply having a power supply voltage type and current capacity different from the previously developed power supply package is required. For this reason, since the power supply package originally developed cannot be shared, the power supply package must be newly developed as well as the function addition package and the function enhancement package. Furthermore, if the power supply method is designed in consideration of the addition of a function addition package or a function enhancement package at the time of initial power supply device development, excessive power supply capacity or the number of power supply pins may occur, or unnecessary power supply Since it is estimated to the pin or a connector with an excessive current capacity is selected, the cost of the power supply device is increased more than necessary.

  In the related art of Patent Document 1, the power relay board connected to the output side of the power board corresponds to a functional package, but this power relay board supplies power below the rated power to each of the distributed loads. However, if the number or capacity of distributed loads increases, it may not be possible to supply desired power to some or all of the distributed loads. That is, when a load different from the power supply voltage type and current capacity assumed in the prior design occurs, it may not be possible to supply power from the power supply relay board to the load.

  Further, in the related technology of Patent Document 2, in a parallel power supply system in which a plurality of power supply devices corresponding to a power supply package are connected in parallel, each power supply device always maintains a balance of supply current even if the load capacity varies. However, since the output voltage of each power supply device is one type, when loads of different power supply voltage types are connected, it is not possible to cope with power supply of this load.

  Furthermore, in the related art of Patent Document 3, a blade device and a load (for example, a processor and a memory) connected to the blade device correspond to a functional package, but each blade device supplies power only to a corresponding load. Due to the configuration, when the load current of a certain blade device increases, it is not possible to supply additional current from other blade devices. In other words, if the blade device is considered to be a functional package, the power supply system of the functional package is divided independently, so that power is supplied from the blade device of the other system even if the load capacity or number of loads of other systems changes. Cannot back up.

  The present invention has been made in view of the above-described circumstances, and even if a change occurs in the number of loads and the voltage current on the load side, a power supply apparatus, a power supply method, and a power supply method that can perform power supply in response thereto, And a power supply program for causing a computer to execute the method.

In order to solve the above problems, a first configuration of the present invention relates to a power supply device that supplies power to each of a plurality of loads having different voltage types to be supplied, and mounts a power source of a plurality of voltage types. An upper power supply unit and a plurality of power supplies mounted on the upper power supply unit are connected to at least one arbitrary power source and receive predetermined power composed of a predetermined voltage type and a predetermined capacity current. A lower power supply unit having a plurality of types of voltage type supply units for supplying to each load of a desired system, and the lower power supply unit corresponds to the voltage and current required by the load. Voltage / current information storage means for storing voltage / current information indicating information of voltage type / current capacity required by the device is provided, and the higher-level power supply unit includes the voltage / current information acquired from the voltage / current information storage means. Based on the above A power supply path selection unit that selects the power source capable of supplying the voltage type / current capacity required by the power supply unit and supplies the power of the selected power source to the corresponding voltage type supply unit of the lower power supply unit; It is characterized by having.

According to a second configuration of the present invention, there is provided a power supply package having a plurality of power supplies, and a plurality of power supplies individually receiving a predetermined power consisting of a predetermined voltage type and a predetermined capacity of current. of a function package to form a voltage-species supply unit, relates to a power supply method for supplying a plurality of pressure-current electricity from the voltage-species supply unit to the load, the function package, the voltage species with its own needs A first step of storing voltage / current information indicating current capacity information, and a voltage type / current capacity required by the functional package based on the voltage / current information acquired from the functional package by the power supply package.

  According to the configuration of the power supply apparatus of the present invention, the power supply package appropriately switches to a power supply system that can supply a desired voltage and current in response to a change in voltage and current required by the functional package, and the desired function package is obtained. Therefore, the power supply package can be shared. Therefore, it is not necessary to develop a power supply package at the time of new development of a function package that occurs in accordance with a load change, so that the design and development costs of the entire power supply apparatus can be reduced.

Embodiment

Hereinafter, an embodiment of the power supply device of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a block diagram schematically showing an electrical configuration of a power supply device according to an embodiment of the present invention. First, the configuration of the power supply device will be described. In the power supply device 1, a power supply package 2 serving as a power supply source and a function package 3 connected to the power supply package 2 and supplying power (voltage / current) to a multi-system load are connected by a connector 4. It has been configured.

  The function package 3 includes information on the supply voltage type (supply voltage A, supply voltage B, supply voltage C, and supply voltage D) required by the function package 3 itself, and information on the current capacity supplied to the load (hereinafter, A voltage / current information storage means 30 for storing these two pieces of information together (referred to as voltage / current information) is provided.

  The power supply package 2 is equipped with three types of power sources A, B, and D, and is requested by the functional package 3 based on the voltage / current information received from the voltage / current information storage means 30 of the functional package 3. The power supply path selection means 20 for selecting a power supply capable of supplying a voltage current to be supplied and supplying a desired voltage current to the functional package 3, and the power supply voltage (first voltage) of the power supply package 2 as the functional package 3 Converters (conversion means) 10 and 11 for converting to a supply voltage (second voltage) required by the device, and supply voltage types (supply voltage A, supply voltage B, supply voltage C, and supply) of the functional package 3 Supply lines 40, 41, 42, 43, and 44 for supplying current for each voltage D) are provided.

  Next, the operation of the power supply system 1 shown in FIG. 1 will be described. The function package 3 requires a supply voltage A, a supply voltage B, a supply voltage C, and a supply voltage D, and a current capacity flowing through the load for each supply voltage type, according to a load side request (not shown). Therefore, voltage current information obtained by combining information on each supply voltage type of supply voltage A, supply voltage B, supply voltage C, and supply voltage D with information on current capacity required for each supply voltage type is voltage It is stored in the current information storage means 30.

  The power supply package 2 is based on the voltage / current information received from the voltage / current information storage means 30 of the function package 3, and the supply voltage type (supply voltage A, supply voltage B, supply voltage C, And the supply voltage D) and the power supply voltage and current corresponding to the current capacity for each supply voltage type are supplied to the functional package 3.

  At this time, the power supply package 2 has a design in which the supply line 40, the supply line 41, the supply line 42, the supply line 43, and the supply line 44 are designed due to restrictions such as a wiring width, a wiring pattern, and the number of connection pins. It is not possible to supply a current that exceeds the current capacity determined by.

  In the example shown in the power supply device 1 of FIG. 1, the function package 3 requires a supply voltage A, a supply voltage B, a supply voltage C, and a supply voltage D, but the supply voltage A, the supply voltage B, and the supply The voltage C can be supplied from the current capacity required by the load through the supply line 40, the supply line 41, and the supply line 42.

  However, for the supply voltage D of the functional package 3, since the current capacity required by the load is large, the current capacity supplied from the power source D through the supply line 44 alone cannot satisfy the current capacity supplied to the load. Therefore, the voltage / current converted from the voltage of the power supply B (first voltage) to the voltage of the power supply D (second voltage) by the converter 11 is supplied from the supply line 43 to the functional package 3 via the power supply path selection means 20. Additional supply to the supply voltage D is provided.

  Regarding the supply voltage C of the functional package 3, since there is no voltage source (power supply C) corresponding to the power supply package 2, the converter 10 converts the voltage from the power supply B to the power supply C, and the power supply path selection means 20 The voltage is supplied from the supply line 42 to the supply voltage C of the functional package 3 via the.

  In the converter 10 and the converter 11, when the power supply B of the power supply package 2 is a direct current voltage and the supply voltage C and the supply voltage D of the functional package 3 are direct current voltages, for example, a booster configured by a switching transistor It can be realized by a type DC / DC converter or a step-down type DC / DC converter, or can be realized by a chopper circuit or a booster circuit. Further, when the power supply B of the power supply package 2 is a DC voltage and the supply voltage C and the supply voltage D of the function package 3 are AC voltages, for example, the converter 10 and the converter 11 can be realized by an inverter. it can.

  When the power supply B of the power supply package 2 is an AC voltage, for example, if a step-up DC / DC converter, a high-voltage DC / DC converter, a chopper circuit, or a booster circuit is passed through a rectifier, the functional package The supply voltage C and the supply voltage D of the functional package can be changed to a DC voltage, and if the inverter is passed through a rectifier, the supply voltage C and the supply voltage D of the functional package can be changed to an AC voltage.

  Next, a description will be given of a case where the function package is changed by changing the specification on the load side in the power supply apparatus. FIG. 2 is a block diagram showing a configuration when the function package is changed from the power supply apparatus shown in FIG. That is, the power supply device 1a shown in FIG. 2 shows a state where the functional package 3 in the power supply device 1 of FIG. 1 is replaced with the functional package 3a. 2 is exactly the same as the power supply package 2 of the power supply device 1 of FIG.

  In FIG. 2, the function package 3a requires a supply voltage A, a supply voltage B, a supply voltage D, and a current capacity flowing through the load for each supply voltage in accordance with a load side request (not shown). Therefore, the voltage / current information storage means includes voltage / current information that combines information on each supply voltage type of the supply voltage A, supply voltage B, and supply voltage D and information on the current capacity required for each supply voltage type. 30.

  The power supply package 2 uses the supply voltage type (supply voltage A, supply voltage B, and supply voltage D) required by the function package 3a based on the voltage / current information acquired from the voltage / current information storage means 30 of the function package 3a. And the current capacity of each supply voltage type is supplied to the function package 3a. At this time, only a predetermined current capacity can be supplied to the supply line 40, the supply line 41, the supply line 42, the supply line 43, and the supply line 44.

  In the case of the example in FIG. 2, the supply voltage A and the supply voltage D can be supplied with current as desired through the current supply line 40 and the supply line 44 from the current capacity required from the load. However, since the current capacity of the supply voltage B is very large due to a request from the load, a desired current cannot be supplied only by the supply line 41.

  Therefore, the power supply package 2 distributes the current from the power supply B by the power supply path selection unit 20 based on the voltage / current information from the voltage / current information storage unit 30 of the functional package 3 a, and functions by the supply line 42 and the supply line 43. It is additionally supplied to the power supply B of the package 3a.

  In this case, the current to the supply voltage B is additionally supplied by the supply line 42 and the supply line 43 because the wiring pattern of the supply line 41 is thin and the wiring capacity is insufficient. Since the current capacity is sufficient, a desired current capacity can be obtained from the power supply B of the power supply package 2 to the supply voltage B of the functional package 3a by the supply lines 41, 42, 43 without using the converter 10 or the converter 11. Can be supplied.

  Note that the converter 10 converts the voltage of the power source B into the voltage of the power source C, and the converter 11 converts the voltage of the power source B into the voltage of the power source D. Since the voltage is not used in the function package 3a, the power supply path selection unit 20 is in a standby state.

  The power supply method described above is realized by a computer reading a program. Therefore, each process of the power supply method described above is stored in a computer-readable recording medium in the form of a program, and each process described above is performed by the computer reading and executing this program. Here, the computer-readable recording medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, and the like. Alternatively, the program may be distributed to an external computer via a communication line, and the computer that has received the distribution may execute the program.

  The power supply device of the present invention is divided into a power supply board and a functional board, and can be adapted to various loads by replacing only the functional board. Therefore, the multi-output power source for communication equipment, broadcasting equipment, large computers, etc. Can be used effectively.
