Fig. 1 schematically shows an application scenario of a data processing device according to an embodiment of the present disclosure.

As shown in fig. 1, a data processing device 10 according to an embodiment of the present disclosure is generally used for data transmission, computation, storage, and the like in application scenarios such as cloud computing, cloud service, cloud storage, big data, deep learning, and the like, and the data processing device includes, for example, a data center.

The data processing apparatus 10 includes a power supply device 100 and a load 200. The power supply device 100 is, for example, configured to receive at least one electrical signal from the outside, and the at least one power supply signal includes, for example, an electrical signal 310 and an electrical signal 320. After the power supply device 100 receives at least one electrical signal, the electrical signal may be correlated and processed, and the processed electrical signal may be output to the load 200 to supply power to the load 200.

In an embodiment, each of the electrical signals from the outside may include an electrical signal from a commercial power supply or an electrical signal from a diesel generator.

Each of the electric signals from the outside may be an alternating current signal having a voltage value of, for example, 10.5 kV. When an ac signal having a voltage value of 10.5kV is input to power feeding apparatus 100, power feeding apparatus 100 performs a step-down operation on the ac signal having a voltage value of 10.5kV, and the voltage value of the ac signal obtained after the step-down operation is 220V, for example. Next, the power supply device 100 outputs an ac signal having a voltage value of 220V to the load 200 to supply power to the load 200.

However, since different external electrical signals have phase differences, for example, the electrical signal 310 and the electrical signal 320 have phase differences, a plurality of ac electrical signals (having a voltage value of 220V) obtained by performing voltage reduction operations on the plurality of electrical signals cannot be connected to one bus, and therefore, the plurality of ac electrical signals need to be respectively output to the load 200 through the plurality of buses, which results in a large number of buses and redundancy. The bus bar is, for example, a cable, and the bus bar for transmitting the ac electrical signal has a large radius and generates a large amount of heat, which results in energy consumption. In addition, the alternating current signal with the voltage value of 220V is obtained by carrying out voltage reduction operation on the alternating current signal with the voltage value of 10.5kV, the efficiency of the voltage reduction operation process is low, and the electric energy consumption is large. In the process that the power supply device 100 transmits the ac signal with the voltage value of 220V to the load 200 for power supply, the misoperation of the operator easily generates a ground loop, thereby causing danger to the personnel of the operator.

In view of this, embodiments of the present disclosure provide a power supply device and a data processing apparatus. The power supply device comprises a direct current conversion module and an output module. The direct current conversion module is configured to adjust the output power of the direct current conversion module according to the power of an external load based on a preset strategy; the direct current conversion module comprises a plurality of conversion sub-modules, each conversion sub-module comprises an input end and an output end, and each conversion sub-module is configured to convert an alternating current signal received at the input end into a direct current signal and output the direct current signal from the output end. And the output module is electrically connected with the direct current conversion module and is configured to receive the direct current electric signals output by the conversion sub-modules so as to supply power to an external load. In addition, the data processing device comprises a load and a power supply. The power supply device and the data processing apparatus of the embodiment of the present disclosure will be described below with reference to fig. 2 to 12.

Fig. 2 schematically illustrates a schematic diagram of a power supply device according to an embodiment of the present disclosure.

As shown in fig. 2, the power supply device 100 of the embodiment of the present disclosure includes, for example, a dc conversion module 110 and an output module 120. AC shown in fig. 2 represents an alternating current signal and DC represents a direct current signal.

Illustratively, the dc conversion module 110 is configured to adjust the output power of the dc conversion module 110 according to the power of the external load based on a preset strategy.

For example, the dc conversion module 110 is configured to receive an ac electrical signal from the outside. After the dc conversion module 110 receives the ac electrical signal from the outside, the dc conversion module 110 may adjust the output power of the dc conversion module 110 according to the power of the external load based on a preset strategy, so that the output power of the dc conversion module 110 matches the power of the external load. Illustratively, the power of the external load may include, but is not limited to, a rated power.

The dc conversion module 110 may include a plurality of conversion sub-modules, for example, the dc conversion module 110 includes a conversion sub-module 111 and a conversion sub-module 112. Each conversion submodule includes an input and an output, and each conversion submodule is configured to convert an alternating current signal received at the input of the conversion submodule into a direct current signal and output the direct current signal from the output of the conversion submodule.

Illustratively, the number of the plurality of conversion submodules matches the number of the alternating current signals from the outside. Taking the example that the ac electrical signal from the outside includes the ac electrical signal 310 and the ac electrical signal 320, the conversion submodule 111 converts the ac electrical signal 310 received at the input terminal into a dc electrical signal and outputs the dc electrical signal from the output terminal, and the conversion submodule 112 converts the ac electrical signal 320 received at the input terminal into a dc electrical signal and outputs the dc electrical signal from the output terminal.

The output module 120 is electrically connected to the dc conversion module 110, and the output module 120 is configured to receive the dc electrical signals output by the plurality of conversion sub-modules to supply power to an external load.

Illustratively, the output module 120 is electrically connected to the output of each conversion submodule, and the dc signal from the output of each conversion submodule is input to the output module 120. The output module 120 outputs the dc signal to an external load to supply power to the external load.

According to an embodiment of the present disclosure, the power supply device supplies power to the external load by converting an alternating current signal from the outside into a direct current signal. The direct current signal supplies power to the external load, so that the consumption of electric energy is reduced, the conversion efficiency of the electric signal is improved, and the personal safety of operators is guaranteed. In addition, the power supply device can adjust the output power according to the power of the external load based on a preset strategy, so that the output power is matched with the power of the external load, and the flexibility of power adjustment is further realized under the condition that the power meeting the requirement is provided for the external load.

Fig. 3 schematically illustrates a schematic diagram of adjusting output power according to an embodiment of the present disclosure.

As shown in fig. 3, the power supply device 100 of the embodiment of the present disclosure includes, for example, a dc conversion module 110 and an output module 120. The dc conversion module 100 includes N conversion submodules, where N is an integer greater than 1. The dc conversion module 110 may adjust the output power of the dc conversion module based on a preset policy and according to the power of the external load, so that the output power of the dc conversion module matches the power of the external load.

For example, the preset policy includes: when the input power of the N conversion sub-modules is greater than or equal to P/N, the N output powers of the N conversion sub-modules are equal to each other and the sum of the N output powers is equal to P, where P is the value of the power of the external load and the unit of the power may be watt or joule.

For example, taking the example that the N conversion sub-modules include the conversion sub-module 111 and the conversion sub-module 112, that is, N is 2, and the power of the external load is, for example, P. First the input power P of the conversion submodule 111 is determined_{input_1}Whether it is greater than or equal to P/2, and determining the input power P of the conversion submodule 112_{input_2}Whether it is greater than or equal to P/2. If the input power P of the conversion submodule 111 is_{input_1}Greater than or equal to P/2 and converts the input power P of the submodule 112_{input_2}Greater than or equal to P/2, the conversion submodule 111 converts its own output power P_{output_1}Adjusted to P/2, the conversion submodule 112 converts its own output power P_{output_2}Adjusted to P/2. I.e. the output power P of the conversion submodule 111_{output_1}And the output power P of the conversion submodule 112_{output_2}Are each P/2, and the sum (P) of the output power of the conversion submodule 111 and the output power of the conversion submodule 112_{output_1}+P_{output_2}) Equal to the power P of the external load.

In an embodiment of the disclosure, the power supply device may adjust the output power of each conversion sub-module according to the power of the external load based on a preset strategy, so that the output power of the dc conversion module matches the power of the external load. For example, when the input power of each conversion sub-module is large, the external load can be provided with equal power through each conversion sub-module, thereby realizing further flexibility of power adjustment based on the power required by the external load.

Fig. 4 schematically illustrates a schematic diagram of adjusting output power according to an embodiment of the present disclosure.

As shown in fig. 4, the power supply device 100 of the embodiment of the present disclosure includes, for example, a dc conversion module 110 and an output module 120. The dc conversion module 110 includes N conversion sub-modules, where N is an integer greater than 1. The dc conversion module 110 may adjust the output power of the dc conversion module based on a preset policy and according to the power of the external load, so that the output power of the dc conversion module matches the power of the external load.

For example, the preset policy may include: when the input power of N conversion sub-modules in the N conversion sub-modules is smaller than P/N, the output power of the N conversion sub-modules is adjusted, so that the output power of each of the N conversion sub-modules is the same as the input power, and the sum of the N output powers is equal to P, wherein N is an integer which is greater than or equal to 1 and less than or equal to N, and P is the value of the power of an external load.

For example, taking the example that the N conversion sub-modules include the conversion sub-module 111 and the conversion sub-module 112, that is, N is 2, and the power of the external load is, for example, P. First the input power P of the conversion submodule 111 is determined_{input_1}Whether it is greater than or equal to P/N, i.e., P/2, and determining the input power P of the conversion submodule 112_{input_2}Whether it is greater than or equal to P/2. If the input power of n of the

conversion sub-modules

111 and 112 is less than P/2, the n conversion sub-module input power is taken as the output power of the conversion sub-module.

For example, n is 1, that is. If the input power P of the conversion submodule 111 is_{input_1}Less than P/2, input power P of the conversion submodule 112_{input_2}Greater than or equal to P/2, the output power P of the submodule 111 will be converted_{output_1}Adjusted to be equal to P_{input_1}Equality, i.e. converting the output power P of the submodules 111_{output_1}Equal to the input power P of the conversion submodule 111_{input_1}. At this time, the output work of the submodule 112 will be convertedRate is adjusted to P_{output_2}，P_output_{_2}E.g. less than or equal to P_{input_2}. I.e. the output power P of the conversion submodule 111_{output_1}And the output power P of the conversion submodule 112_{output_2}Of (P)_{output_1}+P_{output_2}) Equal to the power P of the external load.

In an embodiment of the disclosure, the power supply device may adjust the output power of each conversion sub-module according to the power of the external load based on a preset strategy, so that the output power of the dc conversion module matches the power of the external load. For example, when the input power of the conversion sub-module is small, the power of the conversion sub-module having the small input power is preferentially used. It can be appreciated that by embodiments of the present disclosure, further flexibility in power regulation is achieved on the basis of providing external loads with power that meets the demand.

The dc conversion module 110 includes, for example, a conversion sub-module 111 and a conversion sub-module 112.

The ac electric signals from the outside include, for example, ac electric signals 310 and 320. The voltage value of the alternating current signal 310 and the voltage value of the alternating current signal 320 are both 10.2kV, for example.

Illustratively, the conversion submodule 111 includes a plurality of power cells connected in series, and the conversion submodule 112 also includes a plurality of power cells connected in series. The power unit is, for example, a high-voltage inverter component that performs rectification, filtering, and inversion using power electronics.

Illustratively, the converting submodule 111 converts the ac electrical signal 310 into a dc electrical signal with a voltage value of 750V, and the converting submodule 112 converts the ac electrical signal 320 into a dc electrical signal with a voltage value of 750V.

Illustratively, the converting submodule 111 outputs the dc signal with the voltage value of 750V to the output module 120, and the converting submodule 112 outputs the dc signal with the voltage value of 750V to the output module 120, and the output module 120 includes, for example, a dc bus. Then, the ac signal is transmitted to an external load through the dc bus.

According to the embodiment of the disclosure, the direct current bus for transmitting the direct current electric signal with the voltage value of 750V has a large transmitted voltage value, so that the direct current bus is thin, the loss of the direct current bus in the process of transmitting the electric signal is small, and the cost of the direct current bus and the transmission loss of the electric signal are reduced. In addition, the voltage value of the direct current signal is 750V, and power supply for a high-power load is realized through the direct current bus.

Illustratively, the at least one first voltage-reducing module is configured to reduce the dc power signal from the output module 120 to obtain a first dc power signal, and output the first dc power signal to the load module. For example, if the voltage value of the first dc signal required by the load module is 90V, the at least one first voltage-reducing module reduces the dc signal (voltage value is 750V) from the output module 120 to obtain the first dc signal with a voltage value of 90V.

When the 3 first voltage reduction modules all work normally, each first voltage reduction module can reduce the voltage of the direct current signal with the voltage value of 750V to the voltage of the direct current signal with the voltage value of 30V, and the output of the 3 first voltage reduction modules is the first direct current signal (the voltage value is 90V) required by the load module. When 1 first voltage reduction module is abnormal, each first voltage reduction module in the remaining 2 first voltage reduction modules can reduce the direct current signal with the voltage value of 750V into a direct current signal with the voltage value of 45V, and the output of the 2 first voltage reduction modules is the first direct current signal (with the voltage value of 90V) required by the load module.
