And through the ventilation design of the power supply bridge frame, the fan of the server system is utilized for heat dissipation treatment, so that the additional fan system is not required to be added, and the occupied space of the server power supply system in the server can be reduced.
Fig. 1 is a server power supply system according to an embodiment of the present invention, and as shown in fig. 1, the server power supply system includes:
the power supply bridge 101 is disposed on one side of the motherboard of the server.
In the embodiment of the invention, in order to facilitate the close contact between the power supply system and the motherboard, the power supply bridge 101 may be disposed on one side of the motherboard of the server, thereby helping to reduce the loss of power supply consumption. For example, the power bridge may be disposed on the front surface of the motherboard, or the power bridge may be disposed on the back surface of the motherboard. The server may be any server that can function normally, for example: 1U server, 2U server, 3U server. The number of central processing units (Central Processing Unit, CPU) in the server may not be limited. Preferably, the server may be a 2U server comprising 2 CPUs.
The power supply module 102 is fixed on the power supply bridge 101; the power supply module 102 has a power input terminal for connection to a power source and a first output terminal for outputting a first preset voltage.
In the embodiment of the invention, the power supply module 102 is fixed on the power supply bridge 101, the power supply bridge 101 can support the placement of the power supply module 102, and the wires in the power supply module 102 can be reasonably routed through the power supply bridge 101, so that the occupied space of the wires in the power supply module 102 can be reduced.
The power module 102 has a power input and a first output. The power input end is used for being connected with a power supply to receive a power supply voltage provided by the power supply. A first voltage conversion circuit module is included in the power supply module 102. The output end of the first voltage conversion circuit module is a first output end. The first voltage conversion circuit module is configured to convert an input first input voltage into a first preset voltage output by the first output terminal 1020.
In some examples, the power supply module 102 may receive, through a power input terminal, a voltage provided by a power supply to obtain a commercial power (power frequency alternating current, AC), and further perform a voltage conversion process through the power input terminal to obtain a first input voltage. The first input voltage is input into the first voltage conversion circuit module to obtain a first preset voltage, and the first preset voltage is output through the first output end.
For example: when the voltage provided by the power supply is 220 volts (V), the power supply input end converts the received 220V voltage into a first input voltage, and then the first input voltage is input into the first voltage conversion circuit module, so that a first preset voltage (12V) is obtained and is output through the first output end to supply power to the main board. In one example, the power input may convert the input voltage to a first input voltage based on a predetermined alternating current to direct current (AC-DC) power strategy. In another example, the power input terminal includes a high capacitance capacitor, which can provide a longer hold time (hold up).
The connector 103 is arranged between the power supply bridge 101 and the main board; the connector 103 has an input side a connected to the first output terminal and an output side b connected to the power supply terminal of the main board.

The input side a of the connector 103 is connected with the first output end, the output side b is connected with the power end of the motherboard, and the power supply module 102 and the motherboard can form a loop through the connector 103, so that a first preset voltage output by the first output end can be input into the motherboard to supply power to the motherboard.
According to the server power supply system provided by the embodiment, the power supply module is fixed on the power supply bridge, the power supply bridge is arranged on one side of the server main board, the connection distance between the power supply module and the server main board can be shortened, and when the first output end of the power supply module is connected with the main board through the connector to supply power for the main board, the interference of the internal resistance of an electric wire can be reduced, so that the problems of electromagnetic interference, signal abnormality and the like can be effectively reduced. And through the ventilation design of the power supply bridge frame, the fan of the server system is utilized for heat dissipation treatment, so that the additional fan system is not required to be added, and the occupied space of the server power supply system in the server can be reduced.
In some alternative embodiments, the motherboard includes a first component to be powered and a second component to be powered. The power module 102 also has a second output 1021 and a third output 1022; the second output end 1021 is used for outputting a second preset voltage so as to supply power for the first part to be powered through the second preset voltage; the third output terminal 1022 is configured to output a third preset voltage, so as to supply power to the second component to be powered through the third preset voltage; the third preset voltage is smaller than the second preset voltage, and the second preset voltage is smaller than the first preset voltage.
Specifically, the first part to be powered and the second part to be powered can be understood as parts on the main board, which need an external power supply for power supply. The first part to be powered corresponds to the required power supply voltage and is a second preset voltage. The second power supply voltage corresponding to the required power supply voltage of the second power supply part is a third preset voltage. To enhance the reusability of the server power system, the power module 102 further includes a second output 1021 and a third output 1022. The second output terminal 1021 is configured to output a second preset voltage to supply power to the first component to be powered through the second preset voltage. The third output terminal 1022 is configured to output a third preset voltage to supply power to the second component to be powered through the third preset voltage.
In some examples, the power supply module 102 further includes a second voltage conversion circuit module and a third voltage conversion circuit module. The output end of the second voltage conversion circuit module is a second output end 1021, and the second voltage conversion circuit module is used for converting the received second input voltage into a second preset voltage so as to be output by the second output end 1021 and further supply power for the first part to be powered. The output end of the third voltage conversion circuit module is a third output end 1022, and the third voltage conversion circuit module is configured to convert the received third input voltage into a third preset voltage, so that the third output end 1022 outputs the third input voltage, and further power is supplied to the second component to be powered.
In other examples, the input ends of the first voltage conversion circuit module, the second voltage conversion circuit module and the third voltage conversion circuit module are all the first voltage conversion circuit module, so that a single-group primary input and multiple groups of secondary output framework models can be formed, the overall design and the framework design between the main boards can be enhanced, and the system combination of the main board server and the power supply system is realized. And moreover, by adopting a mode of single input and multiple groups of output, the power supply matching can be performed according to the current power consumption by controlling the output and the input module, so that the highest output efficiency is achieved, and the power supply mode is more flexible and efficient.
In other examples, the input end of the second voltage conversion circuit module is the first output end, and the input end of the third voltage conversion circuit module is the second output end 1021, so that a step-by-step voltage reduction mode is adopted to obtain the preset voltage corresponding to and output by each output end. For example: taking the first preset voltage as 12V, the second preset voltage as 5V and the third preset voltage as 3.3V as an example. The first output end inputs the output first preset voltage into the input end of the second voltage conversion circuit module, and the second preset voltage (5V) is obtained through the voltage conversion processing of the second voltage conversion circuit module, so that the output can be further output through the second output end 1021. The second output end 1021 may input the output second preset voltage to the input end of the third voltage conversion circuit module, and obtain a third preset voltage (3.3V) through voltage conversion processing of the third voltage conversion circuit module.
In some alternative embodiments, the power bridge 101 is disposed in a central location within the server interior; the first output end is arranged in the central area of the power supply bridge 101; the second output end 1021 is arranged in a first area of the power supply bridge 101, wherein the first area is an area corresponding to a first position, and the first position is a position of a first part to be powered on a main board; the third output end 1022 is disposed in a second area of the power supply bridge 101, where the second area is an area corresponding to a second position, and the second position is a position of the second component to be powered on the motherboard; the first region and the second region are adjacent to the central region. The first output end, the second output end 1021 and the third output end 1022 are fixed on the power supply bridge in a partition setting mode, so that line loss is reduced, load is balanced, and stability and electromagnetic compatibility (Electromagnetic Compatibility, EMC) anti-interference capacity of the power supply system module are improved.
In other alternative embodiments, the second output terminal 1021 and the first part to be powered may be connected by a wire connection, so that when the first part to be powered is powered, targeted power supply can be performed to meet the power consumption requirement of the first part to be powered. The third output end 1022 and the second component to be powered can be connected in a line connection manner, so that when the second component to be powered is powered, targeted power supply can be performed, and the power consumption requirement of the second component to be powered is met.
In still other alternative embodiments, the number of the second output terminals 1021 is the same as the number of the first components to be powered, and the number of the third output terminals 1022 is the same as the number of the second components to be powered, so that independent power supply can be performed in a one-to-one manner, so as to ensure the reliability and stability of power supply. Moreover, by adopting the mode for power supply, a power supply protection isolation mechanism can be formed, so that when one power supply circuit is abnormal, the power supply circuit can be cut off in time, and the normal power supply of other power supply circuits is not influenced.
In some alternative implementation scenarios, the output ports on the power supply module 102 are not limited to the first output 1023, the second output 1021, and the third output 1022, and may be increased according to actual requirements. When the power supply module 102 has a plurality of output terminals for outputting different preset voltages, the power supply module can supply power to a plurality of components to be powered on the motherboard according to the preset voltages and the output power consumption output by the output terminals. For example: as shown in fig. 2, the power supply module 102 includes a power input I, a first output 1023, two outputs a, two outputs B, and one output C. Wherein the preset voltage output by the output end A is 3.3V, and the output power consumption is 500 watts (W). The preset voltage output by the output end B is 12V, and the output power consumption is 1000W. The preset voltage output by the output end C is 5V, and the output power consumption is 500W. The plurality of power supply components on the main board include: 4 graphic processors (Graphics Processing Unit, GPU) of the back-end network card and PCIE interface of the server, the corresponding power consumption is 350 watts (W); two CPUs with corresponding power consumption of 350W; the fan group and PCIE equipment behind the server supply power, and the corresponding power consumption of components such as a network card, a disk array (Redundant Arrays of Independent Disks, RAID) card and the like is less than 500W. Because the GPU has higher performance requirements for electronic data peak processing (Electrical Date Peak Processing, EDPP), 4 graphics processors of the back-end network card and PCIE interface of the server can be powered by the 12V preset voltage correspondingly output by the two output ends B. By adopting the mode for power supply, higher output capacitance protection can be provided, and meanwhile, the design of two paths of output can isolate the power supply condition of two paths of two GPUs. When the power supply of one path of GPU is abnormal, the power supply of the path of GPU can be cut off in time, and meanwhile, the power supply of the other path of GPU is not influenced. In addition, the power supply module 102 is built by adopting a single-group primary input and multiple groups of secondary outputs, the capacitance value of the primary capacitor at the power supply input end is larger, and two paths of independent power supplies of 12V are respectively adopted at the same time, so that the power consumption requirement of each GPU can be met, and the power supply efficiency is improved.
Because the power consumption of the CPU is greater than or equal to 350W in the running process and the CPU also has higher EDPP requirement, two paths of CPUs can be respectively powered by 3.3V preset voltage correspondingly output by the two output ends A so as to meet the application requirements of the CPUs in various power consumption scenes.
And 5V preset voltage correspondingly output by the output end C is used for supplying power to the fan group and PCIE equipment at the rear of the server, and the network card, the RAID card and other components are used for supplying power to meet the normal operation requirements of the components.
In some alternative embodiments, the connector is a golden finger connector, and the golden finger connector is perpendicular to the plane of the main board. As shown in fig. 3, the power is supplied to the main board 10 by using a golden finger, and the power can be supplied to the components to be supplied on the main board 10 by using a direct insertion mode, so that the independent assembly of the power supply bridge frame and the change of modules with different power segments can be realized. When the golden finger is connected with the main board, the golden finger can be connected with the power supply copper bar on the main board. Because the size of the power supply copper bar is larger, when the main board is powered, the overcurrent capacity of large current can be enhanced, the power supply efficiency is improved, the high-efficiency energy-saving circulation capacity is further enhanced, and meanwhile, the loss of current energy transmission can be reduced.
In other alternative embodiments, the motherboard includes a plurality of central processing units, and in order to facilitate heat dissipation by using a fan of the server system, the golden finger connector may be connected to a power supply flat cable among the plurality of central processing units.

In other optional implementation scenarios, the server system is powered by inserting a golden finger into the middle of a plurality of central processing units according to the liquid cooling system, so that seamless access and use can be realized, and the space layout of the server is not required to be adjusted.
