Description

Technical Field

[0001] This invention relates to the field of power supply technology, specifically to a compatible power supply module and server. Background Technology

[0002] In products such as servers, as GPU components are continuously upgraded, their power consumption is constantly increasing. In traditional 12V power supply scenarios, the current is constantly rising, causing significant voltage drop losses and heat generation, which seriously affects the design of server products. Therefore, in some high-power GPU applications, GPU power supplies have begun to try using 54V as the input voltage. This reduces the voltage drop for the same power, greatly reducing design complexity and losses, and also achieving benefits in areas such as energy saving and carbon neutrality.

[0003] However, components such as CPUs, DIMMs, and HDDs in server products still use 12V voltage as input. Therefore, in server design, how to make the different power planes formed by 54V and 12V voltage inputs compatible is an urgent technical problem to be solved. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is how to make the different power planes formed by the input of 54V voltage and 12V voltage compatible in the prior art, thereby providing a compatible power module and server.

[0005] To achieve the above objectives, embodiments of the present invention provide a compatible power supply module, which includes:

[0006] The housing has a mounting cavity;

[0007] A first input power source is disposed in the housing, and the first input power source is used to supply power to a first load.

[0008] A step-down module is detachably installed in the mounting cavity; the input terminal of the step-down module is detachably connected to the first input power supply, and the output terminal of the step-down module is connected to the second load.

[0009] A second input power source is detachably installed in the mounting cavity; the second input power source is used to supply power to the second load.

[0010] When only the step-down module is installed in the mounting cavity, it is a single-power plane power supply mode.

[0011] When only the second input power supply is installed in the mounting cavity, it is a dual-power planar power supply mode.

[0012] Optionally, the step-down module has the same physical parameters as the second input power supply.

[0013] Optionally, the output interface of the step-down module is compatible with the output interface of the second input power supply.

[0014] Optionally, the output interface of the step-down module has the same parameters as the output interface of the second input power supply.

[0015] Optionally, the output interface of the step-down module has the same thickness and Pi n distribution of the gold fingers as the output interface of the second input power supply.

[0016] Optionally, the compatible power module also includes:

[0017] The system motherboard is housed within the casing; two step-down modules are located on either side of the system motherboard, and the current convergence point of the two step-down modules is located in the center of the system motherboard.

[0018] Optionally, the step-down module is provided with an anti-reverse mechanism, and the electrical components are assembled in the step-down module through the anti-reverse mechanism.

[0019] Optionally, the anti-reverse mechanism is a positioning post disposed in the step-down module, and the structural components inside the step-down module have positioning holes for the positioning post to be inserted.

[0020] Optionally, the step-down module is provided with a plug-in handle on its exterior.

[0021] The present invention also provides a server comprising: a first load, a second load, and a compatible power module as described in any of the preceding embodiments, wherein the first load is at least a GPU component, and the second load is at least a CPU, DIMM, HDD, or FANs component.

[0022] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0023] 1. This invention provides a compatible power supply module, comprising: a housing with a mounting cavity; a first input power supply disposed in the housing, the first input power supply being used to supply power to a first load; a step-down module detachably mounted in the mounting cavity; the input terminal of the step-down module being detachably connected to the first input power supply, and the output terminal of the step-down module being connected to a second load; and a second input power supply detachably mounted in the mounting cavity; the second input power supply being used to supply power to the second load; when only the step-down module is mounted in the mounting cavity, it is a single-power planar power supply mode; when only the second input power supply is mounted in the mounting cavity, it is a dual-power planar power supply mode.

[0024] This configuration allows for compatibility between different power planes formed by 54V and 12V input voltages. Users can also choose between single-power-plane or dual-power-plane power supply modes based on their specific needs, thus flexibly meeting the diverse requirements of different customers in various application scenarios.

[0025] 2. By setting the external parameters of the step-down module and the second input power supply to be the same, the step-down module and the second input power supply can be made completely compatible and perfectly matched in terms of physical form. Because the second input power supply is a PSU power supply, and the PSU power supply is a standard CRPS power module with standard physical dimensions, the step-down module needs to be designed to have the same appearance as the standard CRPS power supply. For example, the step-down module needs to be completely consistent with the CRPS power supply in terms of depth, width, and thickness, thereby improving the versatility of the step-down module.

[0026] 3. By making the output interface of the step-down module compatible with the output interface of the second input power supply, when the step-down module and the second input power supply are interchanged, they can be directly inserted into the interface inside the housing for use without the need for extra adapter cables or communication cables. This improves the overall versatility of the compatible power supply, thereby increasing the user's replacement efficiency and convenience.

[0027] 4. In this embodiment of the invention, by placing two step-down modules on opposite sides of the system motherboard and having the current convergence point of the two step-down modules located in the center of the system motherboard, the two step-down modules can share current, thereby improving the overall reliability of the power supply.

[0028] 5. By providing an anti-reverse mechanism inside the step-down module, this embodiment of the invention can prevent the internal components of the step-down module from being installed in reverse. At the same time, this anti-reverse mechanism also facilitates the rapid installation of the internal components of the step-down module, thereby improving production and assembly efficiency.

[0029] 6. In this embodiment of the invention, a plug-in handle is provided on the outside of the step-down module. When the user is using a dual-use power supply and needs to replace or install the step-down module, the user can easily hold the handle to easily plug and unplug the step-down module, thereby saving the user's physical strength and facilitating operation and maintenance.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] With the booming development of the AI ​​field and the increasing demand for computing power in various fields, GPUs have undergone multiple upgrades and replacements at a very rapid frequency. The power of GPUs has also been increasing with the continuous growth of computing power. As of the time of writing this patent, the power level of a single GPU chip has reached 700W and continues to evolve towards the 1000W power level.

[0042] The increasing power levels of GPUs have led to a continuous rise in current in traditional 12V power supply scenarios. The latest 700W / pcs GPU chips require approximately 60A of current. Such a large current causes significant voltage drop losses and heat generation in the PCB copper traces and cables, severely impacting the design of products such as servers. Therefore, in some high-power GPU applications, GPU-related power supplies have begun to experiment with 54V input voltage. Because the voltage is increased by 4.5 times, according to P=U*I, the current will become 1 / 4.5 of the original for the same power. Therefore, according to U=I*R, the voltage drop will also be reduced to 1 / 4.5 of the original. The resulting power loss and heat generation, according to P=U*U / R, will be reduced to 1 / 22.5 of the original, greatly reducing design complexity and losses, and also achieving benefits in areas such as energy saving and carbon neutrality.

[0043] However, in traditional design fields, such as CPUs, DIMMs, and HDDs, 12V voltage is still used as the input. In product design, these traditional components are far from being able to maturely use 54V voltage input. Therefore, for the foreseeable future, the coexistence of 12V and 54V input voltages will be the norm in GPU server systems. Thus, in server design, it is necessary to consider the influence between the two different power planes formed by the two voltage inputs.

[0044] In view of the above problems, it is necessary to consider a compatible power supply that can combine single-power-plane design and dual-power-plane design to meet the different needs of different customers in different application scenarios.

[0045] Example 1

[0046] like Figures 1 to 4 As shown, an embodiment of the present invention provides a compatible power module, which includes a housing, a first input power supply, a step-down module 1, and a second input power supply.

[0047] Specifically, in this embodiment of the invention, a mounting cavity is provided inside the housing, which can only accommodate one of the step-down module 1 and the second input power supply. The first input power supply is located in the housing and is used to supply power to the first load. The first input power supply can be a 54V PSU power supply 4. The step-down module 1 is detachably mounted in the mounting cavity, with its input terminal detachably connected to the first input power supply and its output terminal connected to the second load. When the step-down module 1 is mounted in the mounting cavity, the 54V PSU power supply 4 is stepped down before being input to the second load. The first load is a GPU component, and the second load is a CPU, DIMM, HDD, or FANs component. Furthermore, in this embodiment of the invention, the second input power supply is detachably mounted in the mounting cavity and is used to supply power to the second load.

[0048] In practical applications, when only the step-down module 1 is installed in the mounting cavity, it operates in a single-power-plane power supply mode. In principle, this mode is equivalent to a single-power-plane input design using a 54V PSU power supply 4. Figure 3 As shown, this is a single-supply planar design using 54V as the power input. The main input is 54V. After the power input passes through necessary protection circuits, it directly supplies the first load requiring 54V power, such as the GPU module. A branch of the 54V power supply, which is the main input, enters a 54V to 12V step-down module 1. This step-down module 1 converts the 54V power supply to 12V power output to supply the second load, such as the CPU, DIMM, HDD, FANs, etc.

[0049] When only the second input power supply is installed in the mounting cavity, it is a dual-power plane supply mode. In principle, this is equivalent to a dual-power plane design using both 54V and 12V PSU power supply inputs. Figure 4 As shown, the two power planes are separated from each other. The PSU power supply 4 is also divided into two types: a 54V power input directly supplies the first load that requires 54V power, such as the GPU module; and a 12V power input directly supplies the second load that requires 12V power, such as the CPU, DIMM, HDD, FANs and other modules.

[0050] This configuration allows for compatibility between different power planes formed by 54V and 12V input voltages. Users can also choose between single-power-plane or dual-power-plane power supply modes based on their specific needs, thus flexibly meeting the diverse requirements of different customers in various application scenarios.

[0051] Furthermore, in an optional embodiment of the present invention, the step-down module 1 has the same external dimensions as the second input power supply. For example, the step-down module 1 has a standard design with a depth of 185mm, a width of 40mm, and a thickness of 37.5mm, so that the step-down module 1 is completely consistent with the appearance of a standard CRPS power supply.

[0052] By setting the external parameters of the step-down module 1 and the second input power supply to be identical, this embodiment of the invention ensures that the step-down module 1 and the second input power supply are completely compatible and perfectly matched in terms of physical form. Since the second input power supply is a PSU power supply 4, and the PSU power supply 4 is a standard CRPS power module with standard physical dimensions, the step-down module 1 needs to be designed to have the same appearance as the standard CRPS power supply. For example, the step-down module 1 needs to be completely consistent with the CRPS power supply in the aforementioned depth, width, and thickness, thereby improving the versatility of the step-down module 1.

[0053] Of course, this embodiment is only an example of the external parameters of the step-down module 1, but it does not limit the scope of the embodiment. Those skilled in the art can change the external parameters of the step-down module 1 according to the actual situation, as long as the same technical effect can be achieved.

[0054] Furthermore, in an optional embodiment of the present invention, the output interface of the step-down module 1 is compatible with the output interface of the second input power supply. Specifically, the parameters of the output interface of the step-down module 1 and the output interface of the second input power supply are the same. The output interface of the step-down module 1 needs to be designed according to the shape of the gold fingers of the CRPS power supply, and the thickness and Pi n distribution of the gold fingers need to be strictly compatible with the CRPS power supply design. That is to say, the thickness and Pi n distribution of the gold fingers of the output interface of the step-down module 1 are designed to be the same as those of the output interface of the second input power supply.

[0055] This invention enables the output interface of the step-down module 1 to be compatible with the output interface of the second input power supply. When the step-down module 1 and the second input power supply are interchanged, they can be directly inserted into the interface inside the housing for use without the need for extra adapter cables or communication cables. This improves the overall versatility of the compatible power supply, thereby increasing the user's replacement efficiency and convenience.

[0056] In server systems, for reliability requirements, PSU power supplies 4 typically employ an N+N redundancy mechanism. This necessitates that the main power supply and backup power supply can achieve current sharing, meaning the two power supplies can distribute the load evenly, preventing one power supply from outputting excessive power while the other outputs insufficient power, which would negatively impact power supply lifespan. Therefore, when designing the mutually exclusive and compatible step-down modules 1 for PSU power supplies 4, current sharing between the two step-down modules 1 must also be considered. Thus, in an optional embodiment of this invention, the compatible power supply module further includes a system motherboard, which is housed within the casing. The two step-down modules 1 are located on opposite sides of the system motherboard, with the current convergence point of the two step-down modules 1 located at the center of the system motherboard.

[0057] In this embodiment of the invention, by placing two step-down modules 1 on opposite sides of the system motherboard and having the current convergence point of the two step-down modules 1 located in the center of the system motherboard, the two step-down modules 1 can share the current, thereby improving the overall reliability of the power supply.

[0058] Furthermore, in an optional embodiment of the present invention, the step-down module 1 and the PSU power supply 4 are mutually exclusive and compatible, which requires the step-down module 1 to also possess the easy-to-maintain characteristics of the PSU power supply 4 module. The step-down module 1 is internally provided with an anti-reverse mechanism 2, through which electrical components are assembled in the step-down module 1. Specifically, the anti-reverse mechanism 2 is a positioning post disposed in the step-down module 1, and the structural components inside the step-down module 1 have positioning holes at corner positions for the positioning post to be inserted.

[0059] In this embodiment of the invention, by setting an anti-reverse mechanism 2 inside the step-down module 1, the internal components of the step-down module 1 can be prevented from being installed in reverse. At the same time, the anti-reverse mechanism 2 also facilitates the rapid installation of the internal components of the step-down module 1, thereby improving production and assembly efficiency.

[0060] Furthermore, in an optional embodiment of the present invention, a plug-in handle 3 is provided on the outside of the step-down module 1. By providing a plug-in handle 3 on the outside of the step-down module 1, when a user is using a shared power supply and needs to replace or install the step-down module 1, the user can easily grasp the handle to easily plug and unplug the step-down module 1, thereby saving the user's physical effort and facilitating maintenance operations.

[0061] Of course, this embodiment is only an example of the plug-in handle 3 of the step-down module 1, but it does not limit it. Those skilled in the art can modify the relevant mechanisms that facilitate plugging and unplugging the step-down module 1 according to the actual situation, as long as the same technical effect can be achieved.

[0062] The present invention also provides a server comprising a first load, a second load, and a compatible power module as described in any of the preceding embodiments, wherein the first load is at least a GPU component, and the second load is at least a CPU, DIMM, HDD, or FANs component.

[0063] This configuration allows for compatibility between different power planes formed by 54V and 12V input voltages. Users can also choose between single-power-plane or dual-power-plane power supply modes based on their specific needs, thus flexibly meeting the diverse requirements of different customers in various application scenarios.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
