DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0021] Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0022] In the digital age, servers play a core role in information processing and transmission, and their stability is crucial to business continuity. The server power supply structure is the key infrastructure to ensure its continued reliable operation.

[0023] With the rapid development of information technology, servers are taking on more and more tasks, placing increasing demands on power supply architectures. Traditional server power supply architectures typically rely on a single power input. A power failure can cause server downtime, resulting in data loss and business interruption. To address this issue, modern server power supply architectures are gradually evolving to include multiple power inputs and redundant designs.

[0024] At present, the schematic diagram of the existing server power supply structure can be found in Figure 1 , Figure 1 A schematic diagram of the existing server power supply structure provided in an embodiment of the present application.

[0025] like Figure 1 As shown, the existing server power supply structure uses two three-phase 380V AC (Volts Alternating Current, abbreviated as VAC) power supplies, namely power supply A and power supply B. It should be noted that a wire in the power distribution module (PDM) represents the line (live), neutral, and ground wires for AC voltage input or the positive, negative, and ground wires for DC voltage input.

[0026] At the beginning of power supply line A, a power distribution module is installed. Its function is to initially distribute the incoming power and distribute it to different branch circuits. The power is then connected to the power shelf, which provides mounting support and physical space for multiple power supply units (PSUs), such as PSU1 and PSU2, allowing for neat and orderly installation of power supply equipment.

[0027] At the same time, power supply line A also includes devices that combine an automatic transfer switch (ATS) and a PSU, such as ATS+PSU1 and ATS+PSU2.

[0028] When power supply line A fails, ATS can quickly detect the problem and automatically switch to the backup power supply to ensure that the server will not stop running due to the failure of a single power supply line.

[0029] The structure of power supply path B is similar to that of path A, consisting of the ATS + PSU3. Under normal circumstances, both paths provide stable power to the server. If a problem occurs in one path, the other path immediately takes over, ensuring uninterrupted server operation. This dual-path and redundant design significantly improves server power reliability, reducing downtime and data loss caused by power failures.

[0030] Furthermore, this server power supply structure has the following advantages:

[0031] Mature technology: The technology used has been verified by the market, with high stability, low failure rate and relatively easy maintenance;

[0032] Low hidden dangers: Due to the mature technology used, there is less uncertainty during the implementation of the plan, and the hidden dangers are relatively low;

[0033] Easy to integrate: Mature technologies generally have good compatibility, facilitating system integration and expansion.

[0034] However, unnecessary redundancy or poor coordination between different devices in this server power supply structure results in low overall power supply efficiency.

[0035] Furthermore, the existing server power supply structure requires a large number of devices, which means higher initial investment costs and long-term maintenance costs. Furthermore, this server power supply structure is already fixed, and as server power increases, the existing power supply solution cannot meet server needs.

[0036] In response to the above problems, this application proposes a server power supply structure. By integrating a power switching switch, a power distribution module, and wires connecting the power switching switch and the power distribution module into the distribution module, the server power supply structure design is made more compact and efficient, reducing unnecessary components and energy consumption, thereby improving the overall power supply efficiency of the server.

[0037] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0038] Figure 2 The present invention provides a schematic diagram of a server power supply structure. Figure 2 As shown, the server power supply structure provided in the embodiment of the present application is a heterogeneous server power supply structure, which includes a distribution module and a power conversion module. The distribution module integrates a power switching switch, a power distribution module, and a wire connecting the power switching switch and the power distribution module. The input end of the power distribution module is connected to the power supply, the power distribution module is connected to one end of the power switching switch, and the other end of the power switching switch is the output end of the distribution module.

[0039] In this embodiment, it will be appreciated that the input port of the power distribution module is directly connected to the power source. This connection enables the power distribution module to receive power. Through this connection, the power distribution module can draw power from the power source and distribute it to different devices or circuits to meet various power needs. This configuration is the foundation of the power distribution system, ensuring that power is efficiently transmitted and managed to support the normal operation of the equipment.

[0040] Furthermore, the other end of the power distribution module is connected to a power switch, which is used to switch between different power sources to ensure that the server can receive continuous power. Through this connection, the power distribution module can switch between different power sources, ensuring that the server has a stable power supply in different situations.

[0041] The embodiment of the present application integrates the power switching switch, the power distribution module, and the wires connecting the power switching switch and the power distribution module into one device, thereby reducing the length of the power transmission path and reducing transmission losses, thereby achieving the effect of improving the overall power supply efficiency.

[0042] Based on the above embodiment, the distribution module outputs power through the C19 interface. The distribution module is a key component in the entire server power supply structure. It receives power input from different power sources and distributes the input power to different devices or circuits based on demand. The distribution module then outputs power through the C19 interface.

[0043] The C19 interface is a power output interface. Specifically, it is a C19 socket specified in the IEC 60320 standard. The C19 interface consists of a rectangular shape and three jacks for the phase, neutral, and ground wires. The standardized design of the C19 interface facilitates subsequent connection and replacement, thereby improving the maintainability of the server power supply structure.

[0044] Furthermore, each C19 interface supports dual input of four combinations of one DC voltage or AC voltage and one DC voltage or AC voltage.

[0045] In the embodiment of the present application, the distribution module is output through a universal C19 interface to reduce the cost of the server power supply structure.

[0046] Furthermore, the C19 interface corresponds to the power switch one by one. This means that each C19 interface is controlled by a corresponding power switch. For example, the first C19 interface is controlled by the first power switch corresponding to it.

[0047] Furthermore, the number of C19 interfaces is the same as the number of power switches. For example, if the number of power switches is 3, the number of C19 interfaces is also 3.

[0048] The embodiment of the present application achieves precise control of each C19 interface connected device or circuit through a one-to-one correspondence between the power switching switch and the C19 interface.

[0049] Based on the above embodiment, the C19 interface and the power conversion module are connected via a power line converted by the interface.

[0050] In this embodiment, it can be understood that the C19 interface is connected to the power conversion module through the power cord of the interface adapter, wherein the function of the power conversion module is to adjust or convert the parameters of the received power to realize power supply to the server, such as changing the voltage and current to realize power supply to the server.

[0051] Furthermore, the power cord of the interface adapter is used to transmit power and is connected through an interface conversion method. This interface conversion method can solve the compatibility problem between interface standards and ensure smooth power transmission.

[0052] Furthermore, since the input port of the power conversion module is a C20 interface, the power cable of the interface conversion is a C19 interface to C20 interface power cable. This means that the C19 interface is connected to the power conversion module via a C19 interface to C20 interface power cable.

[0053] In the embodiment of the present application, the cost of the server power supply structure is reduced by connecting the C19 interface to the power conversion module through a power cable that converts the C19 interface to the C20 interface.

[0054] Based on the above embodiment, the distribution module is connected to two power supply lines that provide backup for each other. In this embodiment, it can be understood that if one power supply line fails or is interrupted, the other power supply line can immediately take over, thus ensuring continuous power supply to the server. This dual-power supply connection for backup greatly improves the reliability and stability of the system.

[0055] Furthermore, the distribution module is connected to two power supply lines that back up each other, and intelligently switches the power input according to different situations, thereby reasonably distributing the input power and ensuring the overall power supply efficiency of the server.

[0056] Furthermore, each of the two power supplies uses a standard Common Redundant Power Supply (CRPS). Furthermore, each of the two power supplies has the following conditions:

[0057] Each power supply provides three-phase AC voltage;

[0058] Each power supply provides three-phase DC voltage;

[0059] Each power supply provides three-phase AC voltage and three-phase DC voltage.

[0060] In the first case, it can be assumed that each power supply provides a three-phase AC voltage. For example, power supply A provides a three-phase 380V AC voltage, and power supply B provides a three-phase 380V AC voltage. The embodiments of the present application provide mutually backed-up AC power supplies to share the load of each power supply, avoid overloading a single power supply path, reduce voltage fluctuations caused by overload, and thus improve the overall power supply efficiency of the server.

[0061] In the second scenario, it is understood that each power supply provides a three-phase DC voltage. For example, power supply A provides a three-phase 270V DC voltage, and power supply B provides a three-phase 270V DC voltage. This embodiment of the present application further ensures output voltage stability by providing mutually backed-up DC power supplies, thereby providing a reliable power supply for the server.

[0062] In the third case, it can be understood that each power supply provides three-phase DC voltage and three-phase AC voltage. For example, power supply A provides three-phase 270V DC voltage and three-phase 380V AC voltage, and power supply B provides three-phase 270V DC voltage and three-phase 380V AC voltage. By providing AC power supply and DC power supply that back up each other, the embodiment of the present application can quickly start the backup power supply of another voltage type when a power supply of one voltage type fails, thereby ensuring that the server can receive continuous power supply. For example, if there is a problem with the DC power supply, the AC backup power supply can take over immediately, and vice versa. This double protection greatly improves the reliability of the server power supply structure and reduces the hidden dangers of server power interruption due to power failure.

[0063] The following examples illustrate the server power supply structure provided by the embodiment of the present application. In the server power supply structure provided by the embodiment of the present application, the power switch, the power distribution module, and the wires connecting the power switch and the power distribution module are integrated into the distribution module.

[0064] Furthermore, the distribution module is connected to two power supply lines that serve as backup for each other. Each of the two power supply lines has the following conditions: each power supply line provides a three-phase AC voltage; each power supply line provides a three-phase DC voltage; each power supply line provides a three-phase AC voltage and a three-phase DC voltage.

[0065] In the first scenario, each power supply can be assumed to provide three-phase AC voltage. For example, the first power supply provides three-phase 380V AC voltage, and the second power supply provides three-phase 380V AC voltage. By providing mutual backup AC power, the load of each power supply is shared, avoiding overloading of a single power supply path and reducing voltage fluctuations caused by overload, thereby improving the overall power supply efficiency of the server.

[0066] In the second scenario, each power supply provides three-phase DC voltage. For example, the first power supply provides three-phase 270V DC voltage, and the second power supply provides three-phase 270V DC voltage. By providing mutual backup DC power supply, the stability of the output voltage is further ensured, providing a reliable power supply for the server.

[0067] In the third case, it can be understood that each power supply provides three-phase DC voltage and three-phase AC voltage. For example, the first power supply provides three-phase 270V DC voltage and three-phase 380V AC voltage, and the second power supply provides three-phase 270V DC voltage and three-phase 380V AC voltage. By providing AC power and DC power supplies that backup each other, when one voltage type of power supply fails, the backup power supply of the other voltage type can be quickly activated to ensure that the server can receive continuous power supply. For example, if the DC power supply has a problem, the AC backup power supply can immediately take over, and vice versa. This dual protection greatly improves the reliability of the server power supply structure and reduces the hidden dangers of server power outages due to power failures.

[0068] Furthermore, the input end of the power distribution module is connected to the power supply, which is then connected to one end of the power switch. The other end of the power switch is the output end of the distribution module, and the distribution module outputs power through the C19 interface. The C19 interface is a power output interface. Specifically, the C19 interface is a C19 socket in the IEC 60320 standard. The C19 interface includes a rectangular shape and three jacks, one for the phase line, the other for the neutral line, and the ground line. The standardized design of the C19 interface facilitates subsequent connection and replacement, thereby improving the maintainability of the server power supply structure.

[0069] In order to power the server, it is necessary to connect the distribution module to the power conversion module, and the distribution module and the power conversion module are connected through a power cord that is converted via an interface. Since the distribution module outputs through the C19 interface, a power cord that converts the C19 interface to the C20 interface is selected to connect the distribution module to the power conversion module. Among them, the function of the power conversion module is to adjust or convert the parameters of the received power to power the server, such as changing the voltage and current to power the server. Furthermore, the power cord converted by the interface is used to transmit power and is connected through an interface conversion method. This interface conversion method can solve the compatibility issues between interface standards and ensure the smooth transmission of power.
