[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0017] It should be noted that in the description of the present application, the terms "comprising", "containing" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such a process, method, article or device. The terms "first", "second" and the like in the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence.

[0018] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0019] With the explosive development of artificial intelligence technology, the power supply demand for processors in servers is getting higher and higher. In the related art, the power input voltage is 48V, which is converted to 12V by a power conversion module, and then a multi-phase power supply scheme is used to convert 12V to 1.8V to supply power to the processor.

[0020] However, the conversion efficiency of this two-stage voltage conversion scheme is low and the conversion loss is large. Moreover, this scheme adopts a horizontal power supply architecture. Due to the long power supply distance of the horizontal power supply architecture, the transmission impedance is large. According to the formula P=I 2 R (P, I, R are power, current and impedance respectively), the current required by the processor is constant, so the large transmission impedance will result in large transmission loss.

[0021] The total power loss includes conversion loss and transmission loss. High loss will not only cause the temperature of the board in the server to rise and increase the cost of heat dissipation, but also cause energy waste and increase the customer's use cost.

[0022] To solve the above at least one technical problem, the present application provides a processor power supply system. The system connects the intermediate bus converter and the power supply sub-board with the power supply respectively, connects the intermediate bus converter with the voltage controller, connects the voltage controller with the power chip, connects the power chip with the mainboard, connects the transformer voltage regulator with the mainboard through the power supply sub-board, and sets the first bus on one side of the power supply sub-board. The power supply sub-board is connected with the power-in port of the transformer voltage regulator through the first bus, and the transformer voltage regulator and the power supply sub-board are arranged opposite to the processor. The voltage controller is in communication connection with the power chip, the transformer voltage regulator and the processor, which can realize the compatibility of one-stage conversion and two-stage conversion, and the one-stage conversion is a vertical power supply architecture, which can solve the problems of low conversion efficiency and large energy loss in the related art.

[0023] The processor power supply system of the present application embodiment will be described in detail below in combination with the drawings.

[0024] As shown in FIG. 1, the processor power supply system of the present application includes a power supply, an intermediate bus converter, a voltage controller, a power chip, a mainboard, a transformer voltage regulator and a processor. Figure 1As shown, the power supply system 100 of the processor of the embodiment of the present application comprises an intermediate bus converter 10, a voltage controller 20, a power chip 30, a transformer voltage regulator 40 and a power supply subboard 50.

[0025] The power input port of the intermediate bus converter 10 and the power input port of the power supply subboard 50 are respectively connected with a power supply, the power output port of the intermediate bus converter 10 is connected with the power input port of the voltage controller 20, the power output port of the voltage controller 20 is connected with the power input port of the power chip 30, and the power output port of the power chip 30 is connected with the mainboard through an inductor.

[0026] The transformer voltage regulator 40 is connected with the mainboard through the power supply subboard 50, wherein the transformer voltage regulator is arranged on one side of the power supply subboard, the other side of the power supply subboard is connected with the mainboard, the one side of the power supply subboard is provided with a first bus, the power supply subboard is connected with the power input port of the transformer voltage regulator through the first bus, and the transformer voltage regulator and the power supply subboard are arranged opposite to the processor. The processor is connected with the power output port of the transformer voltage regulator through vias arranged on the mainboard and the power supply subboard respectively. The voltage controller is in communication connection with the power chip, the transformer voltage regulator and the processor.

[0027] Specifically, taking the power voltage of 48V as an example, the power input port of the intermediate bus converter is connected with the power supply, and the 48V voltage can be converted into a 12V voltage. The power output port of the intermediate bus converter is connected with the power input port of the voltage controller, the power output port of the voltage controller is connected with the power input port of the power chip, and the power chip internally adopts a step-down architecture, which can convert the input high-voltage signal into a low-voltage signal required by the processor, such as converting the 12V voltage into a 1.8V voltage. The power output port of the power chip is connected with the mainboard through an inductor, which can supply the 1.8V voltage to the mainboard through the inductor. The mainboard distributes the 1.8V voltage to the processor for use, thereby realizing the power supply of the processor by using the 1.8V voltage. This voltage conversion mode is two-stage conversion, and the power supply architecture is horizontal power supply architecture. The intermediate bus converter, the voltage controller, the power chip and the inductor can be arranged on the mainboard.

[0028] The power chip is connected with the mainboard through the inductor, which is a power supply path. The electric energy can stabilize the current by using the electromagnetic induction characteristics in the switching mode of the power chip, and at the same time, the high-frequency noise can be suppressed, so that the secondary regulation and filtering of the intermediate voltage can be realized, and the high-precision and low-noise power can be provided for the mainboard, especially for the components on the mainboard which are sensitive to the power supply quality, such as the power supply of the processor.

[0029] The power supply sub-board is connected with the power supply, the transformer voltage regulator is connected with the main board through the power supply sub-board, one side of the power supply sub-board is provided with a first bus, the power supply sub-board is connected with the power input port of the transformer voltage regulator through the first bus, the transformer voltage regulator can directly convert 48V voltage into 1.8V voltage, and supply 1.8V voltage to the main board, and the main board distributes 1.8V voltage to the processor for use, so that the processor is powered by 1.8V voltage. The transformer voltage regulator is arranged on one side of the power supply sub-board, and the other side of the power supply sub-board is connected with the main board, wherein the one side of the power supply sub-board can be the top layer of the power supply sub-board, the other side of the power supply sub-board can be the bottom layer of the power supply sub-board, the other side of the power supply sub-board can be connected with the bottom layer of the main board, and the transformer voltage regulator and the power supply sub-board are arranged opposite to the processor. The processor is connected with the power output port of the transformer voltage regulator through the via holes arranged on the main board and the power supply sub-board. The voltage conversion mode is one-stage conversion, and the power supply architecture is vertical power supply architecture.

[0030] The transformer voltage regulator is an integrated power supply brick module, which is internally provided with a management chip, a capacitor, an inductor and a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) chip. The power supply sub-board is a small adapter board, and the functions thereof include physical adaptation, auxiliary filtering or protection, branch output, etc. The transformer voltage regulator is connected with the main board through the power supply sub-board, which is another power supply path and can be used to supply power to components on the main board that have special requirements for voltage levels and isolation, such as the processor, so as to meet the multi-element power supply demand of the main board. Meanwhile, as an adapter board, the power supply sub-board has high flexibility, and different processor power supply platforms can be flexibly adapted by replacing the power supply sub-board.

[0031] Figure 2 The figure is a comparison diagram of conversion efficiency curves of one-stage conversion and two-stage conversion for converting 48V voltage into 1.8V voltage. As shown in the figure, compared with the two-stage conversion scheme, the one-stage conversion scheme can improve the conversion efficiency by about 3%, thereby reducing the conversion loss. Moreover, the power supply architecture of one-stage conversion is vertical power supply architecture, the transformer voltage regulator and the power supply sub-board are arranged opposite to the processor, the processor is connected with the power output port of the transformer voltage regulator through the via holes arranged on the main board and the power supply sub-board, the current can flow vertically to the processor, the power supply distance is greatly shortened, and compared with the horizontal power supply architecture, the vertical power supply architecture can save at least 30% of transmission loss. Therefore, the one-stage conversion scheme using the vertical power supply architecture can improve the conversion efficiency and reduce the energy loss compared with the two-stage conversion using the horizontal power supply architecture.

[0032] Although the primary conversion scheme brings optimization in efficiency compared to the two-stage conversion scheme, the energy transmission speed of the primary conversion scheme is slower than that of the two-stage conversion scheme due to the presence of inductive devices such as transformers, and the response speed of the primary conversion scheme is slower than that of the two-stage conversion scheme.

[0033] Therefore, the voltage controller is communicatively connected with the power chip, the transformer voltage regulator and the processor respectively, the voltage controller can monitor the working voltage of the processor in real time, and output a driving signal and a pulse width modulation signal to control the working of the power chip and the transformer voltage regulator. Thus, the compatibility of the primary conversion and the two-stage conversion is realized. The dynamic response capability of the two-stage conversion and the high efficiency of the primary conversion are combined, the energy loss is reduced, and the dynamic response capability of the power supply is taken into account to ensure the stability of the supply voltage of the processor.

[0034] Thus, the embodiment connects the intermediate bus converter and the power supply sub-board with the power supply respectively, connects the intermediate bus converter with the voltage controller, connects the voltage controller with the power chip, connects the power chip with the mainboard, connects the transformer voltage regulator with the mainboard through the power supply sub-board, and sets a first bus on one side of the power supply sub-board, connects the power supply sub-board with the power-in port of the transformer voltage regulator through the first bus, and oppositely arranges the transformer voltage regulator and the power supply sub-board with the processor. The voltage controller is communicatively connected with the power chip, the transformer voltage regulator and the processor, the compatibility of the primary conversion and the two-stage conversion of the power supply is realized, and the primary conversion is the vertical power supply architecture, which can solve the problems of low conversion efficiency and large energy loss in the related art.

[0035] In some embodiments of the present application, one side of the power supply sub-board is further provided with a second bus and a plurality of first vias, and the plurality of first vias are distributed on one side of the power-out port of the transformer voltage regulator, wherein the power-out port of the transformer voltage regulator is connected with one end of the plurality of first vias through the second bus.

[0036] Specifically, Figure 3 As shown in the figure, the plurality of first vias are distributed on one side of the power-out port of the transformer voltage regulator, and the power-out port of the transformer voltage regulator is connected with one end of the plurality of first vias through the second bus. Figure 4 As shown in the figure, the power supply sub-board and the mainboard are connected with each other through the power supply sub-board and the mainboard, and the transformer voltage regulator converts the power supply voltage to output the power supply voltage to the plurality of first vias through the second bus, and the plurality of first vias continue to transmit the current upward, and finally realize the power supply to the processor.

[0037] The one side of the power supply sub-board of the embodiment is also provided with a second bus and a plurality of first vias. The plurality of first vias are distributed on one side of the power output port of the transformer voltage regulator. The power output port of the transformer voltage regulator is connected with one end of the plurality of first vias through the second bus. Thus, the current converted by the transformer voltage regulator is transmitted to the plurality of first vias through the second bus. The plurality of first vias further transmit the current to the processor. The plurality of first vias disperses the current load and improves the stability and safety of power supply.

[0038] In some embodiments of the present application, the other side of the power supply sub-board is provided with a plurality of second vias. One end of the plurality of second vias is connected with the other end of the plurality of first vias through the intermediate conductive layer of the power supply sub-board. The other end of the plurality of second vias is connected with the mainboard. The mainboard is provided with third vias. The third vias and the second vias correspond to each other. The other end of the second vias is connected with one end of the third vias. The other end of the third vias is connected with the processor.

[0039] Specifically, Figure 5 As shown in the schematic diagram of the plurality of second vias provided on the other side of the power supply sub-board, the other side of the power supply sub-board is provided with a plurality of second vias. One end of the plurality of second vias is connected with the other end of the plurality of first vias through the intermediate conductive layer of the power supply sub-board. The other end of the plurality of second vias is connected with the mainboard. The mainboard is provided with third vias. The third vias and the second vias correspond to each other. The other end of the second vias is connected with one end of the third vias. The other end of the third vias is connected with the processor. Thus, the electrical energy is transmitted to the processor. The intermediate conductive layer is a conductive circuit layer (usually made of metal such as copper) between the one side and the other side of the power supply sub-board. In the structure of the power supply sub-board, these conductive layers are separated by insulating materials and are mainly used to realize the electrical connection between different vias and lines.

[0040] The process between the power supply sub-board and the mainboard is a multi-level blind buried hole process. Multi-level blind buried hole refers to the combination of blind holes and buried holes with different depths and connection levels formed by multiple pressing, drilling and plating processes in a printed circuit board, realizing cross-layer accurate connection. The power supply via on the board is a conductive channel for connecting the power supply network between different conductive layers. Its core principle is to form a conductive path by drilling and plating copper on the hole wall to realize the transmission of power supply signals in multi-layer boards. When the power supply sub-board transmits electrical energy to the mainboard, the cross-layer direct connection of the multi-level blind buried hole reduces the length of the current transmission path, further reducing energy loss.

[0041] The power supply sub-board indirectly increases the number of vias through the multi-level blind buried hole process, which helps to reduce the transmission impedance. At the same time, the power supply sub-board also increases the heat dissipation area of the transformer voltage regulator, which helps to dissipate heat in the first conversion and ensures the power supply efficiency and stability.

[0042] The other side of the power supply sub-board of the embodiment is provided with a plurality of second through holes, one end of the plurality of second through holes is connected with the other end of the plurality of first through holes through the intermediate conductive layer of the power supply sub-board, and the other end of the plurality of second through holes is connected with the main board, thereby reducing energy loss in current transmission and ensuring that the main board can stably obtain efficient electric energy. The intermediate conductive layer is separated from other layers by an insulating material, which not only realizes electrical conduction function but also avoids the risk of short circuit between different lines. The multi-stage blind buried hole process forms a hole structure through multiple pressing and electroplating, which is more secure than traditional through-hole connection, can reduce the influence of environmental factors such as vibration and temperature change on the connection part, improve the long-term reliability of the connection between the power supply sub-board and the main board, and reduce the failure probability.

[0043] In some embodiments of the present application, the aperture of the first through hole is smaller than the aperture of the second through hole, and the setting density of the first through hole is greater than the setting density of the second through hole.

[0044] Specifically, since the power supply sub-board adopts a multi-stage blind buried hole process, before the inner layer is replaced, in order to minimize transmission impedance and optimize heat dissipation, the first through hole is generally punched according to 1A / via, and as many holes as possible are punched. After the inner layer is replaced, the second through hole remains consistent with the through hole position of the main board. Therefore, the setting density of the first through hole is greater than the setting density of the second through hole, but in order to ensure the transmission rate of electric energy, the aperture of the first through hole is smaller than the aperture of the second through hole, thereby achieving a balance between efficient electric energy transmission, optimized transmission impedance, and guaranteed heat dissipation performance.

[0045] The aperture of the first through hole of the embodiment is smaller than the aperture of the second through hole, and the setting density of the first through hole is greater than the setting density of the second through hole, thereby optimizing electric energy transmission efficiency, taking into account speed and stability, reducing transmission impedance, reducing energy loss, and ensuring heat dissipation performance.

[0046] In some embodiments of the present application, the transformer voltage regulator is a surface mount device, and the transformer voltage regulator is welded on one side of the power supply sub-board through a plurality of pads, wherein the plurality of pads include a first pad, a second pad, and a third pad, the first pad is located at the power inlet of the transformer voltage regulator, the second pad is located at the power outlet of the transformer voltage regulator, and the third pad is located at the grounding port of the transformer voltage regulator.

[0047] Specifically, the surface-mounted device is a mainstream component in electronic manufacturing to replace traditional plug-in components, and the core feature is that no hole needs to be drilled on the circuit board, and it is directly mounted on the surface of the printed circuit board and welded and fixed through reflow soldering process. The transformer voltage regulator is a surface-mounted device, which is welded on one side of the power supply sub-board through multiple pads, and the multiple pads include a first pad, a second pad and a third pad. The first pad is located at the power inlet of the transformer voltage regulator, and provides voltage before conversion for the transformer voltage regulator. The second pad is located at the power outlet of the transformer voltage regulator, and is the outlet for outputting converted voltage. The third pad is located at the grounding port of the transformer voltage regulator, and is used for connecting the ground wire of the power supply sub-board, and plays a role of current loop, electromagnetic interference shielding and voltage reference positioning, thereby ensuring stable operation of the transformer voltage regulator.

[0048] The transformer voltage regulator of the embodiment is a surface-mounted device, which simplifies the processing flow of the power supply sub-board, is beneficial to improving production efficiency, reducing the space occupation of the power supply sub-board, and facilitating the miniaturization design of equipment. The transformer voltage regulator is welded on one side of the power supply sub-board through multiple pads, including a first pad, a second pad and a third pad. The first pad is located at the power inlet of the transformer voltage regulator, the second pad is located at the power outlet of the transformer voltage regulator, and the third pad is located at the grounding port of the transformer voltage regulator. The first, second and third pads correspond to the power input, power output and grounding functions respectively, and have clear division of labor, thereby ensuring the clarity of the power transmission path during voltage conversion and the stability of voltage conversion.

[0049] In some embodiments of the present application, a solder ball is arranged at the port of the other end of each of the plurality of second vias, and the other side of the power supply sub-board is connected with the main board through the solder ball.

[0050] Specifically, a solder ball is arranged at the port of the other end of each of the plurality of second vias, and the other side of the power supply sub-board is connected with the main board through the solder ball, thereby transmitting electric energy. The power supply sub-board and the main board are both packaged with pads by BGA (Ball Grid Array) ball mounting process. The BGA ball mounting process is a connection technology for BGA packaged chips or circuit boards. The core is to weld tiny metal balls, usually tin balls, on the pads of the chip or circuit board, and these tin balls serve as the medium for electrical connection and mechanical fixation. The specific process generally includes: first, applying flux on the surface of the pad, then placing the tin ball on the corresponding pad through a template or a special device, and finally completing the ball mounting through reflow soldering. The advantage of this process is that it can achieve high-density electrical connection in limited space, which is suitable for scenarios that require a large number of pins, and the connection has high reliability.

[0051] Then the solder balls on the power supply sub-board are interconnected with the solder balls on the main board by surface mounting technology, combining the high-density connection ability of BGA ball planting process and the high-efficiency assembly advantage of surface mounting technology, which is suitable for realizing reliable connection of the main board and the power supply sub-board in a compact space, and gives consideration to connection performance and production efficiency.

[0052] The other end of each of the plurality of second vias in the embodiment is provided with a solder ball at a port, and the other side of the power supply sub-board is connected with the main board through the solder ball, thereby establishing a stable electrical path and ensuring efficient transmission of electric energy. With the help of BGA ball planting process, high-density electrical connection can be realized in limited space. In combination with the interconnection of surface mounting technology, the stability and anti-interference ability of the connection between the main board and the power supply sub-board are improved, batch production is facilitated, connection performance and production efficiency are taken into account, and large-scale manufacturing is suitable.

[0053] In some embodiments of the present application, the voltage controller monitors the working voltage of the processor in real time, and when the working voltage is within a preset voltage threshold range, the voltage controller controls the power chip to stop working; when the working voltage is not within the preset voltage threshold range, the voltage controller controls the power chip to start working.

[0054] Specifically, the transformer voltage regulator and the power chip are connected in parallel, the transformer voltage regulator is responsible for the first-stage conversion mode to supply power to the processor, and the power chip is responsible for the two-stage conversion mode to supply power to the processor, and the two are connected in parallel to form a design of double power supply paths in structure.

[0055] When the working voltage is within the preset voltage threshold range, the voltage controller controls the power chip to stop working, at this time, the transformer voltage regulator directly converts the power supply voltage into the voltage required by the processor, and supplies power to the processor through the main board, that is, the voltage conversion mode at this time is one-stage conversion.

[0056] When the working voltage is not within the preset voltage threshold range, the voltage controller controls the power chip to start working, at this time, the transformer voltage regulator directly converts the power supply voltage into the voltage required by the processor, and supplies power to the processor through the main board, and at the same time, the intermediate bus converter and the power chip also convert the power supply voltage into the voltage required by the processor, and supply power to the processor through the main board, that is, the voltage conversion mode at this time is two-stage conversion. At this time, the one-stage conversion circuit and the two-stage conversion circuit supply power to the processor at the same time, which can meet the power supply demand of the processor under different loads, reduce the power supply pressure of a single circuit, improve the power supply reliability, and optimize the dynamic response speed.

[0057] In addition, the preset voltage threshold range can be set by those skilled in the art according to actual conditions, which is not specifically limited here.

[0058] The embodiment realizes compatible power supply of one-stage conversion and two-stage conversion, improves conversion efficiency, reduces conversion loss, meets power supply requirements of different loads of the processor, reduces power supply pressure of a single circuit, improves power supply reliability, and optimizes dynamic response speed.

[0059] In some embodiments of the present application, the voltage controller monitors the working voltage of the processor in real time, including: the processor feeds back a voltage sensing signal to the voltage controller in real time through a voltage detection line; and the voltage controller analyzes the voltage sensing signal to obtain the working voltage.

[0060] Specifically, the processor internally integrates a voltage sensing unit (such as a voltage dividing resistor or a dedicated voltage sensor), which collects the actual working voltage of the core pin in real time and converts it into a transmittable voltage sensing signal. The signal is directly fed back to the voltage controller through a dedicated voltage detection line, which is a monitoring special line independent of the power supply main loop, avoiding the interference of power supply current fluctuation on the monitoring signal and ensuring the real-time and accuracy of the feedback.

[0061] After receiving the sensing signal, the voltage controller analyzes it through a built-in signal processing module (such as an analog-to-digital converter or a signal filtering unit). If the sensing signal is an analog signal, it is first converted into a digital signal by the analog-to-digital converter, and then the real working voltage value is calculated through a corresponding algorithm. If the sensing signal is a digital signal, it is directly decoded and verified to obtain the working voltage data, thereby monitoring the working voltage of the processor in real time.

[0062] Through the closed-loop link of voltage monitoring-analysis-regulation, the power supply voltage always matches the actual requirements of the processor, significantly improving the accuracy and stability of the power supply, and the energy efficiency ratio.

[0063] The processor of the embodiment feeds back a voltage sensing signal to the voltage controller in real time through a voltage detection line, and the voltage controller analyzes the voltage sensing signal to obtain the working voltage, thereby monitoring the working voltage of the processor in real time, providing a direct basis for subsequent power supply scheme switching, and also discovering voltage abnormalities in time to ensure the stability and reliability of the processor operation.

[0064] In some embodiments of the present application, the voltage controller is in communication connection with the intermediate bus converter, and the voltage controller is further configured to: control the intermediate bus converter to stop working when the working voltage is within a preset voltage threshold range; and control the intermediate bus converter to start working when the working voltage is not within the preset voltage threshold range.

[0065] Specifically, the voltage controller is connected with the intermediate bus converter, when the working voltage is in the preset voltage threshold range, the power supply voltage is directly converted into the voltage required by the processor by the transformer voltage regulator, the processor is powered through the mainboard, at this time, the voltage one-stage conversion mode is adopted, and the intermediate bus converter is a device used in the two-stage conversion mode, therefore, the voltage controller controls the intermediate bus converter to stop working. When the working voltage is not in the preset voltage threshold range, there are two voltage conversion modes at this time, namely, one-stage conversion and two-stage conversion compatibility, in the two-stage conversion, the voltage is converted once through the intermediate bus converter and then converted once through the power chip, therefore, the voltage controller controls the intermediate bus converter to start working.

[0066] The embodiment is connected with the intermediate bus converter through the voltage controller, when the working voltage is in the preset voltage threshold range, the voltage controller controls the intermediate bus converter to stop working, when the working voltage is not in the preset voltage threshold range, the voltage controller controls the intermediate bus converter to start working, so that the compatibility of the two-stage conversion mode and the one-stage conversion mode is realized, the conversion loss is further reduced, the conversion efficiency is improved, and the dynamic response ability of power supply is ensured.

[0071] Specifically, when the working voltage is not in the preset voltage threshold range, the voltage one-stage conversion compatible with two-stage conversion mode is adopted, when the processor load rises (for example, the processor enters the overclocking mode), the heat of the processor also rises, part of the heat of the processor is transferred to the mainboard and then to the power supply subboard, at this time, the heat dissipation device on the power supply subboard needs to be started to dissipate heat of the power supply subboard, therefore, the voltage controller controls the heat dissipation device to start, on the one hand, the temperature of the transformer voltage regulator on the power supply subboard can be reduced, on the other hand, the mainboard can be assisted to dissipate heat of the processor to ensure the working performance of the processor. When the working voltage is in the preset voltage threshold range, the voltage one-stage conversion mode is adopted, the voltage controller controls the heat dissipation device to be closed, thereby reducing the energy loss.

[0072] The voltage controller of the embodiment is also used for controlling the heat dissipation device to be started when the working voltage is not in the preset voltage threshold range, and controlling the heat dissipation device to be closed when the working voltage is in the preset voltage threshold range, thereby dissipating heat of the processor, avoiding damage caused by overheating, prolonging the service life of the processor, avoiding the circuit stability problem caused by heat accumulation of the mainboard, maintaining the continuous and efficient operation of the processor, controlling the heat dissipation device to be closed to reduce unnecessary energy loss, and overall realizing the on-demand heat dissipation and improving the overall energy efficiency ratio.

[0077] Specifically, the processor's power supply system also includes a first electronic fuse unit and a second electronic fuse unit. The function of the fuse units is power supply protection and isolation. The power input port of the intermediate bus converter is connected to the power supply through the first electronic fuse unit.

In the event of a fault, the first electronic fuse unit can automatically disconnect to protect the two-stage conversion circuit and also electrically isolate the circuits on the power supply side from those on the intermediate bus converter side. For example, when voltage fluctuations, surges, or other abnormalities occur at the power supply end, the first electronic fuse unit can block the transmission of abnormal signals to the intermediate bus converter and subsequent circuits, preventing power supply problems from affecting the downstream two-stage conversion circuits.

[0078] The first busbar is connected to the power input port of the transformer voltage regulator through the second electronic fuse unit. The power supply voltage can be transmitted to the transformer voltage regulator through the second electronic fuse unit, thereby realizing the protection and isolation of the first-stage conversion. In the event of a fault, the second electronic fuse unit can automatically disconnect to protect the circuit of the first-stage conversion. It can also electrically isolate the circuits on the power supply side from the circuits on the transformer voltage regulator side, so as to prevent voltage fluctuations, surges or other abnormalities on the power supply side from affecting the downstream first-stage conversion circuit.

[0079] The processor power supply system in this embodiment also includes a first electronic fuse unit and a second electronic fuse unit. The power input port of the intermediate bus converter is connected to the power supply through the first electronic fuse unit, and the first bus is connected to the power input port of the transformer voltage regulator through the second electronic fuse unit. This provides protection for the first-stage conversion circuit and the two-stage conversion circuit, strengthens electrical isolation, reduces the risk of fault propagation, and improves power supply stability.

[0080] In some embodiments of this application, a first electronic fuse unit is used to monitor the first current and voltage data at the output port of the first electronic fuse unit in real time, and control the first electronic fuse unit to disconnect when the first current and voltage data meets the first power-off condition; a second electronic fuse unit is used to monitor the second current and voltage data at the output port of the second electronic fuse unit in real time, and control the second electronic fuse unit to disconnect when the second current and voltage data meets the second power-off condition.

[0081] Specifically, the first electronic fuse unit collects the first current and voltage data of its own power output port in real time and continuously monitors and analyzes the data. When the monitored first current and voltage data meet the first power-off condition, the control mechanism will be automatically triggered to disconnect the first electronic fuse unit, thereby cutting off the power supply to the two-stage conversion circuit.

[0082] The second electronic fuse unit independently operates with the same working logic, acquires second current-voltage data of the power output port in real time and dynamically monitors the same, and automatically triggers a control mechanism to disconnect the second electronic fuse unit and cut off power supply of the first conversion loop once the second current-voltage data meets a second power-off condition. The two units independently monitor and trigger protection, respectively, and can provide precise overcurrent, overvoltage and other fault protection for the corresponding power circuit to ensure safe and stable operation of the related equipment and circuit system.

[0083] In addition, the first power-off condition and the second power-off condition can be set by those skilled in the art according to actual conditions, and are not specifically limited here.

[0084] The first electronic fuse unit of the embodiment is configured to monitor first current-voltage data of a power output port of the first electronic fuse unit in real time, and disconnect the first electronic fuse unit when the first current-voltage data meets a first power-off condition. The second electronic fuse unit is configured to monitor second current-voltage data of a power output port of the second electronic fuse unit in real time, and disconnect the second electronic fuse unit when the second current-voltage data meets a second power-off condition. Thus, precise and independent power supply protection is achieved, power supply safety is improved, and stable operation of the power supply system is ensured.

[0085] In some embodiments of the present application, the voltage controller is in communication connection with the first electronic fuse unit and the second electronic fuse unit, respectively. The voltage controller is further configured to receive a power-off signal sent by the first electronic fuse unit or the second electronic fuse unit, generate a processor frequency reduction signal according to the power-off signal, and send the processor frequency reduction signal to the processor, wherein the processor performs frequency reduction control according to the processor frequency reduction signal.

[0086] Specifically, the voltage controller is in communication connection with the first electronic fuse unit and the second electronic fuse unit, respectively, and undertakes the role of signal relay and control coordination. When the first electronic fuse unit or the second electronic fuse unit is disconnected due to monitoring that the current-voltage data of the power output port thereof meets a power-off condition, a power-off signal is sent to the voltage controller. After receiving the power-off signal, the voltage controller generates a processor frequency reduction signal and sends the signal to the processor. After receiving the frequency reduction signal, the processor performs frequency reduction control operation to reduce power consumption by reducing its own operating frequency, thereby reducing the demand for circuit power supply. In the case of partial loop power-off, the processor state is adjusted to adapt to the power supply change, thereby improving the stability and fault tolerance of the system as a whole, ensuring the minimum normal operation of the server and preventing data loss.

[0087] The embodiment is connected with the first electronic fuse unit and the second electronic fuse unit in communication through a voltage controller, used for receiving a power-off signal sent by the first electronic fuse unit or the second electronic fuse unit, generating a processor frequency reduction signal according to the power-off signal, and sending the processor frequency reduction signal to the processor, so that the processor performs frequency reduction control according to the processor frequency reduction signal, thereby improving the fault tolerance and stability of the power supply system, preventing data loss, ensuring the continuity of the server function, and further optimizing the dynamic adaptation of power consumption and power supply demand.

[0089] Specifically, for the first electronic fuse unit, in the process of monitoring the first current voltage data of the power output port in real time, if it is judged that the data does not satisfy the first power-off condition, i.e., the current voltage of the current circuit is in a safe and compliant range, the first electronic fuse unit will remain or control itself to be in a turned-on state, ensuring that the normal power supply to the corresponding circuit is not affected.

[0090] Similarly, when the second electronic fuse unit monitors the second current voltage data of the power output port in real time, if the monitoring result shows that the second current voltage data does not satisfy the second power-off condition, it means that the power parameters of the circuit meet the safe operation requirements, and at this time the second electronic fuse unit will control itself to maintain a turned-on state, ensuring the continuous and stable power supply to the application circuit. Both electronic fuse units follow the core logic of being turned on without failure, and remain the circuit unblocked under normal conditions, and only trigger the disconnection protection when a safety risk is detected, which not only realizes precise protection of the circuit, but also guarantees the power supply continuity under normal conditions.

[0091] The first electronic fuse unit of the embodiment is further configured to control the first electronic fuse unit to be turned on when the first current voltage data does not satisfy the first power-off condition, and the second electronic fuse unit is further configured to control the second electronic fuse unit to be turned on when the second current voltage data does not satisfy the second power-off condition, thereby guaranteeing the continuity of normal power supply and improving the reliability of the circuit.

[0092] Further, the voltage controller is further configured to receive an electronic fuse control signal sent by the processor, and control the first electronic fuse unit or the second electronic fuse unit to be disconnected or turned on according to the electronic fuse control signal, wherein the control priority of the voltage controller is higher than the control priority of the first electronic fuse unit and the second electronic fuse unit.

[0093] Specifically, the voltage controller also has more active control authority, which can receive the electronic fuse control signal sent by the processor and directly control the first electronic fuse unit or the second electronic fuse unit to be turned off or turned on according to the signal. The control priority of the voltage controller is higher than the control logic of the two electronic fuse units themselves, that is, even if the first or second electronic fuse unit makes a judgment to turn on or turn off based on its own monitoring data, as long as the voltage controller issues an opposite control instruction according to the processor signal, the instruction of the voltage controller will be the final one. The processor can realize global and active intervention of the two electronic fuse units through the voltage controller, and can flexibly control the on-off of the loop according to the overall operation demand of the system, such as load adjustment, mode switching, etc., while ensuring the local protection function, and improves the control flexibility and cooperativity of the overall power supply system.

[0094] As a possible case, the processor can also receive a user instruction, generate the above-mentioned electronic fuse control signal according to the user instruction, to control the first electronic fuse unit or the second electronic fuse unit to be turned off or turned on, so as to realize the continuous power supply of the processor during the maintenance process of the power supply system.

[0095] The voltage controller of the embodiment is also used to receive the electronic fuse control signal sent by the processor, and control the first electronic fuse unit or the second electronic fuse unit to be turned off or turned on according to the electronic fuse control signal. The control priority of the voltage controller is higher than that of the first electronic fuse unit and the second electronic fuse unit, so as to realize the system-level global control, avoid the limitation of local judgment, improve the flexibility and cooperativity of the power supply system, and adapt to multiple scene requirements.

Meanwhile, the alarm module is in communication connection with the voltage controller to form a complete alarm control link. When the first electronic fuse unit or the second electronic fuse unit triggers disconnection and sends a power-off signal to the voltage controller, the voltage controller generates corresponding alarm information based on the power-off signal in addition to the processor frequency reduction signal, and controls the alarm module according to the alarm information, for example, triggers the alarm module to send a sound, light or other form of warning signal. When the power supply system has a loop power-off fault, the alarm module can timely feedback the abnormal state to the outside world, so that the operator can quickly detect the problem and perform troubleshooting, and the fault response capability and maintainability of the system are further improved.
