When the controller selects to call the first-level capacitor to supply power to the GPU (here, the target component is taken as an example of the GPU), the control switch Q1 is closed, and the control switches Q2 and Q3 are opened. Similarly, when the controller selects to call the second-level capacitor to supply power to the GPU, the control switch Q2 is closed, and the control switches Q1 and Q3 are opened. After the power supply is completed, the first controller can also detect the charging state of the capacitor in the corresponding level of energy storage unit through the signal collection resistor and the signal collector in the corresponding level of energy storage unit. The first controller collects the voltage change state of the signal collection resistor through the signal collector, thereby outputting a voltage signal for representing the discharge state of the capacitor. Then, the charging and discharging state of the corresponding capacitor is determined according to the voltage signal, and after the capacitor is in the discharging state, the first control switch in the corresponding level of energy storage unit is controlled to be in the closed state, and the first control switch in the energy storage unit of other levels is controlled to be in the open state, thereby controlling the power supply to charge the capacitor.

[0091] In the above application embodiments, in order to optimize the charging efficiency of the capacitor, the first controller can predict the power supply demand information of the to-be-powered component in a future time period according to the operation model information of the to-be-powered component between the current time, and then acquire the power supply state of the power supply to the server mainboard in a case where the power supply demand information represents that the to-be-powered component needs to use the target capacitor to be charged for power supply, and in a case where the power supply state represents that the power supply amount of the server power supply is less than the target power amount, the target capacitor in the target energy storage unit can be powered by other energy storage units in the multi-stage energy storage unit, so that the candidate energy storage unit for charging the target capacitor can be selected from other energy storage units according to the power demand amount of the target capacitor, and then the connection link between the target energy storage unit and the candidate energy storage unit is controlled to be closed by controlling the first control switch to be closed, so that the capacitor in the candidate energy storage unit can charge the target capacitor. Through the above content, the first controller predicts the power supply demand information of the to-be-powered component in the future by using the historical power supply demand information of the to-be-powered component, so as to detect the power supply state of the power supply after predicting that the to-be-powered component will be powered by the target capacitor to be charged, and then charge the target capacitor by other energy storage units in the multi-stage energy storage unit in a case where the power supply cannot charge the target capacitor at present, so as to avoid the influence of charging the target capacitor on the power supply of the server mainboard, and to charge the target capacitor to be used by other energy storage units, improve the timeliness of the energy storage of the target capacitor, and ensure the power supply efficiency of the target capacitor to the to-be-powered component.

[0092] Optionally, in the embodiments of the application, the controller can predict the power supply demand of the capacitor according to the operation mode information of the GPU. If the controller predicts that the first capacitor will need to power the to-be-powered component, but detects that the first capacitor is currently in a discharged state, and detects that there is no power surplus after the server power supply powers the server mainboard. At this time, the controller detects the discharge information of the second capacitor, and when it is detected that the second capacitor is currently in an undischarged state, the controller controls the second capacitor to charge the first capacitor, that is, controls the switches Q1 and Q2 to be closed and Q3 to be disconnected. At this time, the first capacitor and the second capacitor form a closed loop, that is, the second capacitor can charge the first capacitor.

[0093] Through the above configuration, when the controller detects that the capacitor is in the discharged state, on the one hand, the server power supply can be controlled to charge the capacitor in the presence of power surplus of the server power supply, and on the other hand, the capacitors can be controlled to charge each other in the absence of power surplus of the server power supply, so that the power supply efficiency of the capacitor to the to-be-powered component can be improved, and business waiting can be avoided.

For example, taking a graphics processor as the component to be powered, the graphics processor can have multiple state types under an overclocking model, and the peak power demand of the server is different under different state types.

FIG. 7 is a schematic diagram of a controller controlling the power supply of an energy storage unit according to an embodiment of the present application. As shown in FIG. 7, a multi-level energy storage unit structure is constructed by connecting a plurality of units in parallel, and energy storage units of different levels have different energy capacities. One end of the energy storage unit is connected to the charging port of the power supply, and the other end is connected to the power acquisition port of the component to be powered. The second controller is connected to each capacitor. Since the target component has different power requirements in the target running state, and the charging speed of the energy storage unit with different energy capacities is also different, the control logic of the energy storage unit for power supply to the target component can be set in the second controller, that is, the controller can select the energy storage unit with an energy capacity that meets the required residual power of the GPU (here, the target component is taken as an example) from the energy storage units with different energy capacities according to the running mode information of the GPU (that is, the residual power required by the GPU when the power supply cannot supply enough power to it), and charge the GPU.

[0110] Through the above configuration, by connecting a plurality of energy storage units with different energy capacities in parallel, a multi-level energy storage unit circuit structure is realized, and then by connecting the second controller to each level of energy storage unit, the power supply state of each level of energy storage unit to the target component can be controlled, and then the corresponding level of energy storage unit is selected according to the power supply requirements of the component to be powered, thereby improving the adaptability between the energy storage unit and the power requirements of the component to be powered, avoiding the problem that the charging time of the energy storage unit is poor when a high-level energy storage unit is used to supply power to a low-level power supply requirement component, thereby improving the power supply efficiency of the component.

[0111] As an optional embodiment, the energy storage unit includes a capacitor and a second control switch, the second control switch is connected to the second power supply link between the capacitor and the discharge port, and the second control switch is also connected to the second controller;

[0115] Through the above, by configuring the second control switch in the energy storage unit at each level, the power supply state of the corresponding level of the energy storage unit to the to-be-powered component is controlled by the controller controlling the on-off state of the second control switch, thereby improving the accuracy of control.

[0116] As an optional embodiment, the energy storage unit includes a capacitor and a second signal collector, wherein the second signal collector is connected to the second power supply link between the capacitor and the discharge port, and the second signal collector is also connected to the second controller.

[0117] The second signal collector is configured to collect discharge information of the capacitor and send the discharge information to the second controller.

[0118] The second controller is configured to, in a case where the discharge information indicates that the capacitor is in a discharged state, detect power supply information of the server mainboard from the power supply; and in a case where the power supply information indicates that the power demand of the server mainboard is less than the power supply of the power supply, control the power supply to charge the capacitor.

[0119] Optionally, in the embodiment of the present application, the second signal collector is configured to collect the voltage change on the capacitor link during the process of the capacitor, and the second signal collector can be, but is not limited to, a power amplifier, a voltage sensor, etc., and the present application does not limit this.

[0120] Optionally, in the embodiments of the present application, FIG. 8 is a schematic diagram of a controller controlling the power supply of an energy storage unit according to an embodiment of the present application. As shown in FIG. 8, each level of energy storage unit includes a capacitor (a first-level capacitor, a second-level capacitor, and a third-level capacitor in FIG. 8) and a second control switch (Q1, Q2, and Q3 in FIG. 8, which is a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) tube in the figure), the switch Q1, Q2, and Q3 is connected to the power supply link between the corresponding capacitor and the corresponding sub-discharge port deployed on the energy storage component configuration board, and the switch Q1, Q2, and Q3 is also connected to the second controller, which is configured to adjust the closed state of the switch Q1, Q2, and Q3. When the controller selects to call the first-level capacitor to supply power to the GPU (here, the target component is exemplified by the GPU), the control switch Q1 is closed, and the control switches Q2 and Q3 are opened. Similarly, when the controller selects to call the second-level capacitor to supply power to the GPU, the control switch Q2 is closed, and the control switches Q1 and Q3 are opened. After the power supply is completed, the second controller can also detect the charging state of the capacitor in the corresponding level of energy storage unit through the signal acquisition resistor and the signal acquisition device in the corresponding level of energy storage unit. The second control unit acquires the voltage change state of the signal acquisition resistor through the signal acquisition device, thereby outputting a voltage signal for representing the discharge state of the capacitor, and then determining the charge and discharge state of the corresponding capacitor according to the voltage signal. After the capacitor is in the discharge state, the second control switch in the corresponding level of energy storage unit is controlled to be in the closed state, and the second control switch in the energy storage unit of other levels is controlled to be in the open state, thereby controlling the power supply to charge the capacitor.

[0121] In the above application embodiments, in order to optimize the charging efficiency of the capacitor, the second controller can predict the power supply demand information of the to-be-powered component in a future time period according to the operation model information of the to-be-powered component between the current time, and then acquire the power supply state of the power supply to the server mainboard in a case where the power supply demand information represents that the to-be-powered component needs to use the target capacitor to be charged for power supply. In a case where the power supply state represents that the power supply amount of the server power supply is less than the target power amount, the target capacitor in the target energy storage unit can be powered by other energy storage units in the multi-stage energy storage unit, so that the candidate energy storage unit for charging the target capacitor can be selected from the other energy storage units according to the power demand amount of the target capacitor. Then, the connection link between the target energy storage unit and the candidate energy storage unit is controlled to be closed by controlling the second control switch to be closed, so that the capacitor in the candidate energy storage unit can charge the target capacitor. Through the above content, the second controller predicts the power supply demand information of the to-be-powered component in the future by using the historical power supply demand information of the to-be-powered component, so as to detect the power supply state of the power supply after predicting that the to-be-powered component will be powered by the target capacitor to be charged. In a case where the power supply cannot charge the target capacitor at present, the target capacitor is charged by other energy storage units in the multi-stage energy storage unit. In this way, on the one hand, the influence of charging the target capacitor on the power supply of the server mainboard can be avoided, and on the other hand, the target capacitor to be used can be charged by other energy storage units, so as to improve the timeliness of the energy storage of the target capacitor and ensure the power supply efficiency of the target capacitor to the to-be-powered component.

[0122] Optionally, in the embodiments of the present application, the controller can predict the power supply demand of the capacitor according to the operation mode information of the GPU. If the controller predicts that the first capacitor will need to power the to-be-powered component, but detects that the first capacitor is currently in a discharged state, and detects that there is no power surplus after the server power supply powers the server mainboard. At this time, the controller detects the discharge information of the second capacitor, and when it is detected that the second capacitor is currently in an undischarged state, the controller controls the second capacitor to charge the first capacitor, that is, controls the switches Q1 and Q2 to be closed and Q3 to be disconnected. At this time, the first capacitor and the second capacitor form a closed loop, that is, the second capacitor can charge the first capacitor.

[0123] Through the above configuration, when the controller detects that the capacitor is in the discharged state, on the one hand, the server power supply can be controlled to charge the capacitor when there is power surplus in the server power supply, and on the other hand, the capacitors can be controlled to charge each other when there is no power surplus in the server power supply, so that the power supply efficiency of the capacitor to the to-be-powered component can be improved, and business waiting can be avoided.

[0124] When the GPU (Graphics Processing Unit) in the server is overclocked, the peak load EDPp (Electric Design Peak Power) is 155% of the maximum load of the PSU (Power Supply Unit) for 200us, and the power supply support has doubts about triggering the OCP (Over Current Protection). The current protection (OCP) of the power supply is about 110% of the maximum load of the PSU for 1s, and the peak load capacity is about 140% for 100us. In order to meet the power supply demand of the overclocking peak load of the GPU in the server, additional capacitors can be added to support the peak load EDPp during overclocking in the following way: a capacitor board is designed to use large capacitors to support the peak load EDPp during overclocking. A super capacitor board composed of 30 1200u, 16v solid-state electrolytic capacitors is designed, and the capacitance is about = 1200uF*30 = 36000uF = 0.036F. The 12V power supply is first introduced into the capacitor board and then connected to the GPU to complete the support of the GPU EDPp function. Figure 9 is a schematic diagram of an optional capacitor board according to an embodiment of the present application. As shown in Figure 9, the capacitor board mainly plays a role in storing energy filtering for 4 GPU 12V power supply in the system, ensuring the normal power supply of the GPU under instantaneous heavy load. The capacitor board includes: a 12V input charging port, 4 12V discharge ports (as shown in the above figure: C0\C1\C2\C3), 30 1200uf, 16v solid-state aluminum electrolytic capacitors (only 16 are shown in the figure) to form a capacitor array. The connection relationship is: the capacitor board takes 12V power from the mainboard charging port through 4 2x4 power supply adapter lines, and after filtering and energy storage through the capacitor array, it is connected to the GPU0\GPU1\GPU2\GPU3 power supply interface through another 4 2x4 power supply adapter lines, realizing 4 GPU power supply.

[0125] The above method: additional capacitor boards are added to support the peak load EDPp during overclocking: this method does not affect the PSU design and does not affect the cost of the power supply. However, it is necessary to find a corresponding space in the system to arrange the capacitor board. Generally, a slot space corresponding to a PCIe function expansion card is found to arrange the capacitor board. However, this will occupy the slot space of the PCIe function expansion card, affect the system function expansion, cause limited configuration and insufficient system space, and thus affect market competitiveness.

[0126] To optimize the above problem, a super capacitor board (can support 4 12V GPUs) can be designed and directly combined with the PSU: use super capacitors 220mF / 4.2V in series 6 pieces = 220mF / 6 = 0.036F withstand voltage 25.2V. And match the balancing resistor 10K ohm / 0402*6 pieces. The super capacitor board card size is 100mm*28mm*1.6mm, the super capacitor board has a PSU input connector, and an output golden finger. The input connector accesses the PSU, and the output golden finger connector accesses the system motherboard. Figure 10 is an equivalent circuit diagram of an optional super capacitor board according to an embodiment of the application, as shown in Figure 10, the input connector (PSU conn input) of the super capacitor board (i.e. the charging port) accesses the PSU, and the output golden finger connector (i.e. the discharging port) accesses the system motherboard. The input connector and the output golden finger connector are connected through a connection link, a plurality of super capacitors (6 are shown in the figure, C in the figure is a super capacitor) and a plurality of balancing resistors (R in the figure is a balancing resistor) are connected in series and bridged between the connection link (one super capacitor is connected in parallel with one balancing resistor). Support instantaneous EDPp peak power capacitor value design:

[0127] It is expected to design a 1300W output 12.2V super capacitor that can support a new generation of GPUs 197% for 200uS. The required support peak current Ipeak calculation of 1300W EDPp curve is Ipeak = Pout / Vout*EDPp = 1300W / 12.2V*1.97 = 210A.

[0128] Capacitance value calculation:

[0129] The single instantaneous capacitor value design supports a rise from 5A to 210A for 200u Sec. The allowable voltage range is + / -7%. The voltage range that can be supported is 12.8V~11.6V.

[0130] Super capacitor calculation formula: = > 12.2V*(210A-5A)*200uF = 1 / 2*C*(12.8 2 -11.6 2 ), = > C = 34166uF = > optional 36000uF or 0.036F super capacitor.

[0131] Not more than the maximum value of the PSU capacitive load (1300W PSU Cap load Max is 50000uF).

[0132] Single board current analysis: super capacitor charge formula Q = I*t = C*dV,

[0133] Capacitor rated capacity; Q capacitance; dv: capacitor operating voltage difference; I: capacitor discharge current; t: capacitor discharge time; R: capacitor internal resistance.

[0134] Theoretical support current:

[0135] C: capacitance value V: capacitor voltage I = current during charging and discharging, dV actual voltage difference is 12.6V-11.4V, Q = C * dV = 0.036F * (12.6-11.4) = 0.0432 C = 0.0432A.s = 43.2mA.s.

[0136] The actual situation if need support 200us discharge current is: 0.0432A.s = 43.2mA.s = = > 43.2mA.s / 200us = 216A;

[0137] The actual situation if need support 1ms discharge current is: 0.0432A.s = 43.2mA.s = = > 43.2mA.s / 1ms = 43.2A;

[0138] The actual situation if need support 50ms discharge current is: 0.0432A.s = 43.2mA.s = = > 43.2mA.s / 50ms = 0.864A;

[0139] The actual situation if need support 20us discharge current is: 0.0432A.s = 43.2mA.s = = > 43.2mA.s / 20us = 2160A;

[0140] Through the above examples, it can be directly connected with the PSU and the host board to expand, without occupying the PCIe PCIe function expansion card slot space, affecting the system function expansion caused by limited configuration and system space shortage, thus affecting the market competitiveness. The design is simple, the stability is high, and the system layout space is not affected.

[0141] The specific examples in the embodiment can refer to the examples described in the above examples and exemplary embodiments, and the embodiment will not be repeated here.

[0142] It is apparent that those skilled in the art can modify and / or change the above-described modules or steps of the present application with general computing devices, which can be centralized on a single computing device or distributed on a network composed of multiple computing devices, which can be implemented by program codes executable by the computing devices, so that they can be stored in storage devices and executed by the computing devices, and in some cases, the steps shown or described can be executed in different orders, or they can be made into individual integrated circuit modules, or multiple modules or steps can be made into a single integrated circuit module. Thus, the present application is not limited to any specific combination of hardware and software.
