[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0045] In this embodiment, a server power supply device is provided. Figure 1 A schematic diagram of a server power supply device according to an embodiment of the present application Figure 1 ,like Figure 1 As shown, the device includes:

[0056] Optionally, in an embodiment of the present application, the energy storage component configuration board is a component outside the connection link between the power supply and the power input port on the server mainboard. The energy storage component configuration board is used to configure the energy storage component, so as to connect the energy storage component to a power receiving port of a specific component to be powered on the server mainboard (the power receiving port is a connection port extended on the server mainboard for the component to be powered, and the component to be powered can be directly powered through the connection port), thereby realizing targeted power supply to the component to be powered by means of an external energy storage component, that is, the connection relationship between the sub-discharge port on the energy storage component configuration board and the power receiving port of the component to be powered on the server mainboard can be adjusted according to the power supply demand of the component to be powered on the server mainboard.

[0060] Optionally, in an embodiment of the present application, the energy storage component may be, but is not limited to, an energy storage component formed by connecting a plurality of energy storage units in series. During use, the storage amount of the energy storage component may be adjusted by adjusting the number of energy storage units connected in series and the energy storage parameters of the energy storage units connected in series.

[0061] Through the above configuration, by configuring a charging port and a plurality of sub-discharging ports on the energy storage component configuration board, the second end of each energy storage device is connected to the corresponding sub-discharging port, and then according to the operation requirements of the component to be powered, the sub-discharging port is connected to the power receiving port of the component to be powered with the target operation state requirements on the server mainboard, so as to provide targeted power supply to the equipment to be powered with the peak power supply demand, thereby improving the power supply efficiency of the component to be powered.

[0062] As an optional embodiment, the energy storage component includes a plurality of energy storage units, and the plurality of energy storage units are connected in series in sequence.

[0063] Optionally, in an embodiment of the present application, the energy storage unit is a component used by the energy storage component during operation. The energy storage unit may include but is not limited to capacitors (solid-state electrolytic capacitors or supercapacitors), energy storage batteries, etc., and this solution does not limit this.

[0064] Through the above content, multiple energy storage units are connected in series to increase the electric energy capacity of the energy storage component, and the electric energy capacity of the energy storage component can be quickly adjusted by adjusting the number of energy storage units connected in series.

[0065] As an optional embodiment, the energy storage unit includes a solid electrolytic capacitor.

[0066] Optionally, in an embodiment of the present application, a solid-state electrolytic capacitor is a capacitor based on a solid electrolyte, which has the characteristics of high reliability, long life, low equivalent series resistance, and strong stability. The solid-state electrolytic capacitor can be, but is not limited to, an organic semiconductor aluminum electrolytic capacitor, a polymer conductor aluminum electrolytic capacitor, etc., and can also be a supercapacitor plate composed of solid electrolyte, which is not limited in this solution.

[0067] As an optional embodiment, the energy storage unit includes a super capacitor and a balancing resistor, and the super capacitor and the balancing resistor are connected in parallel.

[0068] As an optional embodiment, the energy storage component includes a plurality of energy storage units and a first controller, the plurality of energy storage units have different electrical energy capacities, the plurality of energy storage units are connected in parallel, and the first controller is connected to each of the energy storage units.

[0069] The first controller is used to control a target energy storage unit among the plurality of energy storage units, whose state type matches the target operating state, to be in a state of supplying power to the target component.

[0070] Optionally, in an embodiment of the present application, the first controller is used to select an energy storage unit that can supply the remaining power required by the target component from a plurality of energy storage units with different power capacities to power the target component according to the remaining power required by the target component when the power supply is insufficient. The first controller can be but is not limited to a CPU, an MCU (MicroController Unit), a DSP (Digital Signal Processor), etc., and this solution does not limit this.

[0071] Optionally, in an embodiment of the present application, the peak power demand of the component to be powered is different under different state types of the target operating state. For example, taking the component to be powered as a graphics processor as an example, the graphics processor may have multiple state types under the overclocking model operation, and the peak power demand of the server is different under different state types. For example, the peak power demand under the first state type is 110% of the total power of the power supply, the peak power demand under the second state type is 130% of the total power of the power supply, and the peak power demand under the third state type is 150% of the total power of the power supply.

[0072] Optionally, in the embodiment of the present application, in order to meet the power supply requirements of the components to be powered on the server mainboard under target operating states of different state types, a plurality of energy storage units connected in parallel can be configured. The electric energy capacity of different energy storage units is different. Therefore, by controlling the energy storage units connected to the components to be powered, it is possible to select a suitable energy storage unit for power supply according to the power supply requirements of the components to be powered, thereby improving the power supply efficiency of the energy storage unit to the power supply components. Figure 3 A schematic diagram of a controller controlling power supply of an energy storage unit according to an embodiment of the present application Figure 1 ,like Figure 3 As shown, a multi-level energy storage unit structure is constructed by connecting multiple units in parallel. 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 receiving port of the component to be powered. The first controller is connected to each capacitor. Since the target component has different demands for electric energy under the target operating state, and the charging speeds of energy storage units with different energy capacities are also different, the control logic for controlling the energy storage unit to power the target component can be set in the first controller. That is, the controller can select an energy storage unit with an energy capacity that meets the remaining energy required to supply the GPU from among the energy storage units with different energy capacities to charge the GPU according to the operating mode information of the GPU (here the target component is the GPU as an example) (that is, the remaining energy required by the GPU when the power supply is insufficient).

[0073] Through the above configuration, by connecting multiple energy storage units with different electric energy capacities in parallel, a circuit structure of a multi-level energy storage unit is realized, and then by connecting the first controller to the energy storage unit of each level, the power supply state of the energy storage unit of each level to the target component can be controlled, and then the energy storage unit of the corresponding level is selected to power the component to be powered according to the power supply demand of the component to be powered, thereby improving the adaptability between the energy storage unit and the power demand of the component to be powered, avoiding the problem of poor charging time of the energy storage device after using a high-level energy storage unit to power a component with a low-level power supply demand, thereby improving the power supply efficiency to the component.

[0074] As an optional embodiment, the energy storage unit includes a capacitor and a first control switch, the first control switch is connected to a first power supply link between the capacitor and the sub-discharge port, and the first control switch is also connected to the first controller;

[0075] The first controller is used to adjust the closed state of the first control switch;

[0076] The first control switch is used to adjust the on / off state of the first power supply link.

[0077] Optionally, in an embodiment of the present application, the first control switch is a component used to adjust the on / off state of the power supply link. The first control switch may be, but is not limited to, an electronic switch, a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), etc. This solution does not limit this.

[0078] Through the above content, by configuring the first control switch in each level of energy storage unit, the controller controls the on-off state of the first control switch to control the power supply state of the energy storage unit of the corresponding level to the power supply component, thereby improving the accuracy of control.

[0079] As an optional embodiment, the energy storage unit includes a capacitor and a first signal collector, wherein the first signal collector is connected to a first power supply link between the capacitor and the sub-discharge port, and the first signal collector is also connected to the first controller;

[0080] The first signal collector is used to collect discharge information of the capacitor and send the discharge information to the first controller;

[0081] The first controller is used to detect the power supply information of the power supply to the server mainboard when it is determined that the discharge information indicates that the capacitor is in a discharged state; and control the power supply to charge the capacitor when the power supply information is used to indicate that the power demand of the server mainboard is less than the power supply of the power supply.

[0082] Optionally, in an embodiment of the present application, the first signal collector is used to collect voltage changes on the capacitor link during the capacitor indication process. The first signal collector can be but is not limited to a power amplifier, a voltage sensor, etc., and this solution does not limit this.

[0083] Optionally, in the embodiment of the present application, Figure 4 A schematic diagram of a controller controlling power supply of an energy storage unit according to an embodiment of the present application Figure 2 ,like Figure 4 As shown, each energy storage unit includes a capacitor ( Figure 4 The first capacitor, the second capacitor, the third capacitor) and the first control switch ( Figure 4Q1, Q2, Q3 in the figure, the control switch is MOS (Metal-Oxide-Semiconductor Field-Effect Transistor), the switches Q1, Q2, Q3 are connected to the power supply link between the corresponding capacitor and the corresponding sub-discharge port deployed on the energy storage component configuration board, the switches Q1, Q2, Q3 are also connected to the first controller, the first controller is used to adjust the closing state of the switches Q1, Q2, Q3, when the controller chooses to call the first-level capacitor to power the GPU (here the target component is GPU as an example), the control switch Q1 is closed, and the control switches Q2 and Q3 are disconnected. Similarly, when the controller chooses to call the second-level capacitor to power the GPU, the control switch Q2 is closed, and the control switches Q1 and Q3 are disconnected. After the power supply is completed, the first controller can also detect the charging state of the capacitor in the energy storage unit of the corresponding level through the signal acquisition resistor and the signal collector in the energy storage unit of the corresponding level. The first controller collects the voltage change state at both ends of the signal acquisition resistor through the signal collector, thereby outputting a voltage signal for characterizing the discharge state of the capacitor, and then determines the charging and discharging state of the corresponding capacitor according to the voltage signal. After the capacitor is in the discharge state, the first control switch in the charging unit of the corresponding level is controlled to be in a closed state, and the first control switches in the energy storage units of other levels are controlled to be in an open state, thereby controlling the power supply to charge the capacitor.

[0084] In the above-mentioned application embodiment, in order to optimize the charging efficiency of the capacitor, when the first controller detects that the capacitor needs to be charged, it can predict the power supply demand information of the component to be powered in a future time period based on the operation model information of the component to be powered between the current time and the current power supply status of the power supply to the server motherboard is obtained when the power supply demand information indicates that the component to be powered needs to be powered by the target capacitor to be charged. When the power supply status indicates that the remaining power supply of the server power supply is less than the target power, the target capacitor in the target energy storage unit can be powered by other energy storage units other than the target energy storage unit in the multi-level energy storage unit. Therefore, candidate energy storage devices for charging the target capacitor can be screened out from other energy storage units according to the power demand of the target capacitor, and then the target energy storage unit and the first energy storage unit in the candidate energy storage unit are controlled. The switch is controlled to close in such a way as to control the closing of the connection link between the target energy storage unit and the candidate energy storage unit, so that the capacitor in the candidate energy storage device can charge the target capacitor. Through the above content, the first controller uses the historical power supply demand information of the component to be powered to predict the future power supply demand information of the component to be powered, so that after predicting that the target capacitor to be charged will be used to power the component to be powered, the power supply status of the power supply is detected, and then when the power supply is currently unable to charge the target capacitor, the target capacitor is charged through other energy storage units in the multi-level energy storage unit. On the one hand, the impact of charging the target capacitor on the power supply of the server motherboard can be avoided, and on the other hand, the target capacitor to be used can be charged through other energy storage units, thereby improving the timeliness of energy storage of the target capacitor and ensuring the power supply efficiency of the target capacitor to the component to be powered.

At this time, the first capacitor and the second capacitor form a closed loop, and the second capacitor can be controlled to charge the first capacitor.

[0086] Through the above configuration, when the controller detects that the capacitor is in a discharged state, on the one hand, it can control the server power supply to charge the capacitor when there is surplus power in the server power supply.

The further energy storage device includes an adapter board and an energy transmission component, and a connection link connecting the charging port and the discharging port is configured on the adapter board.

Furthermore, the second slot may be, but is not limited to, include a plurality of second sub-slots connected in series, and each second sub-slot can be connected to an energy storage component, so that the number of energy storage components can be connected according to demand, thereby increasing the amount of storage energy when powering the corresponding component to be powered.

[0092] Through the above embodiments, the energy storage device is configured as a transfer device connected between the power supply and the power input port on the server mainboard, so that the power supply can charge the energy storage device on the one hand, and on the other hand, the power supply can also be connected to the power input port on the server mainboard through the energy storage device to realize power supply to the server mainboard. At the same time, the energy storage device can also directly connect to the power input port on the server mainboard to supply power. Therefore, the problem of the interface occupation on the server mainboard for accessing an external energy storage device is effectively solved, and the access efficiency of the energy storage device is improved.

[0093] As an optional embodiment, the energy storage component includes a plurality of energy storage units, and the plurality of energy storage units are connected in series in sequence.

[0094] As an optional embodiment, the energy storage unit includes a super capacitor and a balancing resistor, and the super capacitor and the balancing resistor are connected in parallel.

[0095] Optionally, in the embodiment of the present application, Figure 6 is a schematic diagram of an energy storage component according to an embodiment of the present application, such as Figure 6 As shown, the energy storage component includes multiple energy storage units, which are connected in series, and each energy storage unit includes a super capacitor (device C in the figure) and a balancing resistor (device R in the figure) connected in parallel.

[0096] As an optional embodiment, the energy storage unit includes a solid electrolytic capacitor.

[0097] Optionally, in an embodiment of the present application, a solid-state electrolytic capacitor is a capacitor based on a solid electrolyte, which has the characteristics of high reliability, long life, low equivalent series resistance, and strong stability. The solid-state electrolytic capacitor can be, but is not limited to, an organic semiconductor aluminum electrolytic capacitor, a polymer conductor aluminum electrolytic capacitor, etc., and can also be a supercapacitor plate composed of solid electrolyte, which is not limited in this solution.

[0098] As an optional embodiment, the energy storage component includes a plurality of energy storage units and a second controller, the plurality of energy storage units have different electrical energy capacities, the plurality of energy storage units are connected in parallel, and the second controller is connected to each of the energy storage units.

[0099] The second controller is used to control a target energy storage unit among the plurality of energy storage units whose state type matches the target operating state to be in a state of supplying power to the target component.

[0100] Optionally, in an embodiment of the present application, the second controller is used to select an energy storage unit with different power capacities that can supply the target component with the remaining power required by the target component when the power supply is insufficient to supply the target component with the remaining power required by the target component. The second controller can be but is not limited to a CPU, an MCU (MicroController Unit), a DSP (Digital Signal Processor), etc., and this solution does not limit this.

[0101] Optionally, in an embodiment of the present application, the peak power demand of the component to be powered is different under different state types of the target operating state. For example, taking the component to be powered as a graphics processor as an example, the graphics processor may have multiple state types under the overclocking model operation, and the peak power demand of the server is different under different state types. For example, the peak power demand under the first state type is 110% of the total power of the power supply, the peak power demand under the second state type is 130% of the total power of the power supply, and the peak power demand under the third state type is 150% of the total power of the power supply.

[0102] Optionally, in the embodiment of the present application, in order to meet the power supply requirements of the components to be powered on the server mainboard under target operating states of different state types, a plurality of energy storage units connected in parallel can be configured. The electric energy capacity of different energy storage units is different. Therefore, by controlling the energy storage units connected to the components to be powered, it is possible to select a suitable energy storage unit for power supply according to the power supply requirements of the components to be powered, thereby improving the power supply efficiency of the energy storage unit to the power supply components. Figure 7 A schematic diagram of a controller controlling power supply of an energy storage unit according to an embodiment of the present application Figure 3 ,like Figure 7As shown, a multi-level energy storage unit structure is constructed by connecting multiple units in parallel. Energy storage units of different levels have different electric 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 receiving port of the component to be powered. The second controller is connected to each capacitor. Since the target component has different demands for electric energy under the target operating state, and the charging speeds of energy storage units with different electric energy capacities are also different, the control logic for controlling the energy storage unit to power the target component can be set in the second controller. That is, the controller can select an energy storage unit with an electric energy capacity that meets the remaining electric energy required to supply the GPU from among the energy storage units with different electric energy capacities to charge the GPU according to the operating mode information of the GPU (here the target component takes the GPU as an example) (that is, the remaining electric energy required by the GPU when the power supply is insufficient).

[0103] Through the above configuration, by connecting multiple energy storage units with different electric energy capacities in parallel, a circuit structure of a multi-level energy storage unit is realized, and then by connecting the second controller to the energy storage unit of each level, the power supply state of the energy storage unit of each level to the target component can be controlled, and then the energy storage unit of the corresponding level is selected to power the component to be powered according to the power supply demand of the component to be powered, thereby improving the adaptability between the energy storage unit and the power demand of the component to be powered, avoiding the problem of poor charging time of the energy storage device after using a high-level energy storage unit to power a component with a low-level power supply demand, thereby improving the power supply efficiency to the component.

[0104] As an optional embodiment, the energy storage unit includes a capacitor and a second control switch, the second control switch is connected to a second power supply link between the capacitor and the discharge port, and the second control switch is also connected to the second controller;

[0105] The second controller is used to adjust the closed state of the second control switch;

[0106] The second control switch is used to adjust the on / off state of the second power supply link.

[0107] Optionally, in an embodiment of the present application, the second control switch is a component used to adjust the on / off state of the power supply link. The second control switch can be, but is not limited to, an electronic switch, a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), etc., and this solution does not limit this.

[0108] According to the above content, by configuring the second control switch in each level of energy storage unit, the controller controls the on-off state of the second control switch to control the power supply state of the energy storage unit of the corresponding level to the power supply component, thereby improving the accuracy of control.

[0109] As an optional embodiment, the energy storage unit includes a capacitor and a second signal collector, wherein the second signal collector is connected to a second power supply link between the capacitor and the discharge port, and the second signal collector is also connected to the second controller;

[0110] The second signal collector is used to collect discharge information of the capacitor and send the discharge information to the second controller;

[0111] The second controller is used to detect the power supply information of the power supply to the server mainboard when it is determined that the discharge information indicates that the capacitor is in a discharged state; and control the power supply to charge the capacitor when the power supply information is used to indicate that the power demand of the server mainboard is less than the power supply of the power supply.

[0112] Optionally, in an embodiment of the present application, the second signal collector is used to collect voltage changes on the capacitor link during the capacitor indication process. The second signal collector can be but is not limited to a power amplifier, a voltage sensor, etc., and this solution does not limit this.

[0113] Optionally, in the embodiment of the present application, Figure 8 A schematic diagram of a controller controlling power supply of an energy storage unit according to an embodiment of the present application Figure 4 ,like Figure 8 As shown, each energy storage unit includes a capacitor ( Figure 8 The first-level capacitor, the second-level capacitor, the third-level capacitor) and the second control switch ( Figure 8Q1, Q2, Q3 in the figure, the control switch is MOS (Metal-Oxide-Semiconductor Field-Effect Transistor), the switches Q1, Q2, Q3 are connected to the power supply link between the corresponding capacitor and the corresponding sub-discharge port deployed on the energy storage component configuration board, the switches Q1, Q2, Q3 are also connected to the second controller, the second controller is used to adjust the closing state of the switches Q1, Q2, Q3, when the controller chooses to call the first-level capacitor to power the GPU (here the target component is GPU as an example), the control switch Q1 is closed, and the control switches Q2 and Q3 are disconnected. Similarly, when the controller chooses to call the second-level capacitor to power the GPU, the control switch Q2 is closed, and the control switches Q1 and Q3 are disconnected. After the power supply is completed, the second controller can also detect the charging state of the capacitor in the energy storage unit of the corresponding level through the signal acquisition resistor and the signal collector in the energy storage unit of the corresponding level. The second control unit collects the voltage change state at both ends of the signal acquisition resistor through the signal collector, thereby outputting a voltage signal for characterizing the discharge state of the capacitor, and then determining the charging and discharging state of the corresponding capacitor according to the voltage signal. After the capacitor is in the discharge state, the second control switch in the charging unit of the corresponding level is controlled to be in a closed state, and the second control switches in the energy storage units of other levels are controlled to be in an open state, thereby controlling the power supply to charge the capacitor.

[0114] In the above-mentioned application embodiment, in order to optimize the charging efficiency of the capacitor, when the second controller detects that the capacitor needs to be charged, it can predict the power supply demand information of the component to be powered in the future time period based on the operation model information of the component to be powered between the current time and the current power supply state of the power supply to the server motherboard is obtained when the power supply demand information indicates that the component to be powered needs to be powered by the target capacitor to be charged. When the power supply state indicates that the remaining power supply of the server power supply is less than the target power, the target capacitor in the target energy storage unit can be powered by other energy storage units other than the target energy storage unit in the multi-level energy storage unit. Therefore, the candidate energy storage device for charging the target capacitor can be screened out from other energy storage units according to the power demand of the target capacitor, and then the target energy storage unit and the second energy storage unit in the candidate energy storage unit are controlled. The switch is controlled to close in such a way as to control the closing of the connection link between the target energy storage unit and the candidate energy storage unit, so that the capacitor in the candidate energy storage device can charge the target capacitor. Through the above content, the second controller uses the historical power supply demand information of the component to be powered to predict the future power supply demand information of the component to be powered, so that after predicting that the target capacitor to be charged will be used to power the component to be powered, the power supply status of the power supply is detected, and then when the power supply is currently unable to charge the target capacitor, the target capacitor is charged through other energy storage units in the multi-level energy storage unit. On the one hand, the impact of charging the target capacitor on the power supply of the server motherboard can be avoided, and on the other hand, the target capacitor to be used can be charged through other energy storage units, thereby improving the timeliness of energy storage of the target capacitor and ensuring the power supply efficiency of the target capacitor to the component to be powered.

[0115] Optionally, in an embodiment of the present application, the controller can predict the power supply demand of the capacitor based on the operating mode information of the GPU. If the controller predicts that the first capacitor will soon need to power the component to be powered, but detects that the first capacitor is currently in a discharged state, and detects that there is no remaining power after the server power supply supplies power to the server mainboard, then the controller will detect the current discharge information of the second capacitor. When it is detected that the second capacitor is currently in an undischarged state, the controller will control the second capacitor to charge the first capacitor, that is, control switches Q1 and Q2 to close and Q3 to disconnect. At this time, the first capacitor and the second capacitor form a closed loop, and the second capacitor can be controlled to charge the first capacitor.

[0116] Through the above configuration, when the controller detects that the capacitor is in a discharged state, on the one hand, it can control the server power supply to charge the capacitor when there is surplus power in the server power supply. On the other hand, when the server power supply has no surplus power, it can control the capacitors to charge each other, which can improve the power supply efficiency of the capacitor to the powered components and avoid business waiting.

[0117] When the GPU (Graphics Processing Unit) in the server is overclocked, the peak load EDPp (Electric Design Peak Power) of the PSU is 155% of the maximum load for 200us, and the power supply will have concerns about triggering overcurrent protection (OCP). This power supply supports current protection (OCP) of 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 requirements of the overclocking peak load of the graphics processor in the server, additional capacitors can be added to support the overclocking peak load EDPp. The method is as follows: Design a capacitor plate to use large capacitors to support the overclocking peak load EDPp. It is necessary to design a super capacitor plate composed of 30 1200u, 16v solid electrolytes, and its capacitance value is about = 1200uF*30 = 36000uF = 0.036F. First, introduce the 12V power supply into the capacitor plate and then connect it to the GPU to complete the support of the GPU EDPp function. Fig. 9 is a schematic diagram of an optional capacitor plate according to an embodiment of the present application, such as Fig. 9 As shown, the capacitor board in the system mainly serves as energy storage filtering for the 12V power supply of 4GPUs to ensure the normal power supply of GPUs under instantaneous large loads. The capacitor board includes: 12V input charging port, 4 12V discharge ports (as shown in the figure above: C0\C1\C2\C3), 30 1200uf, 16v solid aluminum electrolytic capacitors (only 16 are shown in the figure) to form a capacitor array. Connection relationship: The capacitor board takes 12V power from the motherboard through 4 2x4 power supply adapters (the motherboard charging port), and after energy storage through the capacitor array, it is connected to the GPU0\GPU1\GPU2\GPU3 power supply interface through another 4 2x4 power supply adapters to realize the power supply of 4 GPUs.

[0118] The above method: add additional capacitor plates to support the peak load EDPp during overclocking: This method will not affect the PSU design and power supply cost. However, it is necessary to find a corresponding space in the system to place the capacitor plate, generally a slot space corresponding to the PCIe function expansion card will be found for placement. However, this will occupy the slot space of the PCIe function expansion card, affecting the system function expansion, resulting in limited configuration and insufficient system space, thus affecting market competitiveness.

[0119] In order to optimize the above problems, a minimized supercapacitor board (supporting 4 12V GPUs) can be designed and directly combined with the PSU: use supercapacitors 220mF / 4.2V in series 6 = 220mF / 6 = 0.036F with a withstand voltage of 25.2V. And match with balancing resistors 10K ohm / 0402* 6. The size of the supercapacitor board is 100mm*28mm*1.6mm. The supercapacitor board has a PSU input connector and an output gold finger. The input connector is connected to the PSU, and the output gold finger connector is connected to the system motherboard. Fig.10 is an optional supercapacitor board equivalent circuit diagram according to an embodiment of the present application, such as Fig.10 As shown, the input connector (PSU conn input) (i.e., charging port) of the supercapacitor board is connected to the PSU, and the output golden finger connector (GoldenFinger Output) (i.e., discharge port) is connected to the system motherboard. The input connector and the output golden finger connector are connected through a connection link. Multiple supercapacitors (6 are shown in the figure, C is a supercapacitor) and multiple balancing resistors (R is a balancing resistor) are connected in series and bridged between the connection links (one supercapacitor is connected in parallel with one balancing resistor). Supports instantaneous EDPp peak power capacitance value design:

[0120] It is expected to design a 1300W output 12.2V supercapacitor that can support the new generation GPU 197% for 200uS. The peak current Ipeak required to support the 1300W EDPP curve is calculated as follows: Ipeak=Pout / Vout*EDPp=1300W / 12.2V*1.97=210A.

[0121] Capacitance calculation:

[0122] Supports single instantaneous capacitance value design from 5A to 210A for 200u Sec. Allowable support voltage range is + / - 7%. Support voltage range is 12.8V ~ 11.6V.

[0123] Supercapacitor calculation formula:

[0124]

[0125] => 12.2V * (210A-5A) *200uF = 1 / 2 *C* (12.8 2 -11.6 2 ),

[0126] => C= 34166 uF => 36000uF or 0.036F supercapacitor can be selected.

[0127] Do not exceed the maximum capacitive load of the PSU (1300W PSU Cap load Max is 50000uF).

[0128] The board supports current analysis:

[0129] The supercapacitor charge formula is Q = I * t = C* dV,

[0130] Capacitor rated capacity; Q: capacitance; dv: capacitor operating voltage difference; I: capacitor discharge current; t: capacitor discharge time; R: capacitor internal resistance.

[0131] Theoretical support current:

[0132] C: Capacitance value V: Capacitor voltage I = current during charging and discharging, dV actual voltage difference is 12.6V-11.4V,

[0133] Q = C * dV = 0.036F * (12.6-11.4) = 0.0432 C = 0.0432A. s = 43.2mA. s.

[0134] In actual situation, if the discharge current required to support 200us is:

[0135] 0.0432A . s = 43.2mA . s ==> 43.2mA . s / 200us = 216A;

[0136] In actual situation, if the discharge current needs to support 1ms, the current is:

[0137] 0.0432A . s = 43.2mA . s ==> 43.2mA . s / 1ms = 43.2A;

[0138] In actual situation, if the discharge current needs to be supported for 50ms, the discharge current is:

[0139] 0.0432A . s = 43.2mA . s ==> 43.2mA . s / 50ms = 0.864A;

[0140] In actual situation, if the discharge current needs to support 20us, the current is:

[0141] 0.0432A . s = 43.2mA . s ==> 43.2mA . s / 20us = 2160 A;

[0142] Through the above embodiment, it can be expanded by directly connecting to the PSU and the motherboard, without occupying the slot space of the PCIe PCIe function expansion card, affecting the system function expansion and causing limited configuration and insufficient system space, thus affecting market competitiveness. The design is simple, the minimization is high in stability, and it does not affect the system layout space.
