Multiple power supply trays and power supply transfer trays are disposed within a first cabinet of the power supply system, and the multiple conductive row groups are embedded within the multiple power supply trays and power supply transfer trays along a first direction perpendicular to the backs of the multiple power supply trays and power supply transfer trays. This significantly saves space within the power supply system when no server nodes are contained within the first cabinet, and multiple power supply trays can be disposed within the first cabinet to generate a target voltage that can meet high power requirements and a target current corresponding to the target voltage.

In addition, by providing a plurality of conductive row groups, the plurality of conductive row groups can be used to share the target current corresponding to the target voltage, reducing the current flowing through each conductive row group and the current in the contact area between each conductive row group and the power supply transfer tray and the plurality of power supply trays, thereby reducing the current loss and load of each conductive row group, avoiding the temperature increase of the local area of the power supply system due to high load and high current loss, and then using conductive row groups with smaller cross-sectional areas, reducing the volume of the power supply system, and improving the safety of the power supply system and the space utilization rate.

[0009] According to an embodiment of the present application, after receiving the target voltage gathered by multiple conductive row groups, the power supply adapter tray transmits the target voltage to an independent server independent of the power supply system through an external cable, so that each server module in the server can receive high power that matches the high computing power.

[0037] A rack server is a cabinet device that integrates multiple server nodes and the power supply equipment used to power these server nodes. With the development of technology, the computing power demand for server nodes is increasing, necessitating server nodes composed of more servers to meet this increased computing power demand. However, as the computing power demand for server nodes increases, the power demand required by these server nodes is also increasing.

[0038] An embodiment of the present application provides a power supply system, comprising: multiple power supply trays, used to convert and boost multiple input voltages respectively to obtain target voltages and output them to a power supply transfer tray; a power supply transfer tray, comprising multiple power supply terminals, wherein the first ends of the multiple power supply terminals are electrically connected to the conductive path in the circuit board of the power supply transfer tray, and the second ends of the multiple power supply terminals are used to be electrically connected to an external cable, transmitting the target voltage in the conductive path to the multiple power supply terminals, so that the target voltage is transmitted to the external load through the external cable; multiple conductive row groups are embedded in the multiple power supply trays and the power supply transfer tray along a first direction perpendicular to the backs of the multiple power supply trays and the power supply transfer tray, and are used to electrically connect the multiple power supply trays and the power supply transfer tray, so that the target voltage generated by the multiple power supply trays is converged to the power supply transfer tray through the multiple conductive row groups.

[0039] In some embodiments, a full-rack server needs to include a large number of servers, each interconnected through a topological network to form a super-node computing power group. If a super-node computing power group is dispersed across multiple full-racks, the bandwidth within the computing power group will be greatly reduced, thereby affecting computing power. Therefore, the number of server nodes in a full-rack is almost fixed and cannot be arbitrarily reduced. However, the space size within the full-rack is limited. After installing a large number of servers, the space for installing the power supply device is very limited.

[0040] In some embodiments, as the computing power of the server increases, the power consumption also increases, and thus the power requirements for the entire cabinet are also increasing. The core component of the power supply device is the power supply unit, which can convert AC power into the DC power required by the server. Due to the size limitation of the entire cabinet, the number of power supply units that can be accommodated by the power supply device in the entire cabinet is relatively small, so the power is too low to meet the power requirements of the server. And as the power of the server increases, under a certain power, due to the low voltage of the 54V DC power supply used, the current flowing through the copper busbar becomes larger and larger, causing the current loss on the copper busbar to increase sharply.

[0041] According to an embodiment of the present application, a power supply system may include a plurality of power supply trays, a power supply transfer tray, and a plurality of conductive bank groups, wherein the power supply transfer tray includes a plurality of power supply terminals.

[0042] The power supply system may further include a first cabinet, wherein a plurality of power supply trays and power supply transfer trays may be arranged in the first cabinet. No server node is arranged in the first cabinet of the power supply system.

[0043] According to an embodiment of the present application, a plurality of power supply trays are used to convert and boost a plurality of input voltages respectively, obtain target voltages, and output the target voltages to the power supply adapter tray.

[0044] The input voltage can be AC power, and the relevant power supply structure in the power supply tray needs to be used to convert the AC power into DC power, and perform a voltage boost process on it to obtain a target voltage and a target current corresponding to the target voltage to meet the high power requirements of the server. Specifically, the voltage value of the target voltage can be adjusted and increased according to the needs of the server. For example, the input voltage can be 220V AC power, and after conversion and voltage boosting by multiple power supply trays, a target voltage of 440V DC power can be obtained. In addition, since no server nodes are provided in the first cabinet of the power supply system, more power supply trays can be provided to improve the space utilization in the first cabinet of the power supply system.

[0045] According to an embodiment of the present application, the power supply tray includes multiple power supply terminals, the first ends of the multiple power supply terminals are electrically connected to the conductive path in the circuit board of the power supply adapter tray, and the second ends of the multiple power supply terminals are used to electrically connect to the external cable, transmitting the target voltage in the conductive path to the multiple power supply terminals, so that the target voltage is transmitted to the external load through the external cable.

[0046] The peripheral load may be an independent server cabinet installed outside the power supply system.

[0047] According to an embodiment of the present application, a plurality of conductive row groups are embedded in a plurality of power supply trays and a power supply adapter tray along a first direction perpendicular to the backs of the plurality of power supply trays and the power supply adapter trays, and are used to electrically connect the plurality of power supply trays and the power supply adapter trays so that the target voltage generated by the plurality of power supply trays is converged to the power supply adapter tray through the plurality of conductive row groups.

[0048] The first direction may be a direction outside the first cabinet of the power supply system and perpendicular to the backs of the plurality of power supply trays and the power supply transfer tray. The conductive busbar group may be a copper busbar group including a positive copper busbar and a negative copper busbar.

[0049] By embedding multiple conductive bank groups, multiple power supply trays and power supply transfer trays can be interconnected through the multiple conductive bank groups, so that the target voltage generated in the multiple power supply trays and the target current corresponding to the target voltage can be transmitted to the power supply transfer tray, and then the power supply transfer tray supplies power to servers independent of the power supply system. Furthermore, by connecting multiple power supply trays and power supply transfer trays with multiple conductive bank groups, the target current can be shared by multiple conductive bank groups, reducing the current flowing through each conductive bank group, thereby reducing the current loss, load and cross-sectional area of each conductive bank group. At the same time, the current in the contact area between each conductive bank group and the power supply transfer tray and multiple power supply trays can be reduced, preventing the temperature increase caused by excessive current from damaging the power supply system.

[0050] According to an embodiment of the present application, a power supply system may include multiple power supply trays, power supply transfer trays, and multiple conductive row groups, wherein the power supply transfer trays include multiple power supply terminals, and the power supply system does not contain any server nodes. Multiple power supply trays and power supply transfer trays are disposed within a first cabinet of the power supply system, and the multiple conductive row groups are embedded within the multiple power supply trays and power supply transfer trays along a first direction perpendicular to the backs of the multiple power supply trays and power supply transfer trays. This significantly saves space within the power supply system when no server nodes are contained within the first cabinet, and multiple power supply trays can be disposed within the first cabinet to generate a target voltage that can meet high power requirements and a target current corresponding to the target voltage.

[0051] According to an embodiment of the present application, an external power supply can simultaneously input multiple input voltages to multiple power supply trays. Multiple power supply trays perform AC to DC conversion and boost processing on the multiple input voltages to obtain the target voltage, thereby realizing the processing of the input voltage so that the input voltage can be converted into a high DC voltage that is suitable for the normal operation of the server and can meet the power requirements of multiple high-computing power server modules.

[0052] According to an embodiment of the present application, after a plurality of power supply trays generate a target voltage, they are transmitted to a plurality of conductive row groups. The plurality of conductive row groups electrically connect the plurality of power supply trays and the power supply transfer tray, so that the target voltage can be converged into the power supply transfer tray through the plurality of conductive row groups, thereby realizing the transfer of the target voltage. In addition, by providing a plurality of conductive row groups, the plurality of conductive row groups can be used to share the target current corresponding to the target voltage, reducing the current flowing through each conductive row group and the current in the contact area between each conductive row group and the power supply transfer tray and the plurality of power supply trays, thereby reducing the current loss and load of each conductive row group, avoiding the temperature increase of the local area of the power supply system due to high load and high current loss, and then using conductive row groups with smaller cross-sectional areas, reducing the volume of the power supply system, and improving the safety of the power supply system and the space utilization rate.

[0053] According to an embodiment of the present application, after receiving the target voltage gathered by multiple conductive row groups, the power supply adapter tray transmits the target voltage to an independent server independent of the power supply system through an external cable, so that each server module in the server can receive high power that matches the high computing power.

[0054] Figure 1 A schematic diagram of a power supply system according to an embodiment of the present application is shown.

[0055] like Figure 1 As shown, the power supply system may include a first cabinet 101, multiple power supply trays 102, a power supply transfer tray 103 and multiple conductive row groups 104, the power supply transfer tray 103 includes multiple power supply terminals 1031, the power supply transfer tray 103 is parallel to the multiple power supply trays 102, and the multiple conductive row groups 104 are embedded in the multiple power supply trays 102 and the power supply transfer tray 103 along a first direction perpendicular to the backs of the multiple power supply trays 102 and the power supply transfer tray 103.

[0056] According to an embodiment of the present application, the plurality of conductive bank groups may include at least one first conductive bank group and at least one second conductive bank group, and the power supply transfer tray may include a management tray and a transfer tray.

[0057] According to an embodiment of the present application, at least one first conductive row group can be set in the first area on the back of multiple power supply trays and management trays, for electrically connecting a part of the multiple power supply trays with the management tray, so that the target voltage generated by a part of the power supply trays is converged to the management tray.

[0058] The first area can be characterized as an area on the back of the management tray and a portion of the power supply tray. At least one first conductive row group needs to be electrically connected to the management tray and a portion of the power supply tray. At least one first conductive row group can converge the target voltage generated by multiple power supply trays in the first area to the management tray.

[0059] According to an embodiment of the present application, at least one second conductive row group can be arranged in a second area on the back of multiple power supply trays and an adapter tray, for electrically connecting another part of the multiple power supply trays with the adapter tray, so that the target voltage generated by the other part of the power supply trays is converged to the adapter tray, wherein the first area and the second area do not overlap.

[0060] The second region can be characterized as the area separated from the adapter tray and another portion of the power supply trays. At least one second conductive bank group needs to be electrically connected to the adapter tray and another portion of the power supply trays. The at least one second conductive bank group can converge the target voltage generated by multiple power supply trays in the second region to the adapter tray. The first conductive bank group and the second conductive bank group are not connected. There is no limit on the number of first conductive bank groups in the first region and the number of second conductive bank groups in the second region.

[0061] Based on the current thermal effect formula, assuming that there are a first conductive bar group and a second conductive bar group, the current flowing through each conductive bar group is half of that of a conductive bar group, so the loss of each conductive bar group can be the first loss value, that is, the total loss of the first conductive bar group and the second conductive bar group is only equivalent to half of that of a conductive bar group.

[0062] P = I²R (1);

[0063] Among them, P can be represented as thermal effect loss, I can be represented as current, R can be represented as load, and formula (1) is the current thermal effect formula.

[0064] P1=[(1 / 2)I]²R(2);

[0065] Here, P1 can be represented as a first loss value.

[0066] Thus, by sharing the load across multiple conductive bar groups, the load, heat generation, and losses of each conductive bar group can be reduced. Furthermore, even when using high-voltage direct current (DC), such as 400V DC, the current in each conductive bar group can be effectively reduced, allowing the use of first and second conductive bar groups with smaller cross-sectional areas.

[0067] According to an embodiment of the present application, multiple conductive bank groups include at least one first conductive bank group and at least one second conductive bank group, and the first conductive bank group and the second conductive bank group are respectively arranged in different areas, and different power supply trays are electrically connected to the management tray or the adapter tray, so that under the joint action of multiple conductive bank groups, the target voltage can be efficiently transmitted to the management tray and the adapter tray, and the current flowing through each conductive bank group and the current in the contact area between each conductive bank group and the power supply adapter tray and multiple power supply trays, as well as the cross-sectional area of the conductive bank group are reduced. Due to the reduction in the cross-sectional area of the conductive bank group, more first conductive bank groups and second conductive bank groups can be arranged on the limited first panel, thereby improving space utilization.

[0068] Figure 2 A schematic diagram of multiple conductive bar groups in a power supply system according to an embodiment of the present application is shown.

[0069] like Figure 2 As shown, the multiple conductive bar groups include two first conductive bar groups 201 and two second conductive bar groups 202. The two first conductive bar groups 201 are both located in the first area 205, and the two second conductive bar groups 202 are both located in the second area 206. Each first conductive bar group 201 includes a first positive copper bar 2011 and a first negative copper bar 2012, and each second conductive bar group 202 also includes a second positive copper bar 2021 and a second negative copper bar 2022. The two first conductive bar groups 201 electrically connect the management tray 203 and a portion of the power supply trays, and the two second conductive bar groups 202 electrically connect the adapter tray 204 and another portion of the power supply trays. It can be understood that Figure 2 The number of conductive row groups shown in FIG. 1 is only an example, and the embodiments of the present application are not limited thereto.

[0070] According to an embodiment of the present application, the management tray can be set on the upper side of multiple power supply trays in a direction parallel to the multiple power supply trays, and is used to manage and monitor the target voltages output by multiple power supply trays, and output the target voltages generated by some power supply trays to the external load.

[0071] According to an embodiment of the present application, the adapter tray can be arranged on the lower side of the multiple power supply trays in a direction parallel to the multiple power supply trays, and is used to output the target voltage generated by another part of the power supply trays to the peripheral load.

[0072] Figure 3 A schematic diagram of a management tray and a transfer tray according to an embodiment of the present application is shown.

[0073] like Figure 3 As shown, the management tray 203 in the first cabinet 101 is arranged on the upper side of the multiple power supply trays 102 along the vertical direction, and the adapter tray 204 is arranged on the lower side of the multiple power supply trays 102 along the vertical direction. The management tray 203, the multiple power supply trays 102 and the adapter tray 204 are electrically connected through multiple conductive row groups 104.

[0074] According to an embodiment of the present application, a first powered clamping component, a first circuit board, and a first power supply terminal may be provided in the management tray.

[0075] According to an embodiment of the present application, one side of the first powered clamping component is fixed on the first circuit board, and the other side of the first powered clamping component is used to clamp at least one first conductive strip group so that the target voltage gathered by the at least one first conductive strip group is transmitted to the first circuit board.

[0076] The first power receiving clamping assembly may be a first power receiving clamp group, and the first power receiving clamping device in the assembly may be a first power receiving clamp, that is, the first power receiving clamp group may include at least one first power receiving clamp, and the number of first power receiving clamps is not limited.

[0077] According to an embodiment of the present application, a first circuit board is arranged inside the management tray, and a first conductive path is arranged on the first circuit board. The first conductive path is used to transmit the target voltage to the first power supply terminal so that the first power supply terminal outputs the target voltage and target current to the external load through an external cable.

[0078] A first end of the first conductive path is electrically connected to the first power supply terminal, and a second end of the first conductive path is electrically connected to at least one first power receiving clamp in the first power receiving clamping assembly. The number of first conductive paths can correspond to the number of first power receiving clamps in the first power receiving clamping assembly, and the number of first conductive paths is not limited.

[0079] According to an embodiment of the present application, the first power supply terminal is arranged on the upper side of the back of the management tray, the first end of the first power supply terminal is electrically connected to the first conductive path, and the second end of the first power supply terminal is electrically connected to the external cable, for receiving the target voltage in the first conductive path, and electrically connected to the external load through the external cable to transmit the target voltage to the external load.

[0080] According to an embodiment of the present application, the management tray may further include a management connector and a management controller.

[0081] According to an embodiment of the present application, the management connector is used to forward serial status signals corresponding to the plurality of power trays to the management controller.

[0082] The management connector may be provided on the back of the management tray.

[0083] According to an embodiment of the present application, the management controller is used to generate multiple power supply status information in response to receiving a serial status signal, and send multiple power supply status information to the interactive network port, wherein the interactive network port is arranged at the front of the management tray and is used to report multiple power supply status information to the external switching device.

[0084] The management connector and management controller can be connected via a signal path within the circuit board. Serial status signals can be transmitted to the management controller via the signal path. The management controller can be a controller such as a Baseboard Management Controller (BMC). Upon receiving the serial status signals forwarded by the management connector, the management controller parses the serial status signals to obtain power supply status information for multiple power trays. This power supply status information may include the current operating status of the power tray, the target voltage generated, the target current generated at the target voltage, whether the switch is on or off, the operating temperature, and the power tray's ID (identification number).

[0085] After parsing multiple power supply status information, the management controller can selectively send it to the interactive network port based on the power supply status information for reporting to the external switching device. For example, abnormal power supply status information can be pre-set to be sent to the interactive network port, allowing the external switching device to make decisions based on the received abnormal power supply status information. Normal power supply status information can be controlled and decided by the management controller. After parsing multiple power supply status information, the management controller can also send all of the power supply status information to the interactive network port for reporting to the external switching device, which can then make decisions and control.

[0086] The interactive network port and the management controller are connected via a signal path. After receiving multiple power supply status messages, the external switching device can make decisions about the corresponding power tray and send multiple decision signals to the interactive network port. These multiple decision signals are transmitted via the signal path to the management controller, which processes them to generate multiple serial decision signals. These signals are then forwarded to the corresponding power tray via the management connector.

[0087] According to an embodiment of the present application, the management controller may also be configured to generate serial control signals corresponding to the plurality of power supply trays according to the serial status signal, and send the serial control signals to the management connector.

[0088] The management controller can classify the power supply status information. When a serial status signal is received, it is parsed to obtain multiple power supply status information, and each power supply status information is judged and managed according to the preset three-level classification. When it is confirmed that the power supply status information is the third level, a serial control signal is generated according to the power supply status information. When it is confirmed that the power supply status information is the second level, the power supply status information is sent to the interactive network port for reporting to the external switching device, and the decision signal sent by the external switching device is waited for, and a serial control signal is generated based on the decision signal and the power supply status information. When it is confirmed that the power supply status information is the first level, the power supply status information is sent to the interactive network port while generating a first serial control signal based on the power supply status information, and the decision signal sent by the external switching device is waited for, and a second serial control signal is generated based on the decision signal and the power supply status information.

[0089] For example, three levels are preset based on the power supply status information: the first level is target voltage < 220V, target current < 1A, and operating temperature > 65°C; the second level is 220V ≤ target voltage ≤ 350V, 1A ≤ target current ≤ 10A, and operating temperature 45°C ≤ 65°C; and the third level is target voltage > 350V, target current > 10A, and operating temperature < 45°C. The management controller parses the serial status signal separately to obtain three power supply status information. The first power supply status information includes the first power supply tray, target voltage of 400V, target current of 16A, and operating temperature of 44°C; the second power supply status information includes the second power supply tray, target voltage of 10V, target current of 0.1A, and operating temperature of 70°C; and the third power supply status information includes the third power supply tray, target voltage of 600V, target current of 20A, and operating temperature of 55°C. If any condition in the power supply status information meets a specific level, the power supply status information is determined to belong to that level. Therefore, based on the three power supply status information, it is determined that the first power supply status information meets the third classification, the second power supply status information meets the first classification, and the third power supply status information meets the second classification.

[0090] Based on the determined classification of each power supply status information, the management controller generates a serial control signal to maintain operation based on the first power supply status information and sends it to the first power supply tray. Based on the second power supply status information, the management controller generates a serial control signal to suspend operation and sends it to the second power supply tray. Simultaneously, the second power supply status information is sent to the interactive network port. Upon receiving a decision from the external switching device, the external switching device stops processing the input voltage and turns on all fans in the power supply tray. The management controller then sends a second serial control signal to the second power supply tray to stop processing the input voltage and turn on all fans in the power supply tray based on the decision signal and the second power supply status information. Based on the third power supply status information, the management controller sends a serial control signal to the interactive network port to wait for a decision from the external switching device. A decision signal to the external switching device to stop operation and await maintenance is sent to the management controller. Based on the decision signal and the third power supply status information, the management controller sends a serial control signal to the third power supply tray to stop operation and await maintenance.

[0091] According to an embodiment of the present application, the management tray includes a first powered clamping assembly, a first circuit board, a first power supply terminal, a management connector, and a management controller. The first powered clamping assembly clamps at least one first conductive strip group to electrically connect a first conductive path to the at least one first conductive strip group. The first conductive strip group transmits a target voltage obtained by collecting it from a portion of the power supply tray to the first power supply terminal via the first conductive path. The first power supply terminal is electrically connected to an independent server via an external cable, thereby transmitting the target voltage to the server, allowing the server to perform normal business operations and other processing while meeting high power requirements.

[0092] According to an embodiment of the present application, further, in combination with the management connector and the management controller, the serial status signals corresponding to the multiple power supply trays are sent to the management connector through the signal path, and then the serial status signals are forwarded to the management controller. The management controller parses the serial status signals to obtain the power supply status information of the multiple power supply trays and sends them to the serial network port. The management controller then makes judgments based on the multiple status power supply information and the decision signals of the external switching equipment to generate multiple serial control signals, thereby achieving the effect of controlling the multiple power supply trays.

[0097] According to an embodiment of the present application, the adapter tray further includes a second power receiving clamping assembly, a second circuit board, and a second power supply terminal.

[0098] According to an embodiment of the present application, one side of the second powered clamping component is fixed on the second circuit board, and the other side of the second powered clamping component is used to clamp at least one second conductive strip group so that the target voltage gathered by the at least one second conductive strip group is transmitted to the second circuit board.

[0099] The second power receiving clamping assembly may be a second power receiving clamp group, and the second power receiving clamping device in the assembly may be a second power receiving clamp, that is, the second power receiving clamp group may include at least one second power receiving clamp, and the number of second power receiving clamps is not limited.

[0100] According to an embodiment of the present application, a second circuit board is arranged inside the adapter tray, and a second conductive path is arranged on the second circuit board. The second conductive path is used to transmit the target voltage to the second power supply terminal so that the second power supply terminal outputs the target voltage to the external load through an external cable.

[0101] A first end of the second conductive path is electrically connected to the second power supply terminal, and a second end of the second conductive path is electrically connected to at least one second power receiving clamp in the second power receiving clamping assembly. The number of second conductive paths can correspond to the number of second power receiving clamps in the second power receiving clamping assembly, and the number of second conductive paths is not limited.

[0102] According to an embodiment of the present application, the second power supply terminal is arranged on the lower side of the back of the adapter tray, the first end of the second power supply terminal is electrically connected to the second conductive path, and the second end of the second power supply terminal is electrically connected to the external cable for receiving the target voltage in the second conductive path and electrically connected to the external load through the external cable to transmit the target voltage to the external load.

[0103] According to an embodiment of the present application, the adapter tray includes a second power receiving clamping assembly, a second circuit board, and a second power supply terminal. A second conductive path is arranged on the second circuit board. The second power receiving clamping assembly clamps at least one second conductive bank group to electrically connect the second conductive path and the at least one second conductive bank group. The second conductive bank group transmits the target voltage obtained by convergence via the second conductive path to the second power supply terminal.

[0104] Figure 6 A cross-sectional view of the internal structure of an adapter tray according to an embodiment of the present application is shown.

[0105] like Figure 6 As shown, the adapter tray 204 may be provided with a second power receiving clamp group 601, a second circuit board 602, and a second power supply terminal 603. The second circuit board 602 is provided with a second conductive path 6021. The second power receiving clamp group 601 includes two second power receiving clamps. The two second power receiving clamps and the second power supply terminal 603 may be electrically connected via the second conductive path 6021. It is understood that Figure 6 The number of the second power supply terminals shown in FIG. 1 is only an example, and the embodiments of the present application are not limited thereto.

[0106] Figure 7 A side view of the internal structure of an adapter tray according to an embodiment of the present application is shown.

[0107] like Figure 7 As shown, the management tray 204 includes two second power receiving clamps 6011 and a second power supply terminal 603 , and the power receiving clamps and the second power supply terminal are electrically connected via a second conductive path 6021 .

[0108] According to an embodiment of the present application, the number of the powered clamping devices in the first powered clamping assembly is equal to the number of copper bars in the first conductive bar group, and the number of the powered clamping devices in the second powered clamping assembly is equal to the number of copper bars in the second conductive bar group.

[0109] According to an embodiment of the present application, a plurality of conductive bank group slots compatible with the plurality of conductive bank groups are provided on the back of the plurality of power supply trays, the management tray and the adapter tray, so that when the plurality of conductive bank groups are inserted into the plurality of conductive bank group slots, the plurality of conductive bank groups are clamped by the first powered clamping device group or the second powered clamping device group and are electrically connected to the management tray, the adapter tray and the plurality of power supply trays.

[0110] Figure 8 A schematic diagram of multiple conductive row slots according to an embodiment of the present application is shown.

[0111] like Figure 8 As shown, a plurality of conductive row group grooves 801 are arranged in the first area and the second area on the back of the management tray 203 and the adapter tray 204 of the first cabinet 101 .

[0112] According to an embodiment of the present application, a plurality of retractable conductive bank positioning pins are provided within the conductive bank slot. These retractable conductive bank positioning pins are disposed at the corners of the conductive bank slot and are spaced a predetermined depth from the bottom of the conductive bank slot. When the conductive bank is inserted into the conductive bank slot, the retractable conductive bank positioning pins abut against the conductive bank positioning slots, allowing the conductive bank to be inserted into the conductive bank slot to a predetermined depth and clamped by the first or second power receiving clamping device groups.

[0113] Positioning slots can be provided at predetermined locations on the corners of the conductive bank assembly. This allows the retractable conductive bank positioning pins to engage with the positioning slots after the conductive bank assembly is inserted into the conductive bank assembly slot, thereby securing the conductive bank assembly and maintaining its insertion depth. The retractable conductive bank positioning pins in the conductive bank assembly slot can be screw-shaped or right-angled, and the shape of the retractable conductive bank positioning pins is not limited herein.

[0114] According to an embodiment of the present application, a plurality of conductive bank slots, each adapted for a plurality of conductive bank groups, are provided on the back of a plurality of power supply trays, a management tray, and an adapter tray. A plurality of retractable conductive bank positioning pins can be provided in each conductive bank slot. The plurality of retractable conductive bank positioning pins are respectively provided at the corners of the conductive bank slots and are spaced a predetermined depth from the bottom of the conductive bank slots. When the conductive bank group is inserted into the conductive bank group groove, the plurality of retractable conductive bank group positioning pins can be used to clamp the conductive bank group at a predetermined depth, so that the conductive bank group can be stably and firmly clamped in the conductive bank group groove, avoiding the problem of being unable to be clamped by the first power receiving clamping device group or the second power receiving clamping device group due to tolerance problems caused by the short size, thereby improving the design stability of the conductive bank group and reducing problems such as the conductive bank group being poorly inserted due to tolerance problems of the conductive bank group.

[0115] Figure 9 A schematic diagram showing the internal structure of the conductive row slots of the adapter tray according to an embodiment of the present application is shown.

[0116] like Figure 9 As shown, a plurality of retractable conductive row group positioning pins 901 may be provided at the corners of the conductive row group slot 801 .

[0117] Due to the tolerance problem of the conductive row group, even when the conductive row group is inserted into the conductive row group slot, it may not be clamped by the first powered clamping device or the second powered clamping device. Therefore, an elastic structure of the clamping device can be set in the first powered clamping device and the second powered clamping device, and an adjustable clamping plate can be set in the first powered clamping device or the second powered clamping device. When the copper busbar cannot be clamped due to the tolerance problem, the copper busbar can be abutted against the elastic structure of the clamping device through the elastic structure of the clamping device. An adjustable clamping plate can also be set on the elastic structure of the clamping device. By adjusting the length of the adjustable clamping plate, the copper busbar with a large tolerance problem can be tightly clamped. An adjustable clamping plate can also be set at the bottom of the clamping device. By adjusting the telescopic distance of the adjustable clamping plate, the copper busbar with a large tolerance problem can also be tightly clamped. By introducing an elastic structure of the clamping device and an adjustable conductive plate into the clamping device (clip), combined with multiple retractable conductive bar positioning pins in the conductive bar group slot, multiple insurances can be provided for the insertion and clamping of the conductive bar group, thereby greatly reducing the risk of conductive bar group virtual clamping due to tolerance problems and improving the reliability of the power receiving clamping device and the conductive bar group slot.

[0118] Figure 10 A schematic diagram of a powered clamping device according to an embodiment of the present application is shown.

[0119] like Figure 10 As shown, the powered clamping device may include a first clamping plate 1001 and a second clamping plate 1002. The first clamping plate 1001 and the second clamping plate 1002 can be used to control the tightness of the powered clamping device by two first adjustable screws 1003. The elastic structure 1004 of the clamping device is arranged in the first clamping plate 1001 and the second clamping plate 1002. When the copper busbar with tolerance problems is clamped by the clamping device, it will first abut against the elastic structure 1004 of the clamping device, and then the two clamps tighten the elastic structure of the clamping device.

[0120] Figure 11 A schematic diagram of a powered clamping device according to another embodiment of the present application is shown.

[0121] like Figure 11As shown, the power receiving clamping device may further include a clamping device elastic structure 1004 and an adjustable clamping plate, the adjustable clamping plate being fixed on the clamping device elastic structure 1004, the adjustable clamping plate may include a retractable spiral structure 1101 and a copper busbar clamping device 1102, when a copper busbar with a tolerance problem is inserted into the copper busbar slot, due to insufficient depth of the copper busbar and limited length of the original clamping device elastic structure 1004, the retractable spiral structure 1101 may be adjusted to increase the length of the copper busbar clamping device, so that the copper busbar clamping device 1102 may be in contact with the copper busbar, and then the two first adjustable screws 1003 between the first clamping plate 1001 and the second clamping plate 1002 may be tightened to make the entire power receiving clamping device and the copper busbar more stable and firm.

[0122] Figure 12 FIG. 1 is a schematic diagram of a powered clamping device according to another embodiment of the present application.

[0123] like Figure 12 As shown, the power receiving clamping device can also include only adjustable clamping plates. The two adjustable clamping plates are arranged at the bottom of the two clamping plates of the clamping device. The distance between the copper bar clamping device 1102 and the bottom of the clamping plates is adjusted by a second adjustable screw 1201. The copper bar clamping device 1102 is fixed to the connecting plate 1202. When a copper bar with tolerance issues is inserted into the copper bar slot, due to insufficient depth of the copper bar, the second adjustable screw 1201 can be adjusted to bring the copper bar clamping device 1102 closer to the copper bar and abut against the copper bar.

[0124] According to an embodiment of the present application, the power supply system further includes a power supply management expansion board. The power supply management expansion board is disposed outside the plurality of power supply trays and the power supply adapter tray in a first direction perpendicular to the backs of the plurality of power supply trays and the power supply adapter tray, and is configured to transmit a plurality of status signals output by the plurality of power supply trays to the management tray.

[0125] Each power supply tray can generate a status signal based on the working status and internal temperature, and transmit the status signal to the management tray.

[0126] Figure 13 A schematic diagram of a power supply management expansion board according to an embodiment of the present application is shown.

[0127] like Figure 13 As shown, in the first area 205, the first positive copper busbar 2011 and the first negative copper busbar 2012 of the two first conductive busbar groups electrically connect the management tray 203 and a portion of the power supply trays, and in the second area 206, the second positive copper busbar 2021 and the second negative copper busbar 2022 of the two second conductive busbar groups electrically connect the adapter tray 204 and another portion of the power supply trays, and the power supply management expansion board 1301 is set outside the first cabinet 101.

[0128] According to an embodiment of the present application, a signal controller is provided in the power management expansion board. The signal controller is configured to decode the multiple status signals in response to receiving the multiple status signals, obtain a serial status signal that meets the predetermined protocol format, and transmit the serial status signal to the management connector.

[0129] According to an embodiment of the present application, the signal controller is also used to encode the serial control signal in response to receiving the serial control signal generated by the management controller to obtain multiple control signals so that multiple power supply trays switch power supply states under the control of the multiple control signals.

[0130] The signal controller receives multiple status signals from multiple power supply trays and transmits multiple control signals to multiple power supply trays through signal lines. It can also transmit decoded serial status signals to the management connector through signal lines and receive serial control signals transmitted by the management connector. The signal controller can be a CPLD (Complex Programmable Logic Device).

[0131] According to an embodiment of the present application, the power supply system also includes a power supply management expansion board disposed outside the first cabinet. By disposing the power supply management expansion board outside the first cabinet, space inside the first cabinet can be saved, thereby allowing for the installation of more power supply trays and improving the space utilization rate inside the cabinet. Furthermore, a plurality of signal lines and a signal controller are arranged within the power supply management expansion board. Status signals are transmitted to the signal controller via the signal lines for decoding. The signal controller can also decode the serial control signals sent down to restore the control signals compatible with the power supply tray. Thus, while the power supply tray is used to supply power to the independent server of the peripheral device, the operating status of multiple power supply trays can be closely monitored, thereby improving safety and controllability.

[0136] According to an embodiment of the present application, a third circuit board is disposed inside the power supply tray, and a third conductive path is arranged on the third circuit board. The third conductive path is used to transmit the target voltage to the first power supply clamping device group.

[0137] The first end of the third conductive path is electrically connected to the first power supply clamping assembly, and the second end of the third conductive path is electrically connected to the power supply unit. The number of third conductive paths can be determined based on the number of power supply units in a power supply tray. There is no limit on the number of third conductive paths.

[0139] The first power supply clamping component can be a first power supply wire clamp group, and the first power supply clamping device in the component can be a first power supply wire clamp, that is, the first power supply wire clamp group can include at least one first power supply wire clamp. When only one first power supply wire clamp is included, the multiple power supply units in the power supply tray are electrically connected to the first power supply wire clamp through a third conductive path. When only multiple first power supply wire clamps are included, the multiple power supply units in the power supply tray can be electrically connected to multiple first power supply wire clamps through multiple third conductive paths. There is no limit on the number of first power supply wire clamps in the first power supply wire clamp group.

[0141] The signal connector may be provided on an area of the first panel corresponding to the power supply tray.

[0142] According to an embodiment of the present application, the power supply tray further includes a plurality of input voltage terminal groups. The first ends of the plurality of input voltage terminal groups are electrically connected to the plurality of power supply units, and the second ends of the plurality of input voltage terminal groups are electrically connected to an input power source, for receiving an input voltage so that the plurality of power supply units process the input voltage to obtain a target voltage.

[0143] The number of the plurality of input voltage terminal groups is equal to the number of the power supply units. The plurality of input voltage terminal groups can be arranged at the front of the power supply tray.

[0144] According to an embodiment of the present application, the power supply tray includes a plurality of power supply units, a first power supply clamping assembly, a third circuit board, and a signal connector. A third conductive path is arranged on the third circuit board. The power supply tray also includes a plurality of input voltage terminal groups, which are arranged at the front of the power supply tray. Each power supply unit receives an input voltage through the plurality of input voltage terminal groups, and then performs AC / DC conversion and boost processing on the input voltage to obtain a target voltage, which is then transmitted to the first power supply clamping assembly through the third conductive path so as to converge onto the conductive row group. At the same time, each power supply unit generates a status signal based on the current operating status information, and transmits it to the signal connector through the signal path, so that the signal connector can forward the multiple status signals to the signal controller, thereby realizing the processing of the input voltage and real-time monitoring of the power supply unit.

[0150] like Figure 17As shown, the power supply system includes a first cabinet 101, multiple power trays 102, a management tray 203, an adapter tray 204, and multiple conductive bar groups 104. The management tray 203 and adapter tray 204 are arranged parallel to the multiple power trays 102, and the multiple conductive bar groups 104 are embedded in a first direction perpendicular to the backs of the multiple power trays 102, management tray 203, and adapter tray 204.

[0151] According to an embodiment of the present application, an electronic device may include a powered node, at least one electronic node, and a plurality of powered bank groups.

[0152] According to an embodiment of the present application, the peripheral power supply system in the electronic device may include the above-mentioned power supply system, and the electronic device may further include an independent second cabinet, in which a power receiving node, multiple power receiving row groups and at least one electronic node may be set.

[0153] According to an embodiment of the present application, a powered node and at least one electronic node are provided in the second cabinet. The electronic node includes but is not limited to: a computing node, a storage node or a switching node.

[0154] According to an embodiment of the present application, a powered node includes a first powered terminal group, a first end of the first powered terminal group is electrically connected to an external cable, and a second end of the first powered terminal group is electrically connected to a conductive path in a circuit board of the powered node, for receiving a target voltage transmitted by a peripheral power supply system through the external cable.

[0155] According to an embodiment of the present application, a plurality of power receiving bank groups are embedded in the power receiving node and the at least one electronic node along a second direction perpendicular to the back of the power receiving node and the at least one electronic node, and are used to electrically connect the at least one electronic node and the power receiving node so that the target voltage flows to the at least one electronic node.

[0156] The second direction may be a direction outside the second cabinet and perpendicular to the backs of the powered node and the at least one electronic node.

[0157] According to an embodiment of the present application, the powered node further includes a fourth circuit board and a second power supply clamping assembly.

[0158] According to an embodiment of the present application, a fourth circuit board is disposed inside the power receiving node, and a fourth conductive path is arranged on the fourth circuit board. The fourth conductive path is used to transmit the target voltage to the second power supply clamping assembly.

[0159] A first end of the fourth conductive path is electrically connected to the first power receiving terminal group, and a second end of the fourth conductive path is electrically connected to at least one second power supply clamping device in the second power supply clamping assembly. The number of fourth conductive paths can correspond to the number of second power supply clamping devices in the second power supply clamping assembly, and the number of fourth conductive paths is not limited.

[0160] According to an embodiment of the present application, one side of the second power supply clamping assembly is fixed on the fourth circuit board, and the other side of the second power supply clamping assembly is used to clamp multiple power receiving bus groups so that the target voltage is converged to multiple power receiving bus groups, and power is supplied to at least one electronic node through multiple power receiving bus groups.

[0161] The second power supply clamping assembly can be a second power supply clamp set, and the second power supply clamping device within the assembly can be a second power supply clamp. That is, the second power supply clamp set can include at least one second power supply clamp, and the number of second power supply clamps is not limited. The second cabinet (server cabinet) does not contain any device capable of autonomously supplying or generating power. The second cabinet (server cabinet) only passively receives the target current and target voltage transmitted by the power supply system.

[0162] According to an embodiment of the present application, the first power supply terminal and the second power supply terminal of the power supply system in the first cabinet can be electrically connected to the first power receiving terminal group in the second cabinet through an external cable.

[0163] According to an embodiment of the present application, an electronic device may include a first cabinet, in which a power supply system may be provided. The electronic device may also include a second cabinet, a power receiving node, multiple power receiving bus groups, and at least one electronic node, wherein the power receiving node includes a first power receiving terminal group, a fourth conductive path, and a second power supply clamping assembly. Because the server does not include any device capable of autonomously supplying or generating power, it only passively receives voltage or current through the power receiving node, thereby improving server security and enabling the installation of more electronic nodes in the second cabinet, thereby increasing space utilization within the second cabinet and the server's computing power.

[0164] Figure 18 A schematic diagram of a server according to an embodiment of the present application is shown.

[0165] like Figure 18 As shown, the server may include a second cabinet 1801, a power receiving node 1802, multiple power receiving bar groups 1803 and multiple server nodes 1804, that is, multiple electronic nodes, wherein the power receiving node 1802 includes a first power receiving terminal group 1805, and the first power receiving terminal group 1805 may be set at the back of the power receiving node 1802. It can be understood that Figure 18 The number of server nodes shown in is only an example, and the embodiments of the present application are not limited thereto.

[0166] According to an embodiment of the present application, since the first cabinet of the power supply system does not contain a server node, multiple power supply trays can be set in the first cabinet, and each power supply tray includes multiple power supply units to generate a target voltage that can meet high power requirements. Since there is no device in the server that can independently supply power or generate power, the voltage or current is passively received only through the power receiving node, which can improve the safety of the server and enable more electronic nodes to be set in the second cabinet of the server, thereby improving the space utilization in the second cabinet and the computing power of the server. Then, the target voltage is transmitted to the server through an external cable. After receiving the target voltage, the power receiving node of the server transmits the target voltage to at least one electronic node through multiple power receiving row groups to power the electronic node, thereby realizing the use of the power supply system to power the server so that the server works according to the current passively received.

Multiple power supply units 1501 in multiple power supply trays 102 in the power supply system within a first cabinet 101 perform AC / DC conversion and boost processing on the input voltage to obtain a target voltage. The target voltage is transmitted to the server within a second cabinet 1801 via an external cable 2101. After receiving the target voltage, multiple first power receiving terminals in a first power receiving terminal group 1805 in the server's power receiving node 1802 transmit the target voltage to multiple second power supply clamps in a second power supply clamp group via a fourth conductive path arranged on a fourth circuit board. The multiple second power supply clamps each clamp multiple power receiving bar groups 1803. The target voltage is transmitted via the multiple second power supply clamps to multiple power receiving bar groups 1803 embedded along the back perpendicular to the power receiving node and multiple server nodes 1804.

[0174] like Figure 22 As shown, the power supply method of this embodiment includes operations S2210 to S2230.

[0175] In operation S2210, in response to receiving an input voltage, multiple power supply units convert and boost the input voltage to obtain a target voltage. In operation S2220, the target voltage is aggregated to the management tray and adapter tray via multiple conductive banks. In operation S2230, the target voltage is transmitted to the server using the first and second power supply terminals in the management tray and adapter tray, so that the server's powered node receives the target voltage and transmits the target voltage to multiple server nodes.

[0176] According to an embodiment of the present application, after the first power receiving terminal group in the power receiving node of the server receives the target voltage through an external cable, the target voltage is transmitted to the second power supply clamping component through a fourth conductive path arranged on the fourth circuit board. The second power supply clamping component clamps multiple power receiving bus groups. The target voltage is transmitted to the multiple power receiving bus groups clamped by it through the second power supply clamping component, and the target voltage is transmitted to at least one electronic node through the multiple power receiving bus groups to power the at least one electronic node.

[0177] According to an embodiment of the present application, by inputting an input voltage to multiple power supply units and converting and boosting the input voltage using the multiple power supply units, a target voltage that meets high power requirements can be obtained. The target voltage is then aggregated to a management tray and an adapter tray using multiple conductive bus bars, which are then forwarded to the server via the management tray and the adapter tray. Upon receiving the target voltage, the server's power receiving node can distribute the target voltage to at least one electronic node via the power receiving bus bar, thereby converting the input voltage into a high DC voltage suitable for normal server operation and increasing the output power, so that the power provided by the power supply system can meet the power requirements of multiple high-computing-power server modules.
