[0001] The present application relates to the technical field of power supply, and particularly to a power supply system and an electronic device. Background Art

[0002] A whole cabinet server is a cabinet device integrated with computing nodes and a power supply device for supplying power to the computing nodes. With the development of technology, the current computing power demand for computing nodes is increasing day by day, so that computing nodes composed of more servers are required to meet the higher computing power demand. However, with the increasing computing power demand of computing nodes, the power demand required by the computing nodes is also getting higher and higher. Summary of the Invention

[0003] In view of the above problems, the present application provides a power supply system and an electronic device.

[0004] According to a first aspect of the present application, there is provided a power supply system including: a plurality of power supply trays for respectively converting and boosting a plurality of input voltages to obtain a target voltage and outputting the target voltage to a power supply transfer tray; a power supply transfer tray including a plurality of power supply terminals, a first end of each of the plurality of power supply terminals being electrically connected to a conduction path in a circuit board of the power supply transfer tray, and a second end of each of the plurality of power supply terminals being used for electrically connecting to an external wiring cable to transmit the target voltage in the conduction path to the plurality of power supply terminals, so as to transmit the target voltage to a peripheral load through the external wiring cable; and a plurality of conductive busbar groups embedded in the plurality of power supply trays and the power supply transfer tray along a first direction perpendicular to the backs of the plurality of power supply trays and the power supply transfer tray for electrically connecting the plurality of power supply trays and the power supply transfer tray, so that the target voltages generated by the plurality of power supply trays converge to the power supply transfer tray through the plurality of conductive busbar groups.

[0005] A second aspect of the present application provides an electronic device including: a power receiving node including a first power receiving terminal group, a first end of the first power receiving terminal group being electrically connected to an external wiring cable, and a second end of the first power receiving terminal group being electrically connected to a conduction path in a circuit board of the power receiving node, for receiving the target voltage transmitted by a power supply system of a peripheral device through the external wiring cable and transmitting the target voltage to a plurality of server nodes; and a plurality of power receiving busbar groups embedded in the power receiving node and at least one electronic node along a second direction perpendicular to the backs of the power receiving node and the at least one electronic node for electrically connecting the at least one electronic node and the power receiving node, so that the target voltage is transmitted to the at least one electronic node.

[0006] 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 busbar groups. The power supply transfer tray includes a plurality of power supply terminals, and the power supply system does not contain server nodes. A plurality of power supply trays and a power supply transfer tray are arranged in a first cabinet of the power supply system. The plurality of conductive busbar groups are embedded in the plurality of power supply trays and the power supply transfer tray along a first direction perpendicular to the backs of the plurality of power supply trays and the power supply transfer tray. Thus, without server nodes in the first cabinet, the space within the power supply system is greatly saved. Furthermore, a plurality of power supply trays can be arranged in the first cabinet to generate a target voltage that can meet high-power requirements and a target current corresponding to the target voltage.

[0007] According to an embodiment of the present application, an external power supply may input a plurality of input voltages to the plurality of power supply trays simultaneously. The plurality of power supply trays perform AC-to-DC conversion processing and boost processing on the plurality of input voltages to obtain a target voltage, thereby realizing the processing of the input voltages so that the input voltages can be converted into a DC high voltage suitable for the normal operation of servers and can also meet the power requirements of a plurality of high-computing-power server modules.

[0008] According to an embodiment of the present application, after the plurality of power supply trays generate the target voltage, they transmit it to the plurality of conductive busbar groups. The plurality of conductive busbar groups electrically connect the plurality of power supply trays and the power supply transfer tray, enabling the target voltage to converge to the power supply transfer tray through the plurality of conductive busbar groups, thereby realizing the transfer of the target voltage. In addition, by setting a plurality of conductive busbar groups, the plurality of conductive busbar groups can jointly share the target current corresponding to the target voltage, reducing the current flowing through each conductive busbar group and the current in the contact area between each conductive busbar group and the power supply transfer tray and the plurality of power supply trays. Thus, the current loss and load of each conductive busbar group can be reduced, avoiding the temperature rise in local areas of the power supply system caused by high load and high current loss. Furthermore, conductive busbar groups with a smaller cross-sectional area can be used, reducing the volume of the power supply system and improving the safety and space utilization rate of the power supply system.

[0009] According to an embodiment of the present application, after receiving the target voltage converged by the plurality of conductive busbar groups, the power supply transfer 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 a high power matching the high computing power.

[0033] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present application. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a thorough understanding of the embodiments of the present application. However, it is obvious that one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present application.

[0034] The terms used herein are merely for describing specific embodiments and are not intended to limit the present application. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0035] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0036] In the case of using expressions such as "at least one of A, B, and C", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C).

[0037] A full rack server is a cabinet device integrated with multiple server nodes and a power supply device for powering multiple server nodes. With the development of technology, the current computing power demand for server nodes is increasing day by day, so server nodes composed of more servers are needed to meet the higher computing power demand. However, as the computing power demand of server nodes increases day by day, the power demand required by server nodes is also getting higher and higher.

[0038] Embodiments of the present application provide a power supply system, including: a plurality of power supply trays for respectively converting and boosting multiple input voltages to obtain a target voltage and outputting it to a power supply transfer tray; the power supply transfer tray includes a plurality of power supply terminals, the first ends of the plurality of power supply terminals are electrically connected to a conduction path in the circuit board of the power supply transfer tray, and the second ends of the plurality of power supply terminals are used to be electrically connected to an external wiring cable to transmit the target voltage in the conduction path to the plurality of power supply terminals, so as to transmit the target voltage to a peripheral load through the external wiring cable; a plurality of conductive busbar groups are embedded in the plurality of power supply trays and the power supply transfer tray along a first direction perpendicular to the backs of the plurality of power supply trays and the power supply transfer tray for electrically connecting the plurality of power supply trays and the power supply transfer tray, so that the target voltages generated by the plurality of power supply trays converge to the power supply transfer tray through the plurality of conductive busbar groups.

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

[0040] In some embodiments, also because the computing power of the server is getting higher and higher and the power consumption is also getting larger, the requirement for the power of the power supply of the full rack is also getting higher and higher. The core component in the power supply device is the power supply unit, which can convert alternating current into direct current required by the server. Due to the size limitation of the full rack, the number of power supply units that can be accommodated in the power supply device inside the full rack is small, so the power is too low to meet the power requirements of the server. And as the server power increases, at a certain power, due to the relatively low voltage of 54V DC power supply, the current flowing through the copper busbar is getting larger and larger, resulting in a sharp increase in the current loss on the copper busbar.

[0041] According to the embodiments of the present application, the power supply system may include a plurality of power supply trays, a power supply transfer tray, and a plurality of conductive busbar 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, in which a plurality of power supply trays and power supply transfer trays may be provided. No server nodes are provided in the first cabinet of the power supply system.

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

[0044] The input voltage may be alternating current. It is necessary to use the relevant power supply structure in the power supply tray to convert the alternating current into direct current and boost it to obtain the target voltage and the 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 requirements of the server. For example, the input voltage may be 220V alternating current. After being converted and boosted by a plurality of power supply trays, a target voltage of 440V direct current 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, thereby improving the space utilization rate in the first cabinet of the power supply system.

[0045] According to an embodiment of the present application, the power supply tray includes a plurality of power supply terminals. The first ends of the plurality of power supply terminals are electrically connected to the conduction paths in the circuit board of the power supply transfer tray, and the second ends of the plurality of power supply terminals are used to be electrically connected to the external wiring cable to transmit the target voltage in the conduction path to the plurality of power supply terminals, so as to transmit the target voltage to the peripheral load through the external wiring cable.

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

[0047] According to an embodiment of the present application, a plurality of conductive busbar groups are embedded in the plurality of power supply trays and power supply transfer trays along a first direction perpendicular to the backs of the plurality of power supply trays and power supply transfer trays, for electrically connecting the plurality of power supply trays and power supply transfer trays, so that the target voltage generated by the plurality of power supply trays converges to the power supply transfer tray through the plurality of conductive busbar 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 power supply transfer trays. 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 busbar groups, the multiple power supply trays and the power supply transfer tray can be interconnected through the multiple conductive busbar 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 the server independent of the power supply system. Further, by connecting the multiple power supply trays and the power supply transfer tray with multiple conductive busbar groups, the multiple conductive busbar groups can jointly share the target current, reduce the current flowing through each conductive busbar group, thereby reducing the current loss, load and cross-sectional area of each conductive busbar group. At the same time, the current in the contact area between each conductive busbar group and the power supply transfer tray and the multiple power supply trays can also be reduced, preventing the temperature from rising due to excessive current and damaging the power supply system.

[0050] According to an embodiment of the present application, the power supply system may include multiple power supply trays, a power supply transfer tray and multiple conductive busbar groups. The power supply transfer tray includes multiple power supply terminals, and the power supply system does not contain server nodes. Multiple power supply trays and a power supply transfer tray are arranged in the first cabinet of the power supply system, and multiple conductive busbar 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, so that without server nodes in the first cabinet, the space in the power supply system is greatly saved. Furthermore, multiple power supply trays can be arranged in the first cabinet to generate a target voltage that can meet the high-power demand and the 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 the multiple power supply trays. The multiple power supply trays perform AC-DC conversion processing and boost processing on the multiple input voltages to obtain a target voltage, thereby realizing the processing of the input voltage so that the input voltage can be converted into a DC high voltage suitable for the normal operation of the server and can also meet the power requirements of multiple high-computing power server modules.

[0052] According to an embodiment of the present application, after the multiple power supply trays generate the target voltage, it is transmitted to the multiple conductive busbar groups. The multiple conductive busbar groups electrically connect the multiple 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 multiple conductive busbar groups, thereby realizing the transfer of the target voltage. In addition, by setting multiple conductive busbar groups, the multiple conductive busbar groups can jointly share the target current corresponding to the target voltage, reduce the current flowing through each conductive busbar group and the current in the contact area between each conductive busbar group and the power supply transfer tray and the multiple power supply trays, thereby reducing the current loss and load of each conductive busbar group, avoiding the temperature rise in the local area of the power supply system caused by high load and high current loss, and further enabling the use of conductive busbar groups with a smaller cross-sectional area, reducing the volume of the power supply system, and improving the safety and space utilization rate of the power supply system.

[0053] According to an embodiment of the present application, after receiving the target voltage converged by multiple conductive row groups, the power supply transfer 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 matching high computing power.

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

[0055] As Figure 1 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. 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 multiple conductive row groups may include at least one first conductive row group and at least one second conductive row 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 may be disposed in a first area on the backs of the multiple power supply trays and the management tray, for electrically connecting a part of the multiple power supply trays to the management tray, so that the target voltage generated by a part of the power supply trays converges to the management tray.

[0058] The first area may be characterized as an area on the backs of the management tray and a part of the power supply trays. At least one first conductive row group needs to be electrically connected to the management tray and a part of the power supply trays. At least one first conductive row group may converge the target voltage generated by the 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 may be disposed in a second area on the backs of the multiple power supply trays and the transfer tray, for electrically connecting another part of the multiple power supply trays to the transfer tray, so that the target voltage generated by another part of the power supply trays converges to the transfer tray, wherein the first area and the second area do not overlap.

[0060] The second region can be characterized as the region on the back of the transfer tray and another part of the power supply tray. At least one second conductive busbar group needs to be electrically connected to the transfer tray and another part of the power supply tray. At least one second conductive busbar group can converge the target voltage generated by multiple power supply trays in the second region to the transfer tray. The first conductive busbar group and the second conductive busbar group are not connected to each other. The number of the first conductive busbar groups in the first region and the number of the second conductive busbar groups in the second region are not limited herein.

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

[0062] P = I²R (1);

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

[0064] P1 = [(1 / 2)I]²R (2);

[0065] Wherein, P1 can be characterized as the first loss value.

[0066] Thus, after sharing the load by multiple conductive busbar groups, the load, heat generation and loss of each conductive busbar group can be reduced. Furthermore, even when high-voltage DC is adopted, for example, 400V DC, the current on each conductive busbar group can be effectively reduced. Therefore, the first conductive busbar group and the second conductive busbar group with smaller cross-sectional areas can be adopted.

[0067] According to the embodiments of the present application, multiple conductive busbar groups include at least one first conductive busbar group and at least one second conductive busbar group. The first conductive busbar group and the second conductive busbar group are respectively arranged in different regions and electrically connect different power supply trays to the management tray or the transfer tray. Thus, under the joint action of multiple conductive busbar groups, the target voltage can be efficiently transmitted to the management tray and the transfer tray, and the current flowing through each conductive busbar group, the current in the contact area between each conductive busbar group and the power supply transfer tray and multiple power supply trays, and the cross-sectional area of the conductive busbar group can be reduced. Also, due to the reduction of the cross-sectional area of the conductive busbar group, more first conductive busbar groups and second conductive busbar groups can be arranged on the limited first panel, improving the space utilization rate.

[0068] Figure 2 The schematic diagram of multiple conductive busbar groups in the power supply system according to the embodiments of the present application is shown.

[0069] AsFigure 2 As shown, a plurality of 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 region 205, and the two second conductive bar groups 202 are both located in the second region 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 part of the power supply tray, and the two second conductive bar groups 202 electrically connect the transfer tray 204 and another part of the power supply tray. It can be understood that Figure 2 The number of conductive bar groups shown 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 arranged on the upper side of a plurality of power supply trays in a direction parallel to the plurality of power supply trays, for managing and monitoring the target voltage output by the plurality of power supply trays, and outputting the target voltage generated by a part of the power supply trays to the peripheral load.

[0071] According to an embodiment of the present application, the transfer tray can be arranged on the lower side of a plurality of power supply trays in a direction parallel to the plurality of power supply trays, for outputting the target voltage generated by another part of the power supply trays to the peripheral load.

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

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

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

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

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

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

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

[0079] According to an embodiment of the present application, the first power supply terminal is disposed 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 wiring cable, and is used to receive the target voltage in the first conductive path and be electrically connected to the peripheral load through the external wiring cable to transmit the target voltage to the peripheral 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 the serial status signals corresponding to a plurality of power supply trays to the management controller.

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

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

[0084] The management connector and the management controller may be connected through a signal path in the circuit board, and the serial status signals may be transmitted to the management controller through the signal path. Wherein, the management controller may be a related controller such as BMC (Baseboard Management Controller, embedded controller). When the management controller receives the serial status signals forwarded by the management connector, the management controller performs signal parsing on the serial status signals to obtain the plurality of power supply status information of the plurality of power supply trays. The power supply status information may include the current operating status of the power supply tray, the generated target voltage, the target current generated at the target voltage, the closing or turning off of the switch, the operating temperature, the ID (Identification) of the power supply tray, and other status information.

[0085] After parsing and obtaining multiple power supply status information, the management controller can selectively send the power supply status information to the interactive network port according to the power supply status information for reporting to an external switching device. For example, it is preset to send the abnormal power supply status information to the interactive network port so that the external switching device can make decisions based on the received abnormal power supply status information. The normal power supply status information can be controlled and decided by the management controller. After parsing and obtaining multiple power supply status information, the management controller can also send all the multiple power supply status information to the interactive network port for reporting to the external switching device, and all are for the external switching device to make decisions and controls.

[0086] The interactive network port and the management controller can be connected through a signal path. After receiving multiple power supply status information, the external switching device can make decisions on the corresponding power supply trays and send multiple decision signals to the interactive network port. The multiple decision signals are transmitted to the management controller via the signal path. The management controller processes the multiple decision signals to generate multiple serial decision signals, and then forwards them to the corresponding power supply trays through the management connector.

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

[0088] The management controller can classify the power supply status information. When receiving the serial status signal, it parses and obtains multiple power supply status information, and judges and manages each power supply status information according to a preset three-level classification. When it is confirmed that the power supply status information is of 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 of the second level, the power supply status information is sent to the interactive network port for reporting to the external switching device, waiting for the decision signal sent by the external switching device, and a serial control signal is jointly generated according to the decision signal and the power supply status information. When it is confirmed that the power supply status information is of the first level, while generating a first serial control signal according to the power supply status information, the power supply status information is sent to the interactive network port, waiting for the decision signal sent by the external switching device, and a second serial control signal is jointly generated according to the decision signal and the power supply status information.

[0089] For example, according to the power supply status information, a three-level classification is preset. The first level is that the target voltage < 220V, the target current < 1A, and the operating temperature > 65°. The second level is that 220V ≤ target voltage ≤ 350V, 1A ≤ target current ≤ 10A, and 45° ≤ operating temperature ≤ 65°. The third level is that the target voltage > 350V, the target current > 10A, and the operating temperature < 45°. The management controller parses the serial status signals respectively to obtain 3 power supply status information. The first power supply status information includes the first power supply tray, the target voltage is 400V, the target current is 16A, and the operating temperature is 44°. The second power supply status information includes the second power supply tray, the target voltage is 10V, the target current is 0.1A, and the operating temperature is 70°. The third power supply status information includes the third power supply tray, the target voltage is 600V, the target current is 20A, and the operating temperature is 55°. When any condition in the power supply status information meets a certain level, it is determined that the power supply status information belongs to that level. Thus, according to the 3 power supply status information, it is determined that the first power supply status information meets the third level, the second power supply status information meets the first level, and the third power supply status information meets the second level.

[0090] According to the level of each determined power supply status information, the management controller generates a serial control signal to continue the running state according to the first power supply status information and sends it to the first power supply tray. A serial control signal to pause the running state is generated according to the second power supply status information and sent to the second power supply tray. At the same time, the second power supply status information is sent to the interactive network port to wait for the decision of the external switching device. The external switching device sends a decision signal to stop processing the input voltage and turn on all the fans of the power supply tray to the management controller. The management controller sends a second serial control signal to stop processing the input voltage and turn on all the fans of the power supply tray to the second power supply tray according to the decision signal and the second power supply status information. The third power supply status information is sent to the interactive network port to wait for the decision of the external switching device. The external switching device sends a decision signal to stop running and wait for maintenance to the management controller. The management controller sends a serial control signal to stop running and wait for maintenance to the third power supply tray according to the decision signal and the third power supply status information.

[0091] According to an embodiment of the present application, the management tray includes a first power-receiving clamping assembly, a first circuit board, a first power supply terminal, a management connector, and a management controller. The first power-receiving clamping assembly clamps at least one first conductive busbar group, so that a first conduction path is electrically connected to the at least one first conductive busbar group. The first conductive busbar group transmits a target voltage obtained by converging from a part of the power supply tray to the first power supply terminal via the first conduction path. The first power supply terminal is electrically connected to an independent server through an external cable, so that the target voltage can be transmitted to the server, enabling the server to perform normal business operations and other processes when meeting high-power requirements.

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

[0105] As Figure 6 shown, a second power receiving wire clamp group 601, a second circuit board 602, and a second power supply terminal 603 can be arranged in the adapter tray 204. Among them, a second conduction path 6021 is arranged in the second circuit board 602. The second power receiving wire clamp group 601 includes two second power receiving wire clamps, and the two second power receiving wire clamps can be electrically connected to the second power supply terminal 603 through the second conduction path 6021. It can be understood that Figure 6 the number of the second power supply terminals shown is only an example, and the embodiments of the present application are not limited thereto.

[0106] Figure 7 Fig. shows a side view of the internal structure of the adapter tray according to an embodiment of the present application.

[0107] As Figure 7 shown, the management tray 204 includes two second power receiving wire clamps 6011 and a second power supply terminal 603. The power receiving wire clamp and the second power supply terminal are electrically connected through the second conduction path 6021.

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

[0109] According to an embodiment of the present application, a plurality of conductive busbar group slots adapted to the plurality of conductive busbar groups are arranged on the back of the plurality of power supply trays, management trays, and adapter trays. When the plurality of conductive busbar groups are inserted into the plurality of conductive busbar group slots, the plurality of conductive busbar groups are clamped by the first power receiving clamping device group or the second power receiving clamping device group and are electrically connected to the management tray, the adapter tray, and the plurality of power supply trays.

[0110] Figure 8 Fig. shows a schematic diagram of the plurality of conductive busbar group slots according to an embodiment of the present application.

[0111] As Figure 8 shown, a plurality of conductive busbar group grooves 801 are arranged in the first area and the second area on the backs 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 busbar group positioning pins are arranged in the conductive busbar group slot. The plurality of retractable conductive busbar group positioning pins are respectively arranged at the corners of the conductive busbar group slot, and the distance from the bottom of the conductive busbar group slot is a predetermined depth, and are used to abut against the positioning slots of the conductive busbar group when the conductive busbar group is inserted into the conductive busbar group slot, so that the conductive busbar group is inserted into the conductive busbar group slot at a predetermined depth and is clamped by the first power receiving clamping device group or the second power receiving clamping device group.

[0113] Positioning slots can be respectively arranged at predetermined positions at the corners of the conductive busbar group, so that after the conductive busbar group is inserted into the conductive busbar group slot, the retractable conductive busbar group positioning pins can be stuck in the positioning slots of the conductive busbar group, thereby fixing the conductive busbar group and keeping it inserted at a predetermined depth. The retractable conductive busbar group positioning pins of the conductive busbar group slot can be screw-shaped retractable positioning pins, or can be right-angled retractable positioning pins. The shape of the retractable conductive busbar group positioning pins is not limited herein.

[0114] According to an embodiment of the present application, a plurality of conductive busbar group slots respectively adapted to a plurality of conductive busbar groups are arranged on the backs of the plurality of power supply trays, management trays and adapter trays. Each conductive busbar group slot can be provided with a plurality of retractable conductive busbar group positioning pins. The plurality of retractable conductive busbar group positioning pins are respectively arranged at the corners of the conductive busbar group slot, and the distance from the bottom of the conductive busbar group slot is a predetermined depth. When the conductive busbar group is inserted into the conductive busbar group groove, the conductive busbar group can be clamped at a predetermined depth by the plurality of retractable conductive busbar group positioning pins, so that the conductive busbar group can be stably and firmly stuck in the conductive busbar group groove, avoiding the problem that it cannot be clamped by the first power receiving clamping device group or the second power receiving clamping device group caused by tolerance problems due to a short size, improving the design stability of the conductive busbar group, and reducing problems such as virtual insertion of the conductive busbar group caused by tolerance problems of the conductive busbar group.

[0115] Figure 9 The schematic diagram of the internal structure of the conductive busbar group slot of the adapter tray according to the embodiment of the present application is shown.

[0116] As Figure 9 shown, a plurality of retractable conductive busbar group positioning pins 901 can be arranged at the corners in the conductive busbar group slot 801.

[0117] Due to the tolerance problem of the busbar group, even when the busbar group is inserted into the busbar group slot, it may not be clamped by the first power receiving clamping device or the second power receiving clamping device. Therefore, a clamping device elastic structure can be provided in the first power receiving clamping device and the second power receiving clamping device, and an adjustable clamping plate can be provided in the first power receiving clamping device or the second power receiving clamping device. When the copper busbar cannot be clamped due to tolerance problems, the copper busbar can be abutted against the clamping device elastic structure through the clamping device elastic structure. An adjustable clamping plate can also be provided on the clamping device elastic structure. 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 provided 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 a clamping device elastic structure and an adjustable conductive plate into the clamping device (line clamp) and combining multiple telescopic busbar group positioning pins in the busbar group slot, multiple insurances can be provided for the insertion and clamping of the busbar group, thereby greatly reducing the risk of loose clamping of the busbar group caused by tolerance problems and improving the reliability of the power receiving clamping device and the busbar group slot.

[0118] Figure 10 The schematic diagram of the power receiving clamping device according to an embodiment of the present application is shown.

[0119] As Figure 10 shown, the power receiving clamping device can include a first clamping plate 1001 and a second clamping plate 1002. The tightness of the power receiving clamping device can be controlled by two first adjustable screws 1003 between the first clamping plate 1001 and the second clamping plate 1002. The clamping device elastic structure 1004 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 clamping device elastic structure 1004, and then the two clamping plates will clamp the clamping device elastic structure tightly.

[0120] Figure 11 The schematic diagram of the power receiving clamping device according to another embodiment of the present application is shown.

[0121] As 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 is fixed on the clamping device elastic structure 1004. The adjustable clamping plate may include a telescopic spiral structure 1101 and a copper bar clamping device 1102. When a copper bar with a tolerance problem is inserted into the copper bar slot, due to the insufficient depth of the copper bar and the limited length of the original clamping device elastic structure 1004, the telescopic spiral structure 1101 can be adjusted to increase the length of the copper bar clamping device, so that the copper bar clamping device 1102 can abut against the copper bar. Then, the two first adjustable screws 1003 between the first clamping plate 1001 and the second clamping plate 1002 are tightened, so that the whole power receiving clamping device and the copper bar are more stable and firm.

[0122] Figure 12 FIG. shows a schematic diagram of a power receiving clamping device according to another embodiment of the present application.

[0123] As Figure 12 shown, the power receiving clamping device may further include only adjustable clamping plates. The two adjustable clamping plates are arranged at the bottoms of the two clamping plates of the clamping device. The distance between the copper bar clamping device 1102 and the bottom of the clamping plate is adjusted by the second adjustable screw 1201. The copper bar clamping device 1102 is fixed on the connecting plate 1202. When a copper bar with a tolerance problem is inserted into the copper bar slot, due to the insufficient depth of the copper bar, the second adjustable screw 1201 can be adjusted to make the copper bar clamping device 1102 close 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 arranged outside the plurality of power supply trays and the power supply transfer trays along a first direction perpendicular to the backs of the plurality of power supply trays and the power supply transfer trays, and is used for transmitting 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 according to the working operation status, internal temperature and other statuses, and transmit the status signal to the management tray.

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

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

[0128] According to an embodiment of the present application, a signal controller is provided inside the power supply management expansion board. The signal controller is configured to respond to receiving a plurality of status signals, perform decoding processing on the plurality of status signals to obtain a serial status signal that meets the reserved protocol format, and transmit it to the management connector.

[0129] According to an embodiment of the present application, the signal controller is further configured to respond to receiving a serial control signal generated by the management controller, perform encoding processing on the serial control signal to obtain a plurality of control signals, so that a plurality of power supply trays switch their power supply states under the control of the plurality of control signals.

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

[0131] According to an embodiment of the present application, the power supply system further includes a power supply management expansion board disposed outside the first cabinet. By disposing the power supply management expansion board outside the first cabinet, the space inside the first cabinet can be saved, so that more power supply trays can be provided, improving the space utilization rate inside the cabinet. Further, a plurality of signal lines and a signal controller are arranged inside the power supply management expansion board. The status signals are transmitted to the signal controller through the signal lines for decoding, and the signal controller can also decode the issued serial control signal to restore the control signal adapted to the power supply tray. Thus, while the power supply tray supplies power to the independent server of the peripheral device, the operating states of a plurality of power supply trays can be closely monitored, improving safety and controllability.

A third conduction path is arranged on the third circuit board. The power supply tray further includes multiple input voltage terminal groups, which are arranged at the front part of the power supply tray. Each power supply unit receives an input voltage through the multiple input voltage terminal groups, and then performs AC-DC conversion and boost processing on the input voltage to obtain a target voltage, so as to transmit the target voltage to the first power supply clamping assembly through the third conduction path for convergence to the conductive busbar group. At the same time, each power supply unit generates a status signal according to the current operation status information and transmits the status signal to the signal connector through a signal path, so that the signal connector can forward the multiple status signals to the signal controller, realizing the processing of the input voltage and the real-time monitoring of the power supply unit.

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

[0152] According to an embodiment of the present application, the peripheral power supply system in the electronic device may include the above power supply system.

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

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

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

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

[0159] The first end of the fourth conductive path is electrically connected to the first power receiving terminal group, and the 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 the fourth conductive paths may correspond to the number of the second power supply clamping devices in the second power supply clamping assembly, and the number of the fourth conductive paths is not limited herein.

[0161] The second power supply clamping assembly may be a second power supply clip group, and the second power supply clamping device in the assembly may be a second power supply clip, that is, the second power supply clip group may include at least one second power supply clip, and the number of the second power supply clips is not limited herein. The second cabinet (server cabinet) does not contain any device that can supply power autonomously or generate power, and the second cabinet (server cabinet) only passively receives the target current and target voltage sent 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.

The electronic device may further include a second cabinet, a power receiving node, a plurality of power receiving row groups, and at least one electronic node. Among them, the power receiving node includes a first power receiving terminal group, a fourth conductive path, and a second power supply clamping assembly. Since no device that can supply power autonomously or generate power is provided in the server, the server only passively receives voltage or current through the power receiving node, thereby improving the safety of the server and enabling more electronic nodes to be provided in the second cabinet, improving the space utilization rate in the second cabinet and the computing power of the server.

It can be understood that Figure 18 the number of server nodes shown is only an example, and the embodiment of the present application is not limited thereto.

[0166] According to an embodiment of the present application, since the first cabinet of the power supply system does not contain server nodes, a plurality of power supply trays can be arranged in the first cabinet, and each power supply tray includes a plurality of power supply units, so as to generate a target voltage that can meet high-power requirements.

Then, through the external wiring cable, the target voltage is transmitted to the server. After receiving the target voltage, the power receiving node of the server transmits the target voltage to at least one electronic node through a plurality of power receiving row groups to supply power to the electronic node, realizing power supply by using the power supply system so that the server operates according to the passively received current.

[0172] As Figure 21As shown, the electronic device includes a power supply system and a server. Multiple power supply units 1501 in multiple power supply trays 102 of the power supply system in the first cabinet 101 are used to perform AC-DC conversion and boost processing on the input voltage to obtain a target voltage. Through the external connection cable 2101, the target voltage is transmitted to the server in the second cabinet 1801. After receiving the target voltage, multiple first power receiving terminals in the first power receiving terminal group 1805 of the power receiving node 1802 of the server transmit the target voltage to multiple second power supply clips in the second power supply clip group respectively through the fourth conduction path arranged on the fourth circuit board. Multiple second power supply clips respectively clamp multiple power receiving row groups 1803, and the target voltage is transmitted to multiple power receiving row groups 1803 embedded along the back perpendicular to the power receiving node and multiple server nodes 1804 through the multiple second power supply clips.

In operation S2220, the target voltage is converged to the management tray and the transfer tray through multiple conductive row groups. In operation S2230, the target voltage is transmitted to the server by using the first power supply terminal and the second power supply terminal in the management tray and the transfer tray, so that the power receiving node of the server 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 the external connection cable, the target voltage is transmitted to the second power supply clamping component respectively through the fourth conduction path arranged on the fourth circuit board.
