[0018] Figures 1 to 5In one embodiment of the power supply system of this application, the power supply system 1 includes a cabinet 9 and at least one power rack 2. The cabinet 9 includes a cabinet body 91 and a cabinet bus 3. The cabinet body 91 includes a plurality of housings 90, which can be configured to be of the same or different sizes and are stacked along the vertical direction of the cabinet body 91 (i.e., the Z-axis direction in the drawing). For example, the housings 90 can be configured to be the height of 1 to N rack units (RU) or open units (OCP OpenU, OU), hereinafter referred to as 1U, 2U...NU (N is a positive integer). In this embodiment, the power rack 2 is 1U in height and is configured to be detachably housed in any of the 1U housings 90 and is docked with the cabinet bus 3 along a docking direction (i.e., the X-axis direction). For ease of explanation, this application only describes a single housing 90 corresponding to the housing of a 1U power rack 2, and does not limit this application. For example, rack 9 can house one or more 1U or NU power supply racks, backup battery unit racks (BBU racks), server racks, power distribution unit racks, other power supply racks, and / or other load racks. In this embodiment, rack bus 3 is located adjacent to the rear edge of rack 91, extending vertically (i.e., along the Z-axis), and adjacent to multiple housings 90. Rack bus 3 includes a main body 31 and a pair of branch members 32 and 33. The main body 31 extends vertically (i.e., along the Z-axis) to form a first plug-in interface. The pair of branch members 32 and 33 are symmetrical to each other, respectively located on two opposite sides of the main body 31, and respectively form a second plug-in interface and a third plug-in interface. In this embodiment, at least one power supply rack 2 includes a housing 20, a first input bus 21, a second input bus 22, and multiple connectors 23, 24, and 25. The housing 20 includes a rack connection side 201, a receiving space 202, and a mounting space 204. A first input bus 21 and a second input bus 22 are housed in the receiving space 202. Multiple connectors 23, 24, and 25 are disposed on the rack connection side 201 of the housing 20 and are spaced apart along the direction extending from the rack connection side 201 (i.e., the Y-axis direction in the drawing). In this embodiment, each of the multiple connectors 23, 24, and 25 includes two connection terminals, which can be electrically connected to the first input bus 21 and / or the second input bus 22, respectively. In other embodiments, the connectors 23, 24, and 25 may each include one or more connection terminals depending on the polarity and / or potential configuration of the first input bus 21 and / or the second input bus 22.In this embodiment, the plurality of connectors includes at least a first connector 23 and a pair of second connectors 24 and 25, which are respectively disposed on both sides of the first connector 23. In other embodiments, the plurality of connectors may include a first connector 23 and one or more second connectors, which may be disposed on the same side or different sides of the first connector 23. The first connector 23 is configured to mate with the first plug-in interface (i.e., the body 31) of the rack bus 3 along the mating direction (i.e., the X-axis direction in the figure). The pair of second connectors 24 and 25 on the left and right of the first connector 23 are configured to mate with the second plug-in interface and the third plug-in interface (i.e., the pair of branch members 32 and 33) of the rack bus 3 along the mating direction (i.e., the X-axis direction). In this embodiment, the vertical direction of the rack bus 3 is perpendicular to the mating direction of each connector 23, 24, and 25. The mounting space 204 of the power rack 2 is used to accommodate one or more power supplies (PSUs), for example: Figure 3 The installation space 204 contains six power supply units (PSUs). In other embodiments, the installation space 204 may also accommodate one or more power supply units, and one or more supercapacitor units, backup battery units, other power supply units, and / or other load units. In this embodiment, the power output terminals of the power supply units (PSUs) are connected to the first input bus 21 and the second input bus 22 to supply power to the rack bus 3 via the first input bus 21, the second input bus 22, and connectors 23, 24, and 25. The first input bus 21 and the second input bus 22 may be configured to connect to different polarities or potentials, for example, the first input bus 21 and the second input bus 22 may be used to connect to suitable combinations of polarities or potentials such as (positive potential, negative potential), (positive potential, ground potential), (ground potential, positive potential), (ground potential, negative potential), (negative potential, positive potential), and (negative potential, ground potential).

[0019] In this embodiment, the first connector 23 and the second connectors 24 and 25 have the same or similar structures, but the two connection terminals of each connector can be configured with the same or different wiring variations. In this embodiment, the two connection terminals of the first connector 23 are electrically connected to the first input bus 21 and the second input bus 22, respectively, and the two connection terminals of the left second connector 24 are simultaneously connected to the first input bus 21, while the two connection terminals of the right second connector 25 are simultaneously connected to the second input bus 22. Thus, the left side of the first connector 23 can be designated as the first output terminal area, and the right side of the first connector 23 can be designated as the second output terminal area, and the pair of second connectors 24 and 25 have opposite polarities.

[0020] In this embodiment, the main body 31 of the cabinet bus 3 includes a first output bus 311, an insulating member 313, and a second output bus 312, extending in a vertical direction (i.e., the Z-axis direction). The insulating member 313 is located between the first output bus 311 and the second output bus 312, and together they form a first plug-in interface. The pair of branch members 32 and 33 are respectively connected to the first output bus 311 and the second output bus 312. In this embodiment, the branch members 32 and 33 have similar structures and are symmetrically arranged. The left branch member 32 is fixed to the outer wall of the first output bus 311 by a fastener 34, and the right branch member 33 is fixed to the outer wall of the second output bus 312 by a fastener 34. In other words, when the main body 31 is composed of the first output bus 311 and the second output bus 312 forming the first plug-in interface, the branch members 32 and 33 on both sides are fixed to the first output bus 311 and the second output bus 312 by fasteners 34, respectively, forming a second plug-in interface and a third plug-in interface of opposite polarities. Thus, when the three sets of output terminals of the power supply rack 2, namely the first connector 23 and the second connectors 24 and 25, are simultaneously connected to the branched rack bus 3, the current withstand value can be tripled, thereby providing greater current output and output power. The first output bus 311 and the second output bus 312 can be configured to connect to different polarities or potentials. For example, the first output bus 311 and the second output bus 312 can be used to connect to suitable combinations of polarities or potentials such as (positive potential, negative potential), (positive potential, ground potential), (ground potential, positive potential), (ground potential, negative potential), (negative potential, positive potential), and (negative potential, ground potential).

[0021] In this embodiment, the cabinet bus 3 further includes a housing 35 corresponding to the main body 31 and branch members 32 and 33, at least partially covering the main body 31 and branch members 32 and 33, and allowing the first plug-in interface formed by the main body 31 to mate with the first connector 23, and allowing the second plug-in interfaces and third plug-in interfaces formed by the branch members 32 and 33 to mate with the second connectors 24 and 25 respectively along the mating direction (i.e., the X-axis direction), providing structural support and protection for the cabinet bus 3. Of course, this application is not limited to this. In other embodiments, the cabinet bus 3 is located at the rear edge of the cabinet 91, the main body 31 provides sufficient structural support, and the housing 35 structure is omitted; or, in another embodiment, structural support and protection are provided by the rear cover of the cabinet 91.

[0022] Figure 6 This is a top view of some components of the second embodiment of the power supply rack and cabinet bus. In this embodiment, the power supply rack 2a and the cabinet bus 3a are... Figures 1 to 5The power rack 2 shown is similar to the cabinet bus 3, and the same component labels represent the same components, structures, and functions, which will not be described again here. In this embodiment, the two connection ends of the first connector 23 of the power rack 2a are electrically connected to the first input bus 21 and the second input bus 22, respectively. The two connection ends of each second connector 24, 25 are also electrically connected to the first input bus 21 and the second input bus 22, respectively. Thus, the first connector 23 and the two second connectors 24, 25 form three sets of identical output terminals.

[0023] In this embodiment, the main body 31 of the cabinet bus 3a includes a first output bus 311, an insulating member 313, and a second output bus 312, extending in the vertical direction (i.e., the Z-axis direction). The insulating member 313 is located between the first output bus 311 and the second output bus 312, and together they form a first plug-in interface. The branch member 32 includes a first conductor 321, a spacer 323, and a second conductor 322, wherein the spacer 323 is located between the first conductor 321 and the second conductor 322, and the first conductor 321 and the second conductor 322 are electrically connected to the first output bus 311 and the second output bus 312, respectively. The second plug-in interface formed by the branch member 32 is similar to the first plug-in interface. Similarly, branch member 33 includes a first guide member 331, a spacer 333, and a second guide member 332, wherein the spacer 333 is located between the first guide member 331 and the second guide member 332, and the first guide member 331 and the second guide member 332 are electrically connected to the first output bus 311 and the second output bus 312, respectively. The third plug-in interface formed by branch member 33 is similar to the first plug-in interface. In other words, a pair of branch members 32 and 33 are respectively disposed on both sides of the first connector 23, and the structure forms the same second plug-in interface and third plug-in interface as the main body 31.

[0024] Thus, when the three identical output terminals of the power supply rack 2a, namely the first connector 23 and the second connectors 24 and 25, are simultaneously connected to the branched rack bus 3a, the aforementioned power supply system 1 can increase its current withstand value and achieve higher wattage applications. Of course, this application is not limited thereto.

[0025] Figure 7 This diagram illustrates the correspondence between the power supply rack and the cabinet bus according to a third embodiment of this application. In this embodiment, the power supply rack 2b and the cabinet bus 3b are... Figures 1 to 5The power rack 2 shown is similar to the cabinet bus 3, and the same component labels represent the same components, structures, and functions, which will not be described again here. In this embodiment, the two connection terminals of the first connector 23 on the power rack 2b can be grounded, i.e., configured as a grounding connector. The two connection terminals of the second connector 24 are both connected to the first input bus 21, i.e., configured as a first polarity connector. The two connection terminals of the other second connector 25 are both connected to the second input bus 22, i.e., configured as a second polarity connector. For example, the first connector 23, the second connector 24, and the other second connector 25 provide ground potential, 400V, and -400V voltage outputs, respectively.

[0026] On the other hand, the main body 31a of the cabinet bus 3b can be formed by only copper busbars to form a ground bus GND, while a pair of branch parts 32a and 33a are separated from the main body 31a by insulating parts, and respectively use copper busbar architecture as the first polarity output bus and the second polarity output bus.

[0027] Thus, when the main body 31a and the pair of branch parts 32a and 33a of the cabinet bus 3b are connected to the first connector 23 and the two second connectors 24 and 25 of the power rack 2b, the current withstand value of the aforementioned power supply system 1 can be increased, enabling applications with higher wattage.

[0028] Figure 8 This diagram illustrates the correspondence between the power supply rack and the cabinet bus in the fourth embodiment of this application. In this embodiment, the power supply rack 2c corresponds to the cabinet bus 3c. Figures 1 to 5 The power rack 2 shown is similar to the cabinet bus 3, and the same component labels represent the same components, structures, and functions, which will not be described again here. In this embodiment, the first connector 23 and a pair of second connectors 24 and 25 are also structured as an integrated unit along the direction extending along the cabinet connection side 201 (i.e., the Y-axis direction). This integrated structure ensures that the power rack 2c can be stably and reliably plugged into the cabinet bus 3c, provided that the wiring at the connection ends of the first connector 23 and the second connectors 24 and 25 is not affected. Similarly, the spacing of the branch members 32 and 33 of the corresponding cabinet bus 3c can be further adjusted.

[0029] As can be seen from the above, the power supply system 1 of this application utilizes the wiring variations of multiple connectors 23, 24, and 25 on power racks 2, 2a, 2b, and 2c, and in conjunction with the configuration of multiple plug-in interfaces on cabinet buses 3, 3a, 3b, and 3c, to achieve mutual pairing. This allows the power supply system 1 to overcome the limitations of using a single connector and provide high wattage or more diverse application scenarios. Of course, the number and connection end combination of the first connector 23 and the second connectors 24 and 25, as well as the number and type of branch components 32, 33, 32a, and 33a, can all be adjusted according to actual application requirements, and this application is not limited to these. For example, in the above embodiments, the positive and negative terminals of the first input bus 21 and the second input bus 22 are only for illustrative purposes. The first input bus 21 in each figure can also be configured to connect to a negative voltage and the second input bus 22 to connect to a positive voltage, or the first input bus 21 can be configured to connect to a positive voltage and the second input bus 22 to connect to ground potential, and other suitable power supply connection methods.

[0030] In the above embodiments, the terms "input" and "output" in the power rack input bus and the rack bus output bus are for simplification only and do not imply that power can only be transmitted from the power rack to the rack bus. In other implementations, depending on the characteristics of the power supply units and / or load units installed in the power rack, the power rack input bus and the rack bus output bus can respectively play the roles of power input and / or power output. For example, when the power rack is equipped with a BBU unit, the power rack may, at time point A, transfer power from the battery to the output bus from the input bus, and at time point B, receive power from the output bus and charge the battery from the input bus.

[0031] In summary, this application provides a power supply system, a related power supply rack, and a related cabinet. By designing multiple sets of output terminals between the power supply rack and the cabinet, the power supply system can exceed the maximum current withstand capability. Multiple connectors are arranged in the power supply rack to form, for example, at least three sets of output terminals, and two branch members are correspondingly added to opposite sides of the main body of the cabinet bus, enabling the power supply system to exceed the maximum current withstand capability. When the main body consists of a first output bus and a second output bus forming a first plug-in interface, the branch members on both sides are respectively fixed to the first and second output buses by fasteners, forming a pair of plug-in interfaces with opposite polarities. When the three sets of output terminals of the power supply rack are simultaneously connected to the branched cabinet bus, the current withstand value can be tripled, enabling higher wattage applications. Of course, the branch members can also be composed, for example, of a spacer, a first conductor, and a second conductor. The first and second conductors are insulated by the spacer and electrically connected to the first and second output buses respectively, forming a pair of plug-in interfaces identical to the main body. Thus, when the three sets of output terminals of the power supply rack are simultaneously connected to the three sets of plug-in interfaces, the power supply system's current withstand value can be increased, enabling applications with higher wattage. Furthermore, the main body of the cabinet bus and the branch components on both sides can also be directly configured as a ground bus, a first output bus, and a second output bus, interfacing with the three connectors of the power supply rack to achieve diverse applications of the power supply system. On the other hand, the cabinet bus is easily reconfigured with a shell to provide structural support and protection. Moreover, the multiple connectors of the power supply rack can be configured into a single integrated structure to facilitate miniaturization and increase the power density of the power supply system.
