[0002] With the strong development of the world's demand for AI computing power, the performance of CPU and GPU intelligent computing chips has developed rapidly, and the power consumption has increased rapidly accordingly. The power consumption of a single server cabinet has also increased rapidly, from the traditional 5kW / cabinet to 10kW / cabinet, reaching 30kW / cabinet, and even 100kW / cabinet - 300kW / cabinet. Therefore, high-power 48V DC server power supplies must be placed inside the server cabinet to supply power to the servers with a 48V input voltage nearby. According to the high reliability requirements of the power supply in the data center, each power rectification module needs to be configured with a dual-channel ATS automatic power input. The dual-channel power supply should support two-way AC input, or one-way AC input and one-way DC input, or two-way DC input. Among them, the AC power supply is divided into single-phase, two-phase, 3P+N+PE, and 3P+N. With these input power supply systems and dual-channel input, there are more than a dozen input power supply systems after combination.

This solution solidifies power supply products of different systems, lacks flexibility, has a large number of non-universal power supply product categories, and causes difficulties in customer selection and resource waste.

[0033] The server power supply provided by the present utility model includes an input terminal and a shorting piece accessory, and the input terminal is flexibly adjusted according to the actual input power supply system on site to adapt to various input power supply systems, thus solving the problems of needing to produce corresponding power supply products according to different systems and needing to select corresponding power supply products according to the on-site input power supply system, and significantly improving the flexibility and availability of the power supply products.

[0034] The embodiment of the present utility model provides a server power supply, which is arranged in a server cabinet and supplies power to the servers in the cabinet. The server power supply includes at least one power plug frame;

A first power input end and a second power input end are arranged outside each layer of the power supply insertion frame; each rectification module is provided with two-way power ATS (Automatic Transfer Switch Power) circuits. The first power input end and the second power input end respectively supply main power and standby power to the rectification modules in the same layer; the rectification module includes a DC output port.

[0036] In the embodiment of the present utility model, the server rack can install devices such as 21-inch or 19-inch servers or power supplies. In the height direction of the cabinet, 1U (about 44.45 mm) is used as the basic unit. The height of the server power supply in the embodiment of the present utility model is 2U, and each 1U height is one layer. As Figure 1 shown, 6 rectification modules are arranged in each layer of the power supply insertion frame, and one first power input end and one second power input end are provided by every 6 rectification modules. In practical applications, the number of power supply insertion frames is determined according to the total load of the server cabinet and the capacity of each power supply insertion frame.

[0037] As Figures 2-3 shown, both the first power input end and the second power input end include an input terminal socket and an input terminal plug. The input terminal socket is arranged in the visible area outside the power supply insertion frame; an external power supply is connected to the input terminal plug through an external cable. The input terminal plug is connected to the input terminal socket, the input terminal socket is connected to the power supply circuit board, the power supply circuit board conducts current into the rectification module, the rectification module processes the input power supply and outputs DC power through the DC output port, and the server is connected to the DC output port; the external power supply is an AC power supply or a DC power supply. If the external power supply is an AC power supply, the rectification module converts the alternating current into direct current. If the external power supply is a DC power supply, the rectification module converts the input high-voltage direct current into low-voltage direct current. In the embodiment of the present utility model, the DC output voltage is 48V.

[0038] The pin definitions of the input terminal socket and the input terminal plug are the same.

In some embodiments of the present utility model, the conductor is a wire core, and the insulating layer is a plastic insulating hollow column wrapped around the wire core. The shorting piece is a metal piece, and the part of the shorting piece connected to the conductor can also be wrapped with a plastic insulating hollow column, leaving only enough length for electrical connection. In the embodiment of the present utility model, when using the first shorting member, the external cable is connected through the middle shorting piece of the first shorting member. The advantage of connecting the external cable from the middle shorting piece rather than from any one of the other two shorting pieces is that the current flowing through the conductor connecting the respective shorting pieces is smaller, and the cross-sectional area of the conductor can be smaller, saving the size of the conductor.

As Figure 8 As shown, when the external power supply is single-phase three-phase 3P+PE AC input, after using the second shorting piece to short-circuit the pins of the input terminal plug, connect the three-phase live wires in the manner shown in Figure 8 shown.

As Figure 9 As shown, when the external power supply is single-phase L / N AC input, after using the first shorting piece to short-circuit the pins of the input terminal plug, connect one single-phase live wire and the neutral wire in the manner shown in Figure 9 shown. As Figure 10As shown, when the external power supply is a 1-way dual-phase AC input of L1 / L2, after short-circuiting the pins of the input terminal plug using the first shorting piece, connect it to a 1-way dual-phase AC according to the method shown in Figure 10 . As shown in Figure 11 , when the external power supply is a 1-way DC input, after short-circuiting the pins of the input terminal plug using the first shorting piece, connect it to a 1-way DC power supply according to the method shown in Figure 11 .

[0045] Figure 12 FIG. is a schematic diagram of the connection between the power plug frame and the rectification module provided by the embodiment of the present invention. Among them, the power plug frame has two layers, and the structure in each layer corresponds to that in Figure 1 . Each layer includes two power input terminals and 6 rectification modules. The external power supply is introduced into the power plug frame through a power plug (i.e., the input terminal plug mentioned above) and a power socket (i.e., the input terminal socket mentioned above).

The rectification module processes the input power supply and outputs direct current through the DC output port. The DC output port includes a positive output port and a negative output port.
