For convenience of description, the working principle of the power supply system is described below by taking the multi-phase ac power grid as the three-phase ac power grid and the load as the server device as an example.
Exemplarily, referring to fig. 4, fig. 4 is another schematic architecture diagram of the power supply system provided in the present application. As shown in fig. 4, the power supply system 1 includes a rectification conversion module 10, dc conversion modules 111 and … …, and a dc conversion module 11 n. The rectification conversion module 10 includes an pluggable rectification input terminal 101, pluggable DC bus output terminals 1021, … …, a pluggable DC bus output terminal 102n, an AC/DC circuit 103, and a first controller 104, wherein an input terminal of the AC/DC circuit 103 is connected to the pluggable rectification input terminal 101, and an output terminal of the AC/DC circuit 103 is connected to the pluggable DC input terminals 1111, … …, and the pluggable DC input terminal 11n 1. When the DC conversion module 111 needs to be connected to the rectifying conversion module 10, the DC conversion module 111 may be connected to the pluggable DC bus output terminal 1021 by plugging the pluggable DC input terminal 1111 into the pluggable DC bus output terminal 1021; … …, respectively; the DC conversion module 11n includes a pluggable DC input terminal 11n1, a DC/DC circuit 11n2, and a second controller 11n3, and when the DC conversion module 11n needs to be connected to the rectification conversion module 10, the pluggable DC input terminal 11n1 may be plugged to the pluggable DC bus output terminal 102n, so as to implement connection between the DC conversion module 11n and the rectification conversion module 10. The input end of the AC/DC circuit 103 is connected with a three-phase alternating current power grid through the pluggable rectification input terminal 101, the output end of the AC/DC circuit 103 is connected with the input end of the DC/DC circuit 1112 through the pluggable direct current bus output terminal 1021 and the pluggable direct current input terminal 1111, and the output end of the DC/DC circuit 1112 is connected with the server device 1; … …; the output terminal of the AC/DC circuit 103 is connected to the input terminal of the DC/DC circuit 11n2 via the pluggable DC bus output terminal 102n and the pluggable DC input terminal 11n1, and the output terminal of the DC/DC circuit 11n2 is connected to the server device n.
In an optional embodiment, when it is detected that the pluggable rectification input terminal 101 is connected to the three-phase AC power grid and one or more DC conversion modules of the n DC conversion modules are connected to the rectification conversion module 10, the first controller 104 outputs a first driving signal (i.e., a square wave) to the AC/DC circuit 103, where the first driving signal is used to control the on-time of a switch in the AC/DC circuit 103, so that the AC/DC circuit 103 converts the AC power input by the three-phase AC power grid into a first DC power with an output voltage of the first DC voltage. The AC/DC circuit 103 is a high-power AC/DC circuit, and it is not necessary to use a plurality of low-power AC/DC circuits to achieve high-power output, so that the conversion efficiency of the power supply system 1 can be effectively improved, and the cost and volume of the power supply system 1 can be reduced.
Then, the AC/DC circuit 103 outputs the first direct current to one or more direct current conversion modules connected to the rectification conversion module 10. Assuming that one or more dc conversion modules connected to the rectifying and converting module 10 include the dc conversion module 111, since the operating principles of the dc conversion modules connected to the rectifying and converting module 10 are the same, the following description will take the dc conversion module 111 as an example.
AC/DC circuit 103 outputs a first direct current to an input terminal of DC/DC circuit 1112 through pluggable direct current bus output terminal 1021 and pluggable direct current input terminal 1111. The second controller 1113 obtains a target operating voltage (i.e., an optimal operating voltage) required by the server apparatus 1 by communicating with the server apparatus 1, generates a second driving signal (i.e., a square wave) according to the target operating voltage required by the server apparatus 1 and the first direct-current voltage, and outputs the second driving signal to the DC/DC circuit 1112. The second driving signal is used to control the on-time of a switching tube in the DC/DC circuit 1112, so that the DC/DC circuit 1112 converts a first direct current with an output voltage of a first direct current voltage into a second direct current with an output voltage of a second direct current voltage, where the first direct current voltage is greater than or equal to the second direct current voltage, and a voltage deviation between the second direct current voltage and a target operating voltage is less than a voltage deviation threshold. Then, the DC/DC circuit 1112 outputs the converted second direct current to the server apparatus 1 to supply power to the server apparatus 1. It can be understood that the dc conversion module can obtain the target working voltage required by the server device through real-time communication with the server device connected to the dc conversion module, and adjust the output voltage of the dc conversion module in real time according to the target working voltage required by the server device, so as to ensure that the dc conversion module can output the target working voltage as required, thereby effectively reducing the power consumption of the power supply system 1.
It should be noted that, in order to avoid the situation that the number of the server devices is too large, which causes the wires between the server devices and the dc conversion modules to be too disordered, the power supply system 1 may further include at least one tray, where each tray is used to place at least one dc conversion module and the server device connected to each of the at least one dc conversion module. It can be understood that the tray can enable the connection between the server equipment and the direct current conversion module to be more tidy under the condition that the server equipment is too much, so that the power supply system 1 is more convenient to install in the early stage and maintain in the later stage, and the working efficiency of workers is improved. Here, the present application does not limit the specific placement manner of the dc conversion module located on the tray and the server device connected to the dc conversion module.
Exemplarily, assuming that n =3, the power supply system 1 includes a dc conversion module 111 to a dc conversion module 113, the dc conversion module 111 is connected to the server apparatus 1, the dc conversion module 112 is connected to the server apparatus 2, the dc conversion module 113 is connected to the server apparatus 3, and the tray 1 is used for placing the dc conversion module 111 to the dc conversion module 113, and the server apparatus 1 to the server apparatus 3. Then, the 3 dc conversion modules and the 3 servers on the tray 1 may be sequentially placed according to the order of the dc conversion module 1, the server apparatus 1, the dc conversion module 2, the server apparatus 2, the dc conversion module 3, and the server apparatus 3, or sequentially placed according to the order of the dc conversion module 1, the dc conversion module 2, the dc conversion module 3, the server apparatus 1, the server apparatus 2, and the server apparatus 3. Wherein, place direct current conversion module and the server equipment who links to each other rather than according to adjacent mode, can make and be more convenient when carrying out installation in earlier stage and later maintenance to power supply system 1 to improve staff's work efficiency.
In this embodiment, power supply system 1 can realize the power supply to one or more server equipment according to above-mentioned mode, because the connection of rectification conversion module 10 and three-phase alternating current electric wire netting, direct current conversion module all adopts the form that can electrified plug terminal to connect, easy operation, consequently no matter be in early system installation or when later stage system maintenance, all can reduce the work degree of difficulty, reduce work load in a large number to reduce installation and maintenance error rate, improve work efficiency, the suitability is strong.
