Detailed description of the invention
Below with reference to the drawings, the present invention is described in further detail.
As it is shown in figure 1, a kind of power supplying system of server 100 provided for first embodiment of the invention, it is for providing electric energy at least one load 200; In present embodiment, described load 200 is blade server. Described power supplying system of server 100 includes a supply socket 10, multiple power supply module 20, bus 30 and controls module 40. Described power supply module 20 is connected between supply socket 10 and described bus 30 in order to the electric energy obtained from described supply socket 10 is delivered to described bus 30, described control module 40 is connected the break-make controlling described power supply module 20 with described power supply module 20, and described load 200 is all connected with described bus 30.
Described supply socket 10 includes an input and multiple outfan, and described input is connected with civil power; The civil power inputted from input is divided into plurality of voltages and all equal electric energy of electric current by this supply socket 10, and exports from outfan respectively. In present embodiment, described supply socket 10 includes six outfans.
Described each power supply module 20 includes an AC-DC module 21, and described AC-DC module 21 includes an input, an outfan and the switch module 22 being connected between input and outfan. The input of described AC-DC module 21 is connected with the outfan of described supply socket 10. The AC conversion that described AC-DC module 21 receives for being inputted end is unidirectional current, and the output of the input power of the input of AC-DC module 21 and outfan differs.
