Embodiment Construction

[0012] see figure 1 , a preferred embodiment of the present invention provides a power supply device 100, which is suitable for a computer system using multiple servers to supply power to the multiple servers. In this embodiment, the power supply device 100 is used as an example in a 4in1 (four-in-one) product of a commonly used 2U (Unit, is a unit representing the external size of the server, 1U=4.445cm) server system illustrate. The 4in1 product of this 2U server system includes four servers A1-A4. The power supply device 100 can selectively supply power to one or more of the four servers A1-A4.

[0013] Please also refer to figure 2 , the power supply device 100 includes a first power supply 10 , a control circuit 20 and a gate circuit 30 . The first power source 10 may be an existing power source device such as a battery or a commercial power access device. The control circuit 20 includes four first buffers Buffer1-Buffer4 respectively corresponding to the above-ment...

Abstract

The invention provides a power supply device which comprises a first power supply and a gating circuit, wherein the gating circuit comprises a plurality of NOT gates, a plurality of controllers and a plurality of transistors; input ends of the plurality of the NOT gates are connected to corresponding servers respectively; output ends of the NOT gates are connected to corresponding controllers respectively; a grid electrode of each transistor is connected to a corresponding controller; all drain electrodes are connected to the first power supply; source electrodes of the plurality of the transistors are connected to the corresponding servers; when any one or more servers is / are required to be started, the server required to be started produces a starting signal; the starting signal passes through corresponding NOT gates respectively and then is transmitted to a controller corresponding to the server required to be started, so that the controller outputs a corresponding conduction signal and further controls a transistor corresponding to the server required to be started to be conducted, the server required to be started is connected to the first power supply through the conducted transistor, and electric energy is obtained from the first power supply.

Description

technical field [0001] The invention relates to a power supply device, in particular to a power supply device applied to a server system. Background technique [0002] Many computer systems today can use multiple servers at the same time. For example, the 4in1 (four-in-one) product of the commonly used 2U (Unit, is a unit representing the external size of the server, 1U=4.445cm) server system can put four servers in a 2U server system and share a hard disk back. board, and each server can control multiple hard disks through the hard disk backplane, which significantly improves the data processing capability of the system. Because these servers typically work independently, each server must have a power supply that is not affected by the other servers. However, if a dedicated power supply is configured corresponding to each server, it will obviously lead to a complicated structure of the server system and an increase in cost. Contents of the invention [0003] In view of...
