Abstract
The invention provides a power supply system of a server and a server cabinet. The power supply system of the server comprises a power factor corrector (PFC) and a bus conversion module (BCM), wherein the power factor corrector receives 220V power voltage, increases power factors and outputs 380V power voltage; and the bus conversion module receives the 380V power voltage outputted by the PFC and converts the 380V power voltage into power voltage higher than 48V. By the power supply system of the server, high power voltage can be provided for the server.
Description
Technical field
The present invention relates to field of computer technology, particularly a kind of electric power system of server and server cabinet.
Background technology
At present, generally adopt power module (PSU) supply voltage of 220V to be converted to the supply voltage of 12V, be supplied to server, to complete power supply.
But, in a lot of server system, often need higher supply voltage, to provide big current powerful support.
Summary of the invention
The invention provides a kind of electric power system and server cabinet of server, so that provide higher supply voltage.
An electric power system for server, comprising:
Power factor corrector PFC, receives 220V supply voltage, carries out the process of raising power factor, exports 380V supply voltage;
Bus conversion module BCM, receives the 380V supply voltage that described PFC exports, is converted to the supply voltage of more than 48V.
Comprise further: voltage conversion circuit and voltage selection module;
Described voltage conversion circuit, connects described BCM, and the 48V supply voltage that BCM exports is converted to 12V supply voltage;
Described voltage selection module, connects described BCM and described voltage conversion circuit, exports for selecting a road voltage in the 12V supply voltage that the 48V supply voltage that exports from described BCM and described voltage conversion circuit export.
Comprise further: reserce cell, connect described BCM and server, for providing backup power supply to server.
Described reserce cell is lithium battery.
A kind of server cabinet, comprising:
More than one reserce cell, corresponding to one group of blade of each reserce cell, and the electric power system of above arbitrary described server.
Embodiments provide a kind of electric power system and server cabinet of server, utilize PFC and BCM to form electric power system, and by the mode of multistage conversion, first 220V supply voltage is promoted to 360V supply voltage, and then is converted to 48V supply voltage.The way of 12V supply voltage can only be provided relative to prior art, then can provide higher supply voltage, thus provide the powerful support of big current.
In addition, in the embodiment of the present invention, reserce cell can be installed additional at power end and BCM end, instead of install the reserce cell carrying out backing up power supply for this chip in certain die terminals concrete of server end additional, thus power supply backup can be carried out for all chip modules in whole server.
Accompanying drawing explanation

Fig. 2 is the schematic diagram of the electric power system of server in another embodiment of the present invention.
Fig. 3 installs at power supply side the schematic diagram that reserce cell powers to server additional in one embodiment of the invention.
Fig. 4 is the structural representation of server cabinet in one embodiment of the invention.
Embodiment
One embodiment of the invention proposes a kind of electric power system of server, see Fig. 1, comprising:
Power factor corrector (Power Factor Correction, PFC), receives 220V supply voltage, carries out the process of raising power factor, exports 380V supply voltage;
Bus conversion module BCM (Bus converter module), receives the 380V supply voltage that described PFC exports, is converted to the supply voltage of more than 48V.
Visible, the electric power system of the server of the above embodiment of the present invention, utilizes PFC and BCM to form electric power system, and by the mode of multistage conversion, first 220V supply voltage is promoted to 360V supply voltage, and then is converted to 48V supply voltage.The way of 12V supply voltage can only be provided relative to prior art, then can provide higher supply voltage, thus provide the powerful support of big current.
See Fig. 2, in order to make electric power system more flexible in use further, meeting multiple demand, in another embodiment, the architecture basics of electric power system shown in Fig. 1 may further include: voltage conversion circuit and voltage selection module,
Described voltage conversion circuit, connects described BCM, and the 48V supply voltage that BCM exports is converted to 12V supply voltage;
Described voltage selection module, connects described BCM and described voltage conversion circuit, exports for selecting a road voltage in the 12V supply voltage that the 48V supply voltage that exports from described BCM and described voltage conversion circuit export.
See Fig. 2, the electric power system due to this embodiment of the invention can provide 48V and 12V two kinds of supply voltages, therefore, can, according to the actual use needs of server, select a kind of supply voltage to export flexibly.
In one embodiment of the invention, the architecture basics of the electric power system shown in Fig. 1 or Fig. 2 may further include reserce cell, to carry out backup power supply to power supply.To comprise reserce cell on architecture basics shown in Fig. 1, see Fig. 3, reserce cell connects the server of BCM and outside, for providing backup power supply to server.Like this, if provide the system of 48V to break down, reserce cell continues power supply, and server system can not be closed immediately, data cached if having time, then the power-supply system more renewed.
In some embodiments of the invention, reserce cell can be lithium battery, thus charges when power supply normally works, and when power fail, discharges to provide backup battery.
It should be noted that, in embodiments of the present invention, as BCM place installs reserce cell additional at power end, therefore be the backup for whole power supply, instead of install additional only for the reserce cell of this chip in certain die terminals concrete of server end, thus power supply backup can be carried out for all chip modules in whole server.
See Fig. 4, propose a kind of server cabinet in one embodiment of the invention, comprising:
More than one reserce cell, corresponding to one group of blade of each reserce cell, and the electric power system of the server of any one embodiment of the present invention above-mentioned proposition.
It should be noted that, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element " being comprised " limited by statement, and be not precluded within process, method, article or the equipment comprising described key element and also there is other same factor.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
