Abstract
The invention provides an AC and DC hybrid redundant power supply method. A power supply module is provided with two paths of AC input, wherein one path of AC input is connected with a mains supply, and the other path of AC input is connected with a 48V rechargeable battery; the AC input is connected in series with an AC/DC conversion module and a power output interface ATX; and the 48V rechargeable battery is connected with a DC/DC conversion module and the power output interface ATX. The AC and DC hybrid redundant power supply method comprises the following steps that: under the condition of normal running of the mains supply, the AC/DC conversion module provides power output for the power output interface ATX, and also charges the 48V rechargeable battery by the DC/DC conversion module; and under the condition of abnormal running of the mains supply, the 48V rechargeable battery supplies power to the power output interface ATX.
Description
Technical field
The present invention relates to server power supply system power supply field, specifically a kind of AC and DC hybrid redundancy method of supplying power to.
Background technology
The fast development of the Internet makes information resources present explosive growth, and people are medium with the network, and the demand of information is also constantly being increased.Various large-scale data machine rooms also arise at the historic moment.The quantity of the individuality-server of composition data machine room, storage rack is also in continuous increase.Along with the continuous development of the Internet, information security technology constantly perfect, traditional government administration work, commercial operation business etc. have all realized networking, informationization.These business are high especially to the security requirement of data.Reliable operation performance height to the hardware carrier of data has proposed very high requirement.Power supply form to the hardware at data center also presents diversified development trend.Thus, this paper has proposed the method for designing of a kind of input tape AC and the power supply of DC hybrid redundancy.
Summary of the invention
The purpose of this invention is to provide a kind of AC and DC hybrid redundancy method of supplying power to.
The objective of the invention is to realize in the following manner, the input of No. one alternating current is set respectively in power module to be electrically connected with the city, another road is connected with the 48V storage battery, wherein alternating current input serial connection AC-DC conversion modules A C/DC is connected with power output interface ATX, the 48V storage battery connects the DC/DC modular converter and is connected with power output interface ATX, the power supply step is as follows: DC conversion modules AC/DC is the 48V charge in batteries by the DC/DC modular converter also for power output interface ATX provides power supply output under the civil power normal condition, under the civil power abnormal conditions, be power output interface ATX power supply by the 48V storage battery.
AC and DC hybrid redundancy method of supplying power to of the present invention is compared with prior art, beneficial effect is: have reasonable in design, simple in structure,, easy to use, the reliability that strengthened whole power supply (if: under the condition of AC civil power massive blackout, DC still can provide power supply, the applicability that has strengthened power supply simultaneously not only is confined to adopt AC to come to characteristics such as redundant power power supplies, thereby, have good value for applications.
Description of drawings
Accompanying drawing 1 is the electric power-feeding structure schematic diagram of traditional redundant power
Accompanying drawing 2 is power supply architecture schematic diagrames of AC and the power supply of DC hybrid redundancy.
Embodiment
Explain below with reference to Figure of description method of the present invention being done.
Shown in the electric power-feeding structure of traditional redundant power of accompanying drawing 1, this power supply architecture is to give the power supply of the power module in the power supply respectively with two groups of AC, and after the civil power outage that connects two groups of AC ends, power supply quits work, thereby causes the server system machine of delaying.
Fig. 2 is the power supply architecture of a kind of AC of employing and DC hybrid power supply.Wherein, DC is one of them power module power supply, and the energy conversion form of this power module is the conversion regime of DC/DC, so, has improved power source integral efficient to a certain extent; AC is another power module power supply, and two power modules are combined and realized the 1+1 redundancy.This structure has constantly strengthened the reliability (if: under the condition of AC civil power massive blackout, DC still can provide power supply) of whole power supply, has strengthened the applicability (not only being confined to adopt AC to come to the redundant power power supply) of power supply simultaneously.
In traditional server redundancy power supply, each power module all adopts the AC supply power mode, and difference of the present invention is the supply power mode of one of them power module is become direct current supply, and the mapping mode of this power module is simultaneously: the conversion regime of DC/DC.For power source integral, feeder ear adopts AC and two kinds of supply power modes of DC, and the AC electricity is given one of them power module power supply, and the DC electricity is given another power module power supply.The AC electricity is generally electric main, and DC generally is to adopt battery pack to provide or by circuit conversion is-48VDC.In case opening circuit appears in electric main, battery pack can guarantee that still wherein a power module works on, thereby guarantees the power supply of whole system.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (1)
1. AC and DC hybrid redundancy method of supplying power to, it is characterized in that being provided with respectively in power module the input of No. one alternating current is electrically connected with the city, another road is connected with the 48V storage battery, wherein alternating current input serial connection AC-DC conversion modules A C/DC is connected with power output interface ATX, the 48V storage battery connects the DC/DC modular converter and is connected with power output interface ATX, the power supply step is as follows: DC conversion modules AC/DC is the 48V charge in batteries by the DC/DC modular converter also for power output interface ATX provides power supply output under the civil power normal condition, under the civil power abnormal conditions, be power output interface ATX power supply by the 48V storage battery.
