Abstract
The invention provides a method for implementing alternating-current power supply redundancy, which comprises the following steps of: converting different alternating current of each path in a server system into direct current through respective rectification module for isolation, and then connecting the direct current in parallel to supply power to the connected equipment or system. The method has the advantages that: the circuit design is simple; and the method is convenient to implement operation, can be applied to a single server or a single storage device and also can be applied to a complete cabinet product consisting of multiple servers or storage devices, so the method has very broad development prospect.
Description
Technical field
The present invention relates to server and storage power supply field, specifically a kind of method that realizes redundancy of alternating current power supply.
Background technology
Based on the consideration to Supply Security, aspect equipment, i.e. redundant power has all been adopted in server or storage etc. at present, can not cause system-down when avoiding certain supply module to lose efficacy.Aspect machine room, adopted UPS (uninterruptible power system) on the one hand, also realized the automatic switchover of at least 2 tunnel different input AC electricity on the other hand, to guarantee that certain road input AC electricity can switch to another road alternating current rapidly to restore electricity when breaking down, then born the power supply of whole equipment room by UPS between transfer period.Can infer, this way is not only complicated, and adding needs UPS, and efficient is not high, and machine room be if dilatation then might need modernization overlay, exchange device more, and cost can be very high.
Some new data center machine room is also in the middle of building now, some clients consider from energy-conservation angle, wish to take away UPS, but save the interchange redundant power supply again from damage, for this reason, traditional implementation method is exactly that the alternating current that each road is different passes through circuit design, export No. one alternating current at last and give power devices, the shortcoming of doing like this is, because each group alternating current is homophase not, directly short circuit is obviously unworkable together, must pass through complex circuit design, allow each road alternating current realize Phase synchronization accurately, and reach load balancing.Though this technology can realize that this method realizes that by rectification module separately redundancy of alternating current power supply is better simple and convenient respectively with each road alternating current.
Summary of the invention
The purpose of this invention is to provide a kind of method that realizes redundancy of alternating current power supply.
The objective of the invention is to realize in the following manner, is alternating current that each road in the server system is the different rectification module by separately respectively, and after alternating current was converted to direct current and isolates, being connected in parallel was connected equipment or system's power supply again.
Method beneficial effect of the present invention is: circuit design is simple, realizes easy to operately, both can be applicable to separate unit server or memory device, also can be applicable to the complete machine cabinet product that is made of multiple servers or memory device, thereby has boundless development prospect.
Description of drawings
Fig. 1 is traditional interchange redundant power supply schematic diagram;
Fig. 2 is the power supply redundancy approach schematic diagram of this method.
Embodiment
With reference to Figure of description to explaining below the work of the present invention.
As shown in drawings, a kind of method that realizes redundancy of alternating current power supply of the present invention, be that the alternating current that each road in the server system is different passes through rectification module separately respectively, after will exchanging (AC) and converting direct current (DC) to and isolate, being connected in parallel is connected equipment or system's power supply again, thereby has avoided directly each road alternating current being carried out the complex operations and the design of load balancing and phase control.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (1)
1. method that realizes redundancy of alternating current power supply is characterized in that the alternating current that each road in the server system is different rectification module by separately respectively, and after alternating current was converted to direct current and isolates, being connected in parallel was connected equipment or system's power supply again.
