Description
Technical field
The present invention relates to field of power supplies, particularly, relate to a kind of alternating current-direct current mixed type server power supply.
Background technology
Usually, server power supply is exactly to instigate the power supply (POWER) that is used on the server, and it is the same with PC (PC) power supply, all is a kind of Switching Power Supply.Server power supply can be divided into two kinds of ATX power supply and SSI power supplys according to standard.The ATX standard is used comparatively general, is mainly used in desktop computer, work station and low-end server; And the SSI standard produces along with the development of server technology, is applicable to the server of various class.
The ATX standard is the standard that Intel released in 1997, and power output is generally between 125 watts～350 watts.The ATX power supply adopts the double rectangle socket of 20 pins (20Pin) to give main board power supply usually.Along with Intel releases the Pentium4 processor; Power specifications also is revised as ATX12V by ATX; Compare with the ATX power supply, the ATX12V power supply has mainly increased the 12V power output end of a 4Pin, so that satisfy the power reguirements (the P4 power consumption of 2GHz dominant frequency reaches 52.4 watts) of Pentium4 better.
The SSI standard is the new services device power specifications that some main Intel Architecture server manufacturers of Intel associating release; The release of SSI standard is for standard server power supply technology; Reduce development cost; Formulate the useful life that prolongs server, mainly comprises server power supply specification, back board system specification, the machine box for server system specification and cooling system specification.
Along with popularizing of networking and datumization, server is more and more higher to power source voltage retention time, redundancy, the requirement of aspects such as support property, stability and fail safe to mainboard.But above-mentioned server power supply is generally single AC power or DC power supply, during actual the use, AC power need be converted into DC power supply usually or convert DC power supply into AC power.

In sum, in realizing process of the present invention, the inventor finds to exist at least in the prior art following defective:
⑴ a little less than the power supply compatibility: can only merely AC power or DC power supply be provided for server;
⑵ reliability is low: when single AC power or DC power supply are supplied power to server, if this AC power or DC power supply fault, then server power failure; When AC power being converted into DC power supply or converting DC power supply into ac power supply, if run into fault or other reason when causing power failure, the server power supply also possibly interrupted at any time, makes that the server power supply is unreliable;
⑶ poor stability: when the server power supply was interrupted suddenly, the data on the server had little time to preserve, and cause mass data to be lost, and fail safe is not high;
⑷ it is inconvenient that use: when AC power being converted into DC power supply or converting DC power supply into AC power, all change-over circuit need be set separately.
