Technical field

The present invention relates to the energy-conservation power supply method for designing of a kind of novel server power supply, compatible two-way input voltage simultaneously, is respectively the energy-conservation power supply method for designing of server that tri-kinds of situations of AC 1 and AC 2 or AC 1 and DC 1 or DC 1 and DC2 are inputted.AC voltage refers to that input electrical network scope is that alternating voltage is 200 ~ 240V, and Dc voltage refers to that input electrical network scope is that DC voltage is 200 ~ 280V.

Technical background

Along with the development of infotech, Internet technology is advanced by leaps and bounds, and the Constructing data center of enterprise of China and mechanism has entered the fast-developing new stage, has formed the new upsurge of building.Concentrating of data and concentrating on when bringing huge interests of computing power, also propose new requirement to the construction of data center.

In the essential characteristic of New Generation of IDC, there is following principal character: modularization, extendible ability, energy-conservation and save space, high IT resource utilization, high reliability Redundancy Design etc. fast.

For traditional data center, generally adopt two-way or multichannel UPS power supply, because supply line is without available backup, when after civil power power-off, easily there is situation; And in UPS, needing voltage inversion, energy utilization rate is low.Under traditional mode, power supply is operated under low load mode more, and efficiency is low.

Summary of the invention

The technical problem to be solved in the present invention is: change the present situation that uses traditional powering mode inefficiency, energy dissipation.

For this reason, on the basis of traditional UPS power supply, increase by a road high-voltage DC power supply power supply, or use two-way civil power, backup each other with traditional UPS power supply, when after UPS power-off, high-voltage DC power supply can continue power supply, guarantees that server cabinet normally moves, and has improved server reliability of operation; High voltage direct current power supply simultaneously, due to no-voltage inversion process, so the conversion efficiency of electric energy is high more a lot of than traditional UPS, reaches energy-saving effect.

In the situation that there is no high voltage direct current, also can use two-way mains-supplied, but employs power active+standby function allows power work at efficient state, green energy conservation.

The technical solution adopted in the present invention is:

The energy-conservation power supply method for designing of a kind of novel server power supply, server power supply input pattern is for being respectively tri-kinds of situations of AC and AC or AC and DC or DC and DC, wherein, AC voltage refers to that input electrical network scope is that alternating voltage is 200 ~ 240V, Dc voltage refers to that input electrical network scope is that DC voltage is 200 ~ 280V, use customization general-purpose version power supply firmware function program (simultaneously compatible AC-3 AC, AC DC, DC DC many services device power supply input pattern), the Firmware PMBUS function program of power-on, under the operating systems such as server Linux, input PMbus input instruction, after three kinds of voltage modes of input of self-opening power supply, use the general-purpose version power supply firmware function program of customization by server B MC instruction, make power module enter as required the idle function of a module of active+standby, a module enters sleep mode automatically, once a road power supply occurs abnormal, another module can be waken up from sleep mode automatically, enter the work of primary module.Improve energy utilization rate, reach green energy conservation requirement; Another road power supply can meet backup, has significantly improved the reliability of power supply.

Described method specific operation process is as follows:

1) at the inner single-chip microcomputer with input measuring ability that increases of power supply, single-chip microcomputer judges input according to the input signal collecting:

If detect for sinusoidal wave data, input be AC;

If single linear pattern signal detected, represent to be input as DC;

If the data of can't detect, indicate without power supply input;

2) single-chip completes after the detection of input, and detection line stores testing result on the special address bit of PMbus (as: 0x80h) into, if AC power supply, storage data 0x01, if DC power supply, storage data 0x02, during without power supply input, storage 0x00;

3) after power supply connects, power supply, according to the return message of 0x80, judges the functional mode of active+standby:

In the time 0x01 and 0x01 or 0x02 and 0x02 being detected, electric power starting active+standby function, and enter standby pattern by instruction designated module as required;

In the time 0x01 and 0x02 being detected, electric power starting active+standby function, and the module of DC input (rreturn value is 0x02) is entered standby state by acquiescence;

In the time that rreturn value is 0x01 and 0x00 or 0x02 and 0x00, Power supply is abnormal, and need to detect rreturn value is the power supply state of 0x00 module, determines whether this module is damaged.

According to the powering mode of different situations and energy-conservation demand, utilize general-purpose version power supply firmware function program (compatible AC-3 AC, AC DC, DC DC pattern), power-on active+standby function, convert the underrun simultaneously of two power supplys to power supply medium or higher load operation, improve power work efficiency.

Input instruction by PMbus, reduce cpu frequency (can be selected according to actual requirement), thereby reduce server input power consumption, make power work under high efficiency mode.

A power module can be switched to another module work after operation a period of time, and such two module alternate runs can reduce the probability that power supply damages greatly, improve the reliability of power supply.

Beneficial effect of the present invention is:

Adopt the inventive method, can improve data center's power supply reliability, also improved energy utilization rate and power work efficiency, green energy conservation, has changed the present situation that uses traditional powering mode inefficiency, energy dissipation simultaneously.
