Fig. 1 is the block diagram for the overall arrangement for schematically showing the electronic equipment 10 according to the present invention.According to the electricity of the present invention Sub- equipment 10 can be various types of servers such as Workgroup Servers, enterprise-level server, can also be large scale computer, Giant computer, supercomputer etc..But the present invention is not limited thereto, those skilled in the art can also be by sheet described below The principle of invention is applied in other suitable multi power supply devices, to improve the power-efficient of the electronic equipment.Below In, for the ease of description, electronic equipment 10 will be illustrated by taking server as an example.

As shown in fig. 1, electronic equipment 10 includes：First power supply 11, second source 12, second source 13 ..., second electricity Source 1n (n >=3), balanced device 20, the controller 40 of voltage modulator 30 and first.Below, above-mentioned each component is carried out respectively Explanation.

As shown in fig. 1, first power supply 11 and at least multiple second electricity are included according to the electronic equipment 10 of the present invention Source (12,13 ..., 1n, wherein n >=3, hereinafter, second source (12,13 ..., 1n) be referred to as second source 1n, and If " there are qualifications in second source 1n ", " second source 1n " is intended to include meeting the restriction bar in the following description All second sources of part).Each power supply is connected with external power source and is that electronic equipment 10 is powered, and each power supply can call out Wake up and switch between state and resting state.Each second source 1n has respective priority, and the first power supply 11 has the One sleep threshold voltage Voff1 and the first threshold wake-up value voltage Von1, and the first sleep threshold voltage Voff1 calls out less than first Awake threshold voltage Von1, each second source 1n each have the second sleep threshold voltage Voff2 and the second threshold wake-up value voltage Von2, and the second sleep threshold voltage Voff2 is less than the second threshold wake-up value voltage Von2.

First power supply 11 and second source 1n can by civil power (such as 220V alternating current, 110V alternating current or Direct current) be converted to direct current suitable for electronic equipment 10, and for electronic equipment 10 each component (for example, memory, CPU Deng) power supply.In different types of electronic equipment 10, the first power supply 11 and second source 1n rated power there may be difference (for example, the rated power of the first power supply 11 is 1000W, second source 1n rated power is 600W), and actually make With period, the first power supply 11 and second source 1n power output also can be with running order second source 1n numbers Amount, electronic equipment 10 load etc. it is different and different.If in addition, do not explicitly point out, " the work of herein referred power supply State " is identical with " wake-up states " implication, refer both to power supply be electronic equipment 10 power state, simply herein in order to power supply Sleep operation is corresponding with wake operation, and the state of power supply is divided into " resting state " and " wake-up states ".

In addition, first power supply 11 is defined as into main power source according to the electronic equipment 10 of the present invention, and by second source 1n It is defined as from power supply.During electronic equipment 10 is run, main power source is in wake-up states to ensure the base of electronic equipment 10 all the time This operation, it can switch from power supply with the size of system load between wake-up states and resting state.In other words, in electricity During sub- equipment 10 is run, an a minimum of power supply (i.e. main power source) is in wake-up states, be up to n power supply (the i.e. first electricity Source 11 to second source 1n) it is in wake-up states.

Main power source from power supply with that can have a variety of set-up modes.For example, electronic equipment 10 controller (such as first control Device 40) address register is provided with, for preserving the address information of each power supply accessed.The controller is according to each electricity The address information in source carries out master/slave power supply setting to each power supply.So that electronic equipment 10 accesses four power supplys as an example, four power supplys Address information be respectively B0, B2, B4 and B6, the controller power supply corresponding to address information B0 can be set based on electricity Source, three power supplys corresponding to B2, B4 and B6 are arranged to from power supply.

Although a kind of set-up mode of master/slave power supply is exemplified above, but the present invention is not limited thereto, art technology Personnel, which can also be set up separately the power supply area that electronic equipment 10 accesses using known other appropriate set-up modes, is set to main power source With from power supply.For example, electronic equipment 10 can identify the rated power of each power supply accessed, distinguished according to rated power Main power source is set and from power supply.For example, electronic equipment 10 access four power supplys rated power be respectively 1000W, 600W, 600W and 600W, then electronic equipment 10 can by rated power be 1000W power supply be arranged to main power source, other three power supplys are set It is set to from power supply.

Each second source 1n has respective priority.By pre-setting priority, energy to each second source 1n It is enough when needing to carry out wake/sleep state handover operation to multiple second sources, according to the priority pre-set, in order Corresponding wake/sleep state handover operation is carried out to the multiple second source, so as to avoid in the prior art multiple the The dormancy simultaneously of two power supplys or the situation of wake-up.

Second source 1n priority can have a variety of set-up modes.For example, can with above set main power source with from Power supply similar mode sets second source 1n priority.Still so that electronic equipment 10 accesses four power supplys as an example, four electricity The address information in source is respectively B0, B2, B4 and B6, and power supply corresponding to wherein B0 is arranged to main power source, corresponding to B2, B4 and B6 Three power supplys are from power supply.Their priority can be correspondingly arranged respectively according to address B2, B4 and B6 from power supply, such as Described three are arranged to from the priority orders of power supply：Corresponding to B2 from corresponding to power supply ＞ B4 from corresponding to power supply ＞ B6 from Power supply.

Although a kind of set-up mode of second source 1n priority has been exemplified above, but the present invention is not limited thereto, Those skilled in the art can also be set using known other appropriate set-up modes to second source 1n priority Put.For example, priority orders can be set according to the difference of each second source 1n accessed rated power.User Can the priority orders of the second source 1n to being accessed be configured as needed during actual use electronic equipment 10. Below in conjunction with specific embodiment, priority to second source 1n and how the priority is utilized to carry out wake/sleep shape State handover operation is further described.

Each power supply is respectively provided with sleep threshold voltage and threshold wake-up value voltage.The sleep threshold voltage of each power supply is less than it Threshold wake-up value voltage.The sleep threshold voltage of each power supply and threshold wake-up value voltage can be considered as to the wake/sleep of the power supply The parameter of state handover operation.By by sleep threshold voltage and threshold wake-up value voltage respectively with another parameter (i.e. first voltage, It is described later on) it is compared, it can be determined that whether corresponding power supply is waken up or dormancy, if first voltage is less than or waited In sleep threshold voltage, then power supply can be switched to resting state from wake-up states, to reduce the power supply number in wake-up states Amount, so as to improve power-efficient；, can be by electricity in a dormant state if first voltage is more than or equal to threshold wake-up value voltage Source switches to wake-up states, to increase the number of power sources in wake-up states, so as to improve power-efficient.When first voltage between When between the respective threshold wake-up value voltage and sleep threshold of each power supply in wake-up states, it is believed that in wake-up shape The number of power sources of state is appropriate, i.e., power-efficient is ideal, without carrying out wake/sleep state handover operation again.

Due to the difference of the parameters such as the model of each power supply, rated power, their own sleep threshold voltage and wake-up Threshold voltage can also have differences.The sleep threshold voltage and threshold wake-up value voltage of each power supply can dispatch from the factory in electronic equipment 10 Shi Tongyi is configured, and can also be configured by user during actual use electronic equipment 10.Below in conjunction with specific reality Example is applied sleep threshold voltage and threshold wake-up value voltage is further described.

The first power supply 11 and second source 1n shown in Fig. 1 also include AC-DC converter (not shown) and peripheral circuit Deng component, because these components are the common knowledges of those skilled in the art, therefore do not influenceing to enter the technology of the present invention principle On the premise of row explanation, there is omitted herein the description to these components.

It is visible from the description above, electronic equipment 10 general power after 2000W drops to 1200W, electronic equipment The priority from power supply that 10 bases are pre-set, gradually decreases the quantity from power supply in wake-up states in order, so as to Avoid while make all situations for making main power source (rated power 1000W) individually carry 1200W power from power supply dormancy, i.e., Avoid system closedown.In addition, by the balanced progressive process of switching → equilibrium described above → switch again → again, it is also effective Power supply is avoided to shake repeatedly between working condition and resting state, and by gradually adjusting in running order power supply Quantity, in running order number of power sources is finally set to reach or close to ideal quantity, and average mark between these supplies With power, so as to realize the optimization to power-efficient.

Continue above-described situation, it is assumed that, now electronic equipment 10 starts the larger application of a power consumption, so that being The general power of system increases to 2000W from 1200W.

Next, balanced device 20 carries out balanced between the first power supply 11 and second source 14 to output current, the is formed One electric current I4, so as to realize 2000W power the mean allocation between two power supplys, make each power distribution 1000W.

Next, after voltage modulator 30 is according to the Current Voltage proportionate relationship and the equilibrium of equalised device 20 pre-set The first electric current I4 modulate the first voltage V4 of generation.In this case, it is assumed that first voltage V4 is 5V.

First controller 40 receives the wake-up transition signal from the first power supply 11, and judges second source 12 and Two power supplys 13 are in a dormant state.Then, the first controller 40 according to it is described wake-up transition signal and the priority come by Highest priority from power supply (i.e. second source 12) from dormancy in second source 12 and second source 13 in a dormant state State switches to wake-up states.

So far, the power supply in wake-up states is the first power supply 11, second source 12 and second source 14.It is assumed that now The power output of electronic equipment 10 does not change, still keeps 2000W.

Next, balanced device 20 is carried out between the first power supply 11, second source 12 and second source 14 to output current Equilibrium, the first electric current I5 is formed, so as to realize 2000W power the mean allocation between three power supplys, make each power supply point With 666W.

Next, after voltage modulator 30 is according to the Current Voltage proportionate relationship and the equilibrium of equalised device 20 pre-set First electric current I5 modulates the first voltage V5 of generation.In this case, it is assumed that first voltage V5 is 3.5V.

First controller 40 receives the wake-up transition signal from the first power supply 11, and judges only second source 13 In a dormant state.Then, second source 13 is switched to wake-up states by the control of the first controller 40 from resting state.

So far, the power supply in wake-up states is the first power supply 11, second source 12, second source 13 and second source 14.It is assumed that now the power output of electronic equipment 10 does not change, 2000W is still kept.

Next, balanced device 20 between the first power supply 11, second source 12, second source 13 and second source 14 to defeated Go out electric current and carry out balanced, form the first electric current I6, so as to realize 2000W power the mean allocation between four power supplys, make Each power distribution 500W.

Next, after voltage modulator 30 is according to the Current Voltage proportionate relationship and the equilibrium of equalised device 20 pre-set The first electric current I6 modulate the first voltage V6 of generation.In this case, it is assumed that first voltage V6 is 2.5V.

Next, second controller 111, second controller 121, second controller 131 and second controller 141 respectively will For first voltage V6 (2.5V) compared with Von (3V) and Voff (1.5V), the result drawn is that first voltage V6 (2.5V) is situated between In Von (3V) and Voff (1.5V).Second controller 111 does not make signal transmitting unit 50 send any turn to the first controller 40 State signal.Therefore, the first controller 40 is without wake/sleep state handover operation.

Next, when if electronic equipment 10 caused the power output to change due to the change of load, electronic equipment 10 will repeat above-mentioned wake/sleep state handover operation.The wake/sleep state handover operation be dynamic, real-time process, If the power output of electronic equipment 10 changes, electronic equipment 10 will be responded according to principles described above, Wake/sleep state switching is carried out to power supply, so as to adjust the quantity of the power supply in wake-up states, to reach optimization power supply effect The purpose of rate.

It is visible from the description above, electronic equipment 10 general power after 1200W rises to 2000W, electronic equipment 10 according to the priority from power supply pre-set, and gradually increase is in the quantity from power supply of wake-up states in order, passes through Switching → equilibrium → described above switches again → balanced progressive process again, power supply is effectively prevent in working condition and dormancy Shake between state, and by gradually adjusting in running order number of power sources, finally make in running order repeatedly Number of power sources reaches or close to ideal quantity, and mean allocation power between these supplies, so as to realize to power-efficient Optimization.

It is noted that the wake/sleep stateful switchover process of four power supplys of electronic equipment 10 described above is only It is exemplary, the present invention is not limited thereto.For example, example above was assumed within relative a period of time, electronic equipment 10 Power output keeps constant (being maintained at 1200W or 2000W), but in any one stage of above-mentioned example, electronic equipment 10 Power output change such as the change of load, correspondingly, the wake/sleep state of four power supplys accessed is cut Changing operation may be not as sequentially carrying out described in example above.For example, when electronic equipment 10 switches to second source 12 After resting state, the power output increase of electronic equipment 10, so that electronic equipment is in three power supplys (first of wake-up states Power supply 11, second source 13 and second source 14) pass through after the euqalizing current of balanced device 20, the modulation generation of voltage modulator 30 First voltage does not continue to carry out other wake/sleep states switching behaviour from power supply just between Von and Voff Make.

In addition, for the ease of description, in example above, four power supplys that electronic equipment 10 is accessed are assumed to phase Same power supply.But the present invention is not limited thereto, aforementioned four power supply can be different, such as the rated power of the first power supply 11 is 1000W, its sleep threshold voltage Voff1 is 1.5V, and its threshold wake-up value voltage Von1 is 3V；Three from power supply (second source 12, Second source 13 and second source 14) it is identical, their rated power are 600W, and their sleep threshold voltage Voff2 is 1V, their threshold wake-up value voltage Von2 is 2V.In this case, the wake/sleep state handover operation of each power supply with It is above-described similar.For example, if the power output of electronic equipment 10 is changed into 1200W from 2000W, balanced device 20 is at four Make each power distribution 300W after carrying out equilibrium to output current between power supply；The first voltage of the modulation generation of voltage modulator 30 It is 0.9V；Second controller 121, second controller 131 and second controller 141 judge three Voff2 (1V) from power supply It is all higher than first voltage (0.9V).Second controller 121, second controller 131 and second controller 141 send signal respectively Unit 50 sends dormancy transition signal to the first controller 40.First controller 40 is according to the dormancy transition signal and described By these three, the highest priority from power supply from power supply (i.e. second source 12) from wake-up states switches to dormancy to priority State.Although in addition, be shown as identical power supply from power supply by three above, but according to present invention original as described above Reason, three can also be different from power supply, and in this case, balanced first electric current, modulation generation first voltage, switching are called out The processes such as awake/resting state are similar with process described above, and those skilled in the art are referred to described above progress Understand.

Although present embodiment illustrates four power supplys, but aforementioned four power supply is only exemplary.People in the art In the situation for the power supply that principles described above can also be applied to other quantity by member, as long as the electricity that electronic equipment 10 is accessed Source quantity is more than or equal to three.

Although in example above, by balanced device 20, voltage modulator 30, second controller (111 to 141) and After the operation of first controller 40, corresponding wake/sleep state switching is carried out only for the second source of highest priority Operation, but the present invention is not limited thereto, and each wake/sleep state handover operation can also be directed to the of priority front two Two power supplys carry out wake/sleep state handover operation.For example, in the examples described above, when electronic equipment 10 is due to starting a work( Consume larger application so that system general power from 1200W increase to 2000W when, electronic equipment 10 can be simultaneously by second Power supply 12 and second source 13 switch to wake-up states from resting state.

It should also be noted that although foregoing illustrates change of the power from 2000W to 1200W and from 1200W to 2000W Change process, however shown change procedure be exemplary, of the invention electronic equipment in actual applications due to exist be Blanket insurance protection mechanism, system early warning mechanism etc., may not occur change procedure illustrated above.Therefore change procedure described above It is intended to instruct those skilled in the art or enlightened, and is understood not to limitation of the present invention.

For example it is assumed that it is current all from power supply (12,13 and 14) equal dormancy, because electronic equipment 10 starts one The larger application of power consumption, so that system load increases to 2000W, when the power output of main power source 11 gradually increases to 1300W When, the activation system protection mechanism of second controller 111 of main power source 11, signal transmitting unit 50 is sent to the first controller 40 3rd signal (i.e. urgent wake-up signal), and the first controller 40 according to the 3rd signal by three in a dormant state from electricity Source directly all wakes up, without euqalizing current described above and priority deterministic process, to avoid because the first power supply goes out System cut-off caused by existing failure.

According to the electronic equipment 10 of the first embodiment of the present invention by carrying out balanced, judgement to each electric power outputting current Meet condition carries out wake/sleep state handover operation, each from the priority of power supply, according to priority orders to power supply Said process is repeated after the switching of wake/sleep state, it is achieved thereby that preferential according to being pre-set for each power supply Level carries out wake/sleep state switching, avoids wake-up or the dormancy simultaneously of all power supplys of the condition that meets in the prior art The situation of the concussion of caused power work state, and for the difference of electronic equipment load, make to meet condition, it is appropriate The power work of quantity, so as to improve the power-efficient of electronic equipment under different loads.
