For technical matters, technical scheme and advantage that the embodiment of the invention will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
In the process that realizes the embodiment of the invention, the inventor finds that by the load of analysis Switching Power Supply and the relation of efficient Switching Power Supply is most effective when load is 40%-80%, and efficient is lower under all the other situations.Yet the power supply module PSU of a plurality of parallel connections of existing redundant power is equally loaded.The advantage that adopts equally loaded is that design is easy, and shortcoming is to make efficient reach the highest.
Fig. 2 is the schematic flow sheet of the redundant power control method of the embodiment of the invention.In this embodiment, redundant power comprises the power supply module PSU of a plurality of parallel connections, and these a plurality of PSU all are connected with load.As Fig. 2, the redundant power control method of the embodiment of the invention comprises the steps:
Exemplarily, above-mentioned predetermined allocation scheme is: under the identical situation of output general power, from predefined all allocation scheme, the output power that chooses in advance is less than one or more allocation scheme of predetermined threshold.Exemplarily, under the identical situation of output general power, can predefined all allocation scheme in, the lower plurality of distribution fraction of input general power is set to be scheduled to allocation scheme.
Preferably, above-mentioned predetermined allocation scheme is the optimal allocation mode under current output general power, and wherein, this optimal allocation mode is: under the identical situation of output general power, in predefined all allocation scheme, the minimum allocation scheme of input general power.
In the embodiments of the invention, when distributing the output power of each power supply module PSU by the lower predetermined allocation scheme of power input, especially, when distributing the output power of each PSU by the minimum optimal allocation mode of power input, the energy that redundant power input general power when producing identical output power is lower, expend when producing identical output power still less, thereby have the effect of energy saving.
Preferably, can set in advance the predetermined allocation scheme of each power supply module output power under output general power and this output general power, exemplarily, as the optimal allocation mode, between corresponding relation, exemplarily, this corresponding relation can be stored in advance in the mode of form, after determining the current output general power of redundant power, by tabling look-up, can obtain under this output general power the predetermined distribution module of the output power of each PSU, exemplarily, as the optimal allocation mode.Exemplarily, table 1 has provided a redundant power that comprises 3 PSU under the situation of difference output general power, and the optimal allocation mode of the output power of each PSU is under this optimal allocation mode, the input general power of redundant power is minimum, and promptly the output efficiency of redundant power is the highest.
| The output general power (watt) | |
|
PSU 3 output powers (watt) |
| 300 | 80 | 120 | 100 |
| 500 | 150 | 150 | 200 |
| ... | ... | ... | ... |
Table 1
Exemplarily, in this embodiment, if the output general power that obtains is 500 watts, and the output power of PSU 1 is 100 watts, the output power of PSU 2 is 100 watts, the output power of PSU 3 is 300 watts, then by question blank 1, judge, the allocation scheme of the output power of current each PSU is not best allocation scheme, then readjusts the output power of each PSU according to the allocation scheme in the table 1, particularly, the output power of PSU1 is adjusted into 150 watts, the output power of PSU 2 is adjusted into 150 watts, the output power of PSU 3 is adjusted into 200 watts.
Last table 1 is an example just, and numerical value wherein is exemplary providing.In specific implementation, for the possible output general power of a certain redundant power, and for a certain concrete output general power, and the value that under this output general power, can make redundant power import the output power of each minimum PSU of general power can precompute by test, and the value that will calculate inserts in the similar above-mentioned table, so that inquire about application in concrete control procedure.
Certainly, for same output general power, also can list two or more predetermined allocation scheme in the last table.Exemplarily, for the situation of two kinds of predetermined allocation scheme, these two kinds of predetermined allocation scheme can be: under this output general power, output power is minimum and time low these two kinds of allocation scheme.Similarly,, can be that this exports under general power, the minimum plurality of distribution mode of input general power for the situation of two or more predetermined allocation scheme.For predetermined allocation scheme is multiple situation, in the whether identical step of the output power allocation scheme of judging current each PSU with predetermined allocation scheme, judge one by one, have only when the output power allocation scheme of current each PSU and all predetermined allocation scheme not simultaneously, ability execution in step 203, and situation for multiple predetermined allocation scheme, can choose any one kind of them from the plurality of distribution mode that allocation scheme is redistributed or therefrom select minimum a kind of of input general power, or determine priority for above-mentioned multiple predetermined allocation scheme in advance, redistribute by the allocation scheme of optimum.

Be that the optimal allocation mode is that example describes with predetermined allocation scheme below.Predetermined allocation scheme does not repeat them here for the situation of other less allocation scheme of input general power is similar.
Illustrate, as concrete two identical PSU1 of redundant power and PSU2, the output general power is 200 watts, and when the power that distributes is accurate to watt-hour, all allocation scheme of then predefined exhaustive PSU1 and PSU2 comprise following 201 kinds:

PSU1＝99，PSU2＝101，
PSU1＝100，PSU2＝100；
PSU2＝0，PSU1＝200；
PSU2＝1，PSU1＝199；
PSU2＝2，PSU1＝198；
PSU2＝99，PSU1＝101。

Exemplarily, can carry out above-mentioned exhaustive operation by processor such as the CPU that is arranged in the control device.
Exemplarily, the input general power of the redundant power in above-mentioned all allocation scheme under arbitrary allocation scheme can be passed through: calculate the power input of each PSU under this allocation scheme, and each PSU power input sum of calculating obtains.Particularly, can set in advance the load of each PSU and the corresponding relation between the efficient, and determine the output efficiency of each PSU under current output situation according to the output power of this corresponding relation and current each PSU, then, obtain the power input of each PSU under current output situation by the ratio that calculates between each PSU and the current separately output efficiency, calculate again each PSU power input and promptly obtain the input general power of redundant power under current allocation scheme.Wherein, the load of each PSU and the corresponding relation between the efficient can set in advance in the control device of redundant power.
Preferably, after the output power of each PSU of redundant power is redistributed, also comprise: according to the life situations of each PSU module, the output power of each PSU module is adjusted in timesharing.Do like this can balanced each PSU module life-span, make each PSU timesharing to be in high efficiency duty.For example, when redundant power PSU comprises two identical PSU1 and PSU2, as according to the precalculated or exhaustive result who goes out being 80 watts of outputs among two PSU, the output total efficiency of output 120 watt-hour redundant powers is the highest, then setting makes PSU1 be output as 80 watts as control device, make PSU2 be output as 120 watts, then in redundant power work preset time section for example after one month, the output of PSU2 can be adjusted into 80 watts, the output of PSU1 is adjusted into 120 watts, and can be after redundant power be worked one month like this, the output of adjusting back PSU1 again is adjusted into 80 watts, the output of PSU2 is adjusted into 120 watts, and such adjustment can be carried out once in every month.Certainly, the time cycle of concrete adjustment can be provided with as required.And the time cycle of this adjustment can set in advance in control device.
