Abstract
The invention provides a design method for improving the power supply efficiency of a power supply system with multiple groups of power sources. One power consumption monitoring device in the power supply system with the power sources is used for sensing the actual power consumption of an electric system and selectively turns on or closes parts of power supply modules according to different power consumption, so that the power supply modules which are in operation always operate within 50%-60% of a load region range; and under the condition of not changing the power supply efficiency, the power sources operate within a higher power supply efficiency region selected from a power supply efficiency curve, i.e., the power sources select to supply power under 40%-80% of load, so that the power supply system with the power sources always operates under a state of 50%-60% of the best power supply efficiency. The method comprises the following specific steps of: detecting the power consumption of the whole system by virtue of power monitoring; then sending power consumption data to a data processing center; calculating the number of the power supply modules required to be used by virtue of the data processing center; and achieving the purpose of controlling the power supply modules through regulating the Enable level.
Description
Technical field
The present invention relates to computing machine or server power supply technique field.Specifically a kind of method for designing that in the multi-group power electric power system, improves power supplying efficiency; Mainly be in the large scale system of a lot of power module power supply of needs; Through monitoring the quantity that power consumption selects power module to open; Make it to be operated in higher efficient, broken through power supply itself because of the relatively poor limitation of the different efficient of load.
Background technology
Integrated, complicated along with electronic product, the trend of integration is more and more obvious, and electronic equipment becomes increasingly high to the requirement capability of power supply.So in the present power-supply system, electrorheological gets increasing.And be limited by the factor of electronic devices and components aspect manufacturing process and the characteristic of itself, and single FET, the anti-current value of key componentses such as inductance can't satisfy the demand of big electric current.In order to break through this bottleneck, develop flow equalize technology and the concatenation technology that power supply, so just provide the foundation for the common power supply of multi-group power.So a lot of great-power electronic products all is the multi-group power redundant power supply that adopts now.
The present energy-conservation most important parameter in the electronic product that becoming, how energy-conservation, become a very high demand of design electronic products scheme.The system configuration of electronic product with the same situation is set under, the efficient that improves power supply becomes energy-conservation the most effective scheme.The efficient of power supply under this demand, from original about 80% now to bring up to 90% or higher.But the raising of power-efficient also is limited, just means huge cost input and technical difficulty to the every raising one percentage point of 90% above efficient.
Summary of the invention
The purpose of this invention is to provide a kind of method for designing that in the multi-group power electric power system, improves power supplying efficiency.
The objective of the invention is to realize by following mode; Power consumption monitoring device in electric supply system; Through the actual power loss of detecting using electricity system, select to open or the closed portion power module according to different power consumption, make the power module of work always work in operation in the load interval range of 50%-60%; Under the situation that does not change power-efficient; Let power supply select the higher interval work of power supplying efficiency from the power-efficient curve, promptly power supply is selected 40%-80% load power supply down, makes electric supply system operation under the best power supplying efficiency state of 50%-60% all the time.
Concrete steps are following:
Detect the power consumption of total system through power monitoring; Power consumption data sends to data processing centre (DPC) then; Data processing centre (DPC) calculates the power module number of required use through calculating, and reaches the purpose of control switch of the power supply module then through the height of regulating the Enable level.
The invention has the beneficial effects as follows: the present invention is under the situation that does not change power-efficient, lets power supply select to be operated in itself higher interval of efficient, realizes the purpose that power supply is raised the efficiency.The power consumption monitoring device that the present invention increases, its real cost is very little concerning a plurality of power modules, and 90% above system all includes power detection device, has not so just had the increase of cost.And data processing module has each system the inside basically, and the write-in program content inserts input and output interfaces, that's all, do not increase any Material Cost.
Description of drawings
Fig. 1 is the schematic block circuit diagram of electric power system.
Embodiment
With reference to Figure of description to explanation at length below the work of the present invention.
Shown in accompanying drawing: under the situation that does not change power-efficient, let power supply select to be operated in itself higher interval of efficient.The power-efficient curve of a power supply generally is to be the highest at the 40%-80% of load, best efficient performance is arranged in about 50%.The present invention is exactly the actual power loss through detecting system; The actual power consumption of using is divided by 50% of the nominal load of every group of power module; Draw then should the opening power module number; The power module of work is always worked in the load interval range about 50%, make it to always work in a best efficient state, should be able to raise the efficiency about 2% like this.
Detect the power consumption of total system through power monitoring; Power consumption data sends to data processing centre (DPC) then; Data processing centre (DPC) calculates the power module number of required use through calculating, and reaches the purpose of control switch of the power supply module then through the height of regulating the Enable level.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
