Fig. 3 (a) is to be the measured corresponding curve map with efficient of output current that comes out of example with the polyphase source supply device that two power conversion unit are finished.
Fig. 3 (b) is to be the measured corresponding curve map with efficient of output current that comes out of example with the polyphase source supply device that three power conversion unit are finished.
Fig. 4 is that the power supply that the present invention develops is out supplied the second preferred embodiment steps flow chart synoptic diagram of method of adjustment.
Embodiment
See also Fig. 1, it is the computer system functions block schematic diagram that can use the inventive method, consist predominantly of a computer system 10 and a polyphase source supply device 11, wherein polyphase source supply device 11 is to supply suitable output current according to the duty of computer system 10 to use for computer system 10.And include a plurality of power conversion unit 111-11n that can independent open and close in the polyphase source supply device 11 of the present invention, therefore power conversion unit 111-11n can accept the control of computer system 10 and changes the quantity that it is activated, and then changes the power supply conversion efficiency of polyphase source supply device 11.
See also Fig. 2, its power supply that is the present invention develops is out supplied the first preferred embodiment steps flow chart synoptic diagram of method of adjustment.At first, computer system 10 is just detected the size (step S21) that this polyphase source supply device 11 is supplied to an output current Io of this computer system 10 every a schedule time (step S20), enable the quantity (step S22) of a plurality of power conversion unit 111-11n in this polyphase source supply device 11 then according to the numerical value change adjustment of this output current Io, and then dynamically adjust polyphase source supply device 11 and reach the optimized purpose of power supply conversion efficiency.
See also Fig. 3 (a) again, it is to be the measured corresponding curve map with efficient of output current that comes out of example with the polyphase source supply device that two power conversion unit are finished, on behalf of single power conversion unit, two curves wherein being drawn enable (hereinafter to be referred as single-phase mode) and two corresponding curves with efficient of output current that power conversion unit is all enabled (hereinafter to be referred as the two-phase pattern) respectively, and can know by figure and to find out, in the High Output Current district of high capacity, the efficient of two-phase pattern is good than the efficient of single-phase mode really, but in the low output current district of low load, then be that the efficient of single-phase mode is preferable.And example can be observed out thus, two curves are located to interlock about 10 amperes, therefore, the numerical value that detects output current when computer system 10 just operates in the two-phase pattern with the polyphase source supply device more than or equal to threshold value 10 ampere-hours, otherwise, the numerical value that detects output current when computer system 10 is less than threshold value 10 ampere-hours, just the polyphase source supply device is operated in single-phase mode, so will effectively with the power supply conversion efficiency optimization, and then reach the effect of province's energy.
See also Fig. 3 (b) again, it is to be the measured corresponding curve map with efficient of output current that comes out of example with the polyphase source supply device that three power conversion unit are finished, three curves wherein being drawn are to represent single power conversion unit to enable (hereinafter to be referred as single-phase mode) respectively, two power conversion unit are enabled (hereinafter to be referred as the two-phase pattern) and three corresponding curves with efficient of output current that power conversion unit is all enabled (hereinafter to be referred as three facies models), can know by figure two cross-point P1 finding out three curve produced and P2 the corresponding first electric current threshold value I1 and the second electric current threshold value I2 that goes out, output current can be divided into three districts: the High Output Current district, middle output current district and low output current district.Therefore, the numerical value that detects output current when computer system 10 is during more than or equal to the second electric current threshold value I2, just the polyphase source supply device is operated in three facies models, and the numerical value that detects output current when computer system 10 is during less than the second electric current threshold value I2 but more than or equal to the first electric current threshold value I1, just the polyphase source supply device is operated in the two-phase pattern, as for the numerical value that detects output current when computer system 10 during less than the first electric current threshold value I1, just the polyphase source supply device is operated in single-phase mode, so the power supply conversion efficiency of the polyphase source supply device that also can effectively three power conversion unit be finished is finished optimization, and then reaches the effect of province's energy.The rest may be inferred, even the also available said method of polyphase source supply device that four more a plurality of power conversion unit are finished carries out optimization, therefore no longer given unnecessary details.
In addition, carry out the judgement of mode switch, can also utilize detecting, and then make the judgement of mode switch the various load conditions of computer system 10 itself except detecting the output current Io that this polyphase source supply device 11 is supplied to this computer system 10.For instance, Fig. 4 is that the power supply that the present invention develops is out supplied the second preferred embodiment steps flow chart synoptic diagram of method of adjustment, at first, computer system 10 is every the just residing image processing pattern of display card (step S41) of Auto-Sensing self of a schedule time (step S40), for example be to be in to need the 3D of high-current consumption image processing pattern, or be in the 2D image processing pattern of general power consumption, enable the quantity (step S42) of a plurality of power conversion unit 111-11n in this polyphase source supply device 11 then according to the variation adjustment of image processing pattern, and then dynamically adjust polyphase source supply device 11 and reach the optimized purpose of power supply conversion efficiency.Certainly, except the image processing pattern, other pattern also can be relevant with the size of load condition in addition, power supply status of CPU (central processing unit) (power state) or the like for example, can bring the reference of being used as the power consumption size, and then adjust the quantity of enabling a plurality of power conversion unit 111-11n in this polyphase source supply device 11.Give an example again, if the quantity of power conversion unit is 8, and the power supply status of CPU (central processing unit) (power state) is divided into 4 kinds, that just can be divided into polyphase source supply device 11 2,4,6 and 8 four patterns such as power conversion unit of opening, in order to correspond to 4 kinds of power supply statuss (power state) of CPU (central processing unit), so will also can allow power supply conversion efficiency comparatively near the optimization result, and then improve the shortcoming of above-mentioned technological means, reach development fundamental purpose of the present invention.
So the present invention not only really belongs to innovation on technological thought, and possesses known classic method above-mentioned multinomial effect can't be obtained, fully meets novelty and creationary legal patent of invention condition, so file an application in accordance with the law.Right the present invention can do a little change and retouching by the personage who has the knack of this technology, right neither disengaging claim protection domain of the present invention.
