Be to be the explanation that example is carried out in Fig. 2, but its number can be arbitrarily more than or equal to 2 integer with 3 power supply modules and 2 power detection module.
Certainly, when these at least two power supply modules are identical power supply module, the priority of power supply module can be set, select power supply module according to priority.
As 3 power supply modules, selecting wherein 1 during for all power consumption subsystems power supplies, the power supply module that preferred priority is the highest is powered.
Certainly, starting each time all needs initially to power, so the redundant power supply equipment of the embodiment of the invention also comprises:
The initial switch control module is used for controlling described switch module according to an initial annexation when starting, and makes described at least two power supply modules and described at least two power detection module form initial connected mode.
In specific embodiments of the invention, this switch module can be number shown in Figure 2 and the same number of a plurality of one-to-many switches of described at least two power supply modules, also can be the switch one to one that forms between each power supply module and each power detection module.
Be elaborated below in conjunction with the equipment of real example to first embodiment of the invention.
The number of supposing power supply module is two, be respectively first power supply module and second source supply module, and the power detection module number is two, is respectively first power detection module and second power detection module.
At first need to obtain two the power supply module loads separately and the corresponding relation of delivery efficiency, promptly obtain curve shown in Figure 1.
Under actual working state, power detection module detects the current actual demand power of the subsystem corresponding with it in real time, and sends to computing module.
Simultaneously, the connected mode between all possible power supply module and the power detection module is as follows, comprises 5 kinds of modes:
First power supply module is connected with second power detection module with first power detection module, and the second source supply module is power output not;
The second source supply module is connected with second power detection module with first power detection module, and first power supply module is power output not;
First power supply module is connected with first power detection module, and the second source supply module is connected with second power detection module;
The second source supply module is connected with first power detection module, and first power supply module is connected with second power detection module;
First power supply module all is connected with second power detection module with first power detection module with the second source supply module.
The current actual demand power of supposing the subsystem that the detection of current first power detection module and second power detection module obtains is respectively X and Y;
At this moment, calculate the total losses power of the power supply module under the various connected modes respectively.
With the third connected mode is the calculating of example explanation total losses power.
Because first power supply module is connected with first power detection module, the second source supply module is connected with second power detection module, so at first according to the load of first power supply module and the corresponding relation of delivery efficiency, delivery efficiency when finding out load and being X, be assumed to A%, the power loss that can obtain first power supply module this moment is 100X/A, and then according to the load of second source supply module and the corresponding relation of delivery efficiency, delivery efficiency when finding out load and being Y, be assumed to B%, the power loss that can obtain first power supply module this moment is 100Y/B, and obtaining total loss power at last is 100X/A+100Y/B.
Can obtain the pairing total loss power of various connected modes according to processing mode same as described above.
After this, therefrom select the connected mode of total loss power minimum, be assumed to the second source supply module and be connected with first power detection module, first power supply module is connected with second power detection module.
At this moment, control module makes the second source supply module be connected with first power detection module by the conducting of the switch between control power supply module and the power detection module, and first power supply module is connected with second power detection module.
Therefore, be operated under this connected mode, under the certain situation of power output, total loss power minimum has improved the utilance of electric energy, has reached purpose of energy saving.
Below with one more real example describe.
The maximum power of supposing the first power consumption subsystem and the second power consumption subsystem all is 100W, but be relatively independent system between two systems, the impossible realtime uniform of the state of operation, the power of the first power consumption subsystem may be 80W at this moment in other words, and the power of the second power consumption subsystem is 20W only, and may just change to 20W at power consumption at following a moment first subsystem, and the second power consumption subsystem has become 50W.
At this moment, under the situation of energy supply respectively, be example with curve shown in Figure 1, the gross output of first power supply module reaches 20W/0.74=27W, the loss of 7W is arranged, and the second source supply module is 50W/0.83=60W, and the loss of 10W is arranged, and the loss of 17W is just arranged altogether, if this moment, one of them power supply module quit work, have only a power supply module power supply, then gross output is 70W/0.82=85W, has only the loss of 15W.
Particularly two power consumption subsystems are all under the situation of low load, when for example the two all is 10W, this moment, gross output was 2*10/0.54=37W, loss is 17W, if only use the power supply of single power supply then be 20/0.74=27W, loss this moment has only 7W, and the efficient of Ti Gaoing has reduced loss greatly.
Yet, when considering all possible connected mode, can not improved connection not need to handle for some, current actual demand power as the first power consumption subsystem is 70W, and the current actual demand power of the second power consumption subsystem is 90W, at this moment, first power supply module and second source supply module all are operated in from the some work far away of the most effective point of system load, therefore the necessity that does not have combination, set the electric mode and be: power supply 1 and power supply 2 are given system 1 and system's 2 power supplies respectively.
In the first embodiment of the present invention, this power detection module can be to work in following 2 kinds of mode of operations:
Mode of operation one, periodicity detect, and testing result is sent to computing unit, and its cycle can be set according to actual needs by the user;
The power detection module of mode of operation one comprises:
Detecting unit is used for the current actual demand power that periodicity detects corresponding subsystem, generates a testing result;
Transmitting element is used for described testing result is sent to described switch control module.
Mode of operation two, be reference with the testing result of a future position, during greater than some pre-set threshold, ability sends to computing unit at the absolute value of the testing result of pre-determined number continuously and the difference of the testing result of reference prediction point.
The power detection module of mode of operation two comprises:
