| The output gross power (watt) | |
|
PSU 3 power outputs (watt) |
| 300 | 80 | 120 | 100 |
| 500 | 150 | 150 | 200 |
| ... | ... | ... | ... |
Table 1
Exemplarily, in this embodiment, if the output gross power that obtains is 500 watts, and the power output of PSU 1 is 100 watts, the power output of PSU 2 is 100 watts, the power output of PSU 3 is 300 watts, then by question blank 1, judge, the method for salary distribution of the power output of current each PSU is not the best method of salary distribution, then readjusts the power output of each PSU according to the method for salary distribution in the table 1, particularly, the power output of PSU1 is adjusted into 150 watts, the power output of PSU 2 is adjusted into 150 watts, the power output 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 gross power of a certain redundant power, and for a certain concrete output gross power, and the value that under this output gross power, can make redundant power import the power output of each minimum PSU of gross 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.
