For example, the required operating power of the described electronic equipment that gets access to is 100W, and effectively the number of power module 201 is 1, and the power that each described power module 201 can provide is 90W.105 of described first computing modules can calculate the current power module 201 that needs to increase according to the above-mentioned data that get access to.

In addition, when the described power supply module 200 current electrical loads that can provide are provided described comparison module 103 greater than the required electrical load of described electronic equipment, described electric power controller 100 can also calculate the number of the current power module that can reduce 201, with user-friendly, reduce system cost.

Be illustrated in figure 4 as a structural representation again of the electric power controller of the embodiment of the invention, on the basis of embodiment shown in Figure 2, described electric power controller 100 also comprises:

Second computing module 107, be used at described comparative result for the described power supply module 200 current electrical loads that can provide during greater than the required electrical load of described electronic equipment, according to the electrical load that number and each described power module 201 of the required electrical load of described electronic equipment, described effective power module 201 can provide, calculate the number of the current power module that can reduce 201.

The 3rd reminding module 108 is used to point out the number of the described current power module that can reduce 201.At this moment, the user can reduce power module 201 according to prompting, and the power module 201 of corresponding number is extracted, and promptly carries out the operation of pulling out of power module 201.

The method of for example how above-mentioned second computing module 107 being calculated the number of the current power module that can reduce 201 describes below.

Suppose that the required power of described electronic equipment that gets access to is 150W, the number of described effective power module 201 is 3, and the power that each described power module 201 can provide is 100W;

The method that described second computing module 107 calculates the number of the current power module that can reduce 201 mainly may further comprise the steps:

Step 1: obtain described power supply module 200 in that the power that can provide behind the power module 201 is provided, as first power; For example, described first power is: 3 * 100-100=200W;

Step 2: the power (150W) that described first power (200W) and described electronic equipment is required compares, and obtains a comparative result.At described comparative result is that described first power (200W) is more than or equal to the required power of described electronic equipment (150W), show described power supply module 200 reduce a power module 201 backs the power that can provide, still can satisfy the required power of described electronic equipment, execution in step three; At described comparative result when being described first power less than the required power of described electronic equipment, show described power supply module 200 reduce a power module 201 backs the power that can provide, can't satisfy the required power of described electronic equipment, therefore, the number that then can determine the current power module that can reduce 201 is 0.

Step 3: obtain current described power supply module 200 once more the power that can provide behind the power module 201 is being provided, as described first power, at this moment, described first power is: 3 * 100-100-100=100W;

Step 4: the power (150W) that described first power (100W) and described electronic equipment is required compares, and obtains a comparative result;

Step 5: described comparative result is that described first power (100W) is less than the required power of described electronic equipment (150W), show that then described power supply module 200 reduces the power that 2 power modules, 201 backs are provided, and can not satisfy the required power of described electronic equipment; Therefore, can determine that then the number of the power module 201 that can reduce is 1, promptly the user is current can reduce by 1 power module 201.

Certainly, described second computing module 107 also can adopt additive method to calculate the number of the current power module that can reduce 201, describes in detail no longer one by one at this.

The electric power controller that provides by the foregoing description, at comparative result for the current electrical load that can provide of power supply module during greater than the required electrical load of electronic equipment, can determine the number of the current power module that can reduce, thereby can reduce the outfit number of power module, reduce system cost.

In order to prevent that power module in the power supply module from breaking down and can't continue power supply, cause the consumer data to lose even damage, described power supply module preferably needs to have redundancy feature.Cardinal principle with redundancy feature provides at least two power modules, when operate as normal, all power modules are provided by the power supply that provides to consumer, but when one of them power module breaks down and can't power, can continue to provide power supply by other power modules.Suppose, each power module maximum can provide the power of 200W, in the required electrical load of consumer is 160W, only need insert two power modules in the redundancy power supply module this moment, just can provide redundancy feature, during operate as normal, each power module provides the power of 80W, when one of them power module broke down and can't power, another power module can continue to provide the power of 160W.In the required electrical load of consumer is 390W, needs to insert three power modules in the redundancy power supply module, just can provide redundancy feature, and only allow a power module and break down this moment.If insert four power modules in the redundancy power supply module, then not only can provide redundancy feature, break down simultaneously but also allow two power modules.

In the foregoing description, described electric power controller 100 can calculate the number of the current power module that can reduce 201, thereby can reduce system cost.Yet, after reducing power module 201, described power supply module 200 but possibly can't be supported redundancy feature, when promptly a power module 201 can't be worked therein, the electrical load that other power modules 201 are provided, can't satisfy the required electrical load of described electronic equipment, thereby cause the loss of data of described electronic equipment, even can cause electronic equipment to damage.Therefore, in order to improve the system performance of electronic equipment, when reducing system cost, also need to guarantee the redundancy feature of power supply module.

Be illustrated in figure 5 as the another structural representation of the electric power controller of the embodiment of the invention, on the basis of embodiment shown in Figure 2, described electric power controller 100 also comprises:

The 3rd computing module 109, be used at described comparative result for the described power supply module 200 current electrical loads that can provide during greater than the required electrical load of described electronic equipment, the electrical load that can provide according to the required electrical load of described electronic equipment and each described power module 201, the number of required power module 201 when calculating described power supply module 200 and can provide redundancy feature, and number poor of required power module 201 when calculating the number of described effective power module 201 and described power supply module 200 and can provide redundancy feature, obtain can providing the number of the current power module that can reduce 201 under the condition of redundancy feature at described power supply module 200.

The 4th reminding module 110 is used to point out the number of the current power module that can reduce 201 under the described condition that redundancy feature can be provided at described power supply module 200.

For example can provide the method for the number of the current power module that can reduce 201 under the condition of redundancy feature to be elaborated to how calculating at described power supply module 200 below, be example with power as above-mentioned electrical load still in the embodiment of the invention.

Suppose that the required power of described electronic equipment that gets access to is 200W, the number of described effective power module 201 is 4, and the power that each described power module 201 can provide is 100W.

Can be by the following method, calculate the number that the current power module that can reduce 201 under the condition of redundancy feature can be provided at described power supply module 200.

The electrical load that described electronic equipment is required (200W) compares with the electrical load (100W) that each described power module 201 can provide, from comparative result, need 3 power modules 201 just can provide redundancy feature at least at described power supply module 200.If 2 power modules 201 are only arranged in the described power supply module 200, when one of them power module 201 can't be worked, the electrical load (100W) that another power module 201 can provide, can't satisfy the required electrical load of electronic equipment (200W), can not provide redundancy feature when therefore, in the described power supply module 200 2 power modules 201 only being arranged.If have 3 power modules 201 in the described power supply module 200, when one of them power module 201 can't be worked, the electrical load that other 2 power modules 201 can provide (100W * 2=200W), can satisfy the required electrical load of electronic equipment (200W), therefore, need 3 power modules 201 just can provide redundancy feature in the described power supply module 200 at least.

At this moment, guaranteeing that described power supply module 200 can provide under the condition of redundancy feature, the number of the current power module that can reduce 201 equals: when the number of the power module 201 of described power supply module 200 current configurations and described power supply module 200 can provide redundancy feature poor (4-3=1) of the number of required power module.

If the number of the power module 201 of described power supply module 200 current configurations is 3, then guaranteeing that described power supply module 200 can provide under the condition of redundancy feature, the number of the current power module that can reduce 201 equals: 3-3=0, promptly in order to guarantee that described power supply module 200 can provide redundancy feature, the current number that can not reduce power module 201.
