Embodiments of the present application are described below with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic flowchart of power management methods according to an embodiment of the present invention, where the method is applied to an information technology IT system, and the IT system includes a th group of power supplies and a second group of power supplies, and includes the following steps:
s101, in the normal operation of the IT system, a power management device acquires the rated power of the th group of power supplies, the rated power of the second group of power supplies and the current power of the IT system.
S102, if the current power of the IT system is less than or equal to the percent of the rated power of any groups of power supplies in the two groups of power supplies, the power management device turns off a current sharing signal between the group of power supplies and the second group of power supplies, and increases the output voltage of the group of power supplies and decreases the output voltage of the second group of power supplies.
The th percentage may be, for example, 20%, 30%, 40%, 50%, 55%, 60% or other values, and preferably 50%.
In the above step S101, in the normal operation of the IT system, the power management device first sets the rated power of all power sources included in the th group power source, the rated power of all power sources included in the second group power source, the current power of all power sources included in the th group power source, and the current power of all power sources included in the second group power source, where the rated power of the th group power source is the sum of the rated powers of all power sources included in the th group power source, the rated power of the second group power source is the sum of the rated powers of all power sources included in the second group power source, and the current power of the IT system is the sum of the current power of all power sources included in the th group power source and the sum of the current power of all power sources included in the second group power source.
For example, assuming that the rated power of the th group of power sources is 50W, the rated power of the second group of power sources is 60W, the current power of the IT system is 20W, and the th percentage is 50%, IT can be seen that the current power 20W of the IT system is less than the rated power 50W 25W of the th group of power sources and the rated power 60W 50% 30W of the second group of power sources.
IT can be seen that, in normal operation of the IT system, if the current power of the IT system is less than or equal to the percent of the rated power of any groups of power supplies in the two groups of power supplies, the power management device closes the current sharing signal between the group of power supplies and the second group of power supplies, and increases the output voltage of the group of power supplies and decreases the output voltage of the second group of power supplies, so that only the group of power supplies supply the IT system, and further the service efficiency of the power supplies is improved, in addition, the scheme does not need to close a certain group of power supplies, and only needs to decrease the output voltage of a certain group of power supplies, so that when the group of power supplies for supplying power fails or input power fails, another group of power supplies can still supply power for the whole system, and further the stability of services is ensured.
For example, when the group of power supplies includes N power supplies, the second group of power supplies also includes N power supplies, where N is an integer greater than or equal to 1.
In other words, after the current sharing signal between the th group of power supplies and the second group of power supplies is turned off, then the output voltages of the th group of power supplies and the second group of power supplies are adjusted, or after the current sharing signal between the th group of power supplies and the second group of power supplies is turned on, the output voltages of the th group of power supplies and the second group of power supplies are within the output voltage range when the IT system normally works, so that when the th group of power supplies fails or input power failure occurs, the output power supplies of the second group of power supplies can support the IT system to work, and further, the stability of services is ensured.
For example, assuming that the power supply of the st group comprises power supply 0 and power supply 1, the power supply of the second group comprises power supply 2 and power supply 3, and after the output voltage of the st group is increased and the output voltage of the second group is decreased, the output voltage after the current sharing of power supply 0 and power supply 1 is higher than the output voltage of power supply 2 and power supply 3.
Optionally, the method further includes:
if the current system power of the IT system is more than the percent of the rated power of any groups of power supplies in the two groups of power supplies, the power supply management device starts a current sharing signal between the group of power supplies and the second group of power supplies so that the output voltages of the group of power supplies and the second group of power supplies are adjusted to be within a preset output voltage range.
Optionally, the th group of power supplies comprises a plurality of power supplies, and after the power management device adjusts the output voltage of the th group of power supplies and adjusts the output power of the second group of power supplies, the method further comprises:
and if the current power of the th group of power supplies is less than or equal to a second percentage of the rated power of the th group of power supplies, the power management device closes the current sharing signal of any power supply in the plurality of power supplies and reduces the output voltage of any power supply.
The second percentage may be, for example, 20%, 30%, 40%, 50%, 55%, 60% or another value, and preferably 50%.
The specific step of the power management device obtaining the current power of the th group of power sources is that the power management device first obtains the current power of all power sources included in the th group of power sources, and the current power of the th group of power sources is the sum of the current power of all power sources included in the th group of power sources.
For example, assuming that the rated power of the th group power supply is 50W, the current power of the th group power supply is 20W, and the th percentage is 50%, it can be seen that the current power of the th group power supply is 20W, 50W × 50% or 25W, which is less than the rated power of the th group power supply.
Optionally, the method further includes:
if the current power of the th group of power supplies is greater than a second percentage of the rated power of the th group of power supplies, turning on a current sharing signal of an offline power supply of the th group of power supplies, and increasing the output voltage of the offline power supply.

If the current power of the IT system is greater than the rated power of any power supplies in the IT system, step S206 is executed.
And S204, the power management device turns off a current sharing signal between the power supply 0 and the power supply 1. A schematic diagram of turning off the current sharing signal between the power supply 0 and the power supply 1 is shown in fig. 3.
S205, the power management device increases the output voltage of the power supply 0 and decreases the output voltage of the power supply 1. After step S205 is executed, step S201 is executed.
S206, the power management device starts a current sharing signal between the power supply 0 and the power supply 1, so that the output voltages of the power supply 0 and the power supply 1 are adjusted to be within a preset output voltage range. After step S206 is executed, step S201 is executed.
