Abstract

A first operating condition and a second operating condition at a power supply unit (PSU) are determined at a first time. A power conversion efficiency of the PSU is determined at the first time. A first entry at a power conversion efficiency profile is generated, the first entry associating the first power conversion efficiency with the first operating condition and the second operating condition.

First claim

What is claimed is:

1 . A method comprising:
determining a first operating condition at a power supply unit (PSU) at a first time; determining a second operating condition at the PSU at the first time; determining a power conversion efficiency of the PSU at the first time; and generating a first entry at a power conversion efficiency profile, the first entry associating the power conversion efficiency with the first operating condition and with the second operating condition.

2 . The method of claim 1 , wherein the first operating condition is an amount of power provided by the PSU.

3 . The method of claim 1 , wherein the second operating condition is a temperature at the PSU.

4 . The method of claim 1 , wherein the first time is determined based on a timer arranged to periodically indicate that a predetermined amount of time has elapsed.

5 . The method of claim 1 , wherein the first time is determined based on determining that a change in a value of the first operating condition exceeds a first threshold.

6 . The method of claim 1 , further comprising:
providing a plurality of power supply units including the first PSU, each unit associated with a corresponding power conversion efficiency profile; and engaging operation of the first PSU based on the power conversion efficiency profiles.

7 . The method of claim 1 , further comprising storing the power conversion efficiency profile at a data storage device at an information handling system.

8 . The method of claim 1 , further comprising storing the power conversion efficiency profile at a data storage device at the PSU.

9 . The method of claim 1 , wherein determining the first operating condition further comprises determining an average value of the first operating condition over a predetermined period of time.

10 . A system comprising:
a data processing device; a power supply unit (PSU) to provide power to the data processing device; a power management unit coupled to the PSU, the power management unit to:
determine a first operating condition at a power supply unit (PSU) at a first time;
determine a second operating condition at the PSU at the first time;
determine a power conversion efficiency of the PSU at the first time; and
generate a first entry at a power conversion efficiency profile, the first entry associating the power conversion efficiency with the first operating condition and with the second operating condition.

11 . The system of claim 10 , wherein the first operating condition is an amount of power provided by the PSU.

12 . The system of claim 10 , wherein the second operating condition is a temperature at the PSU.

13 . The system of claim 10 , wherein the first time is determined based on a timer arranged to periodically indicate that a predetermined amount of time has elapsed.

14 . The system of claim 10 , wherein the first time is determined based on determining that a change in a value of the first operating condition exceeds a first threshold.

15 . The system of claim 10 , further comprising:
a plurality of power supply units, each unit associated with a corresponding power conversion efficiency profile; wherein the power management unit is further to engage operation of the first PSU based on the power conversion efficiency profiles.

16 . The system of claim 10 , wherein the power management unit is further to store the power conversion efficiency profile at a data storage device at a data storage device at the PSU.

17 . A computer-readable medium storing a software program, the software program comprising a set of instructions to manipulate at least one processor to:
determine a first operating condition at a power supply unit (PSU) at a first time; determine a second operating condition at the PSU at the first time; determine a power conversion efficiency of the PSU at the first time; and generate a first entry at a power conversion efficiency profile, the first entry associating the power conversion efficiency with the first operating condition and the second operating condition.

18 . The computer-readable medium of claim 17 , wherein the first operating condition is an amount of power provided by the PSU.

19 . The computer-readable medium of claim 17 , wherein the second operating condition is a temperature at the PSU.

20 . The computer-readable medium of claim 17 , wherein the first time is determined based on a timer arranged to periodically indicate that a predetermined amount of time has elapsed or based on determining that a change in a value of the first operating condition exceeds a first threshold.
