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.
Claims20
A method comprising:
- providing a first power supply unit (PSU) and a second PSU, each PSU associated with a corresponding power conversion efficiency profile;
- determining a first operating condition at the first PSU at a first time;
- determining a second operating condition at the first PSU at the first time;
- determining a power conversion efficiency of the first PSU corresponding to the first time;
- generating a three-dimensional power conversion efficiency profile,
- the three-dimensional power conversion efficiency profile electronically associating the power conversion efficiency with the first operating condition and with the second operating condition;
- and
- engaging an operation of the second PSU based on the three-dimensional power conversion efficiency profile.
A system comprising:
- a data processing device;
- a first power supply unit (PSU) and a second PSU to provide power to the data processing device, the first PSU and the second PSU associated with a corresponding power conversion efficiency profile;
- a power management unit coupled to each of the first PSUs and the second PSU, the power management unit to:
- determine a first operating condition at the first PSU at a first time;
- determine a second operating condition at the first PSU at the first time;
- determine a power conversion efficiency of the first PSU corresponding to the first time;
- generate a three-dimensional power conversion efficiency profile, the three-dimensional power conversion efficiency profile electronically associating the power conversion efficiency with the first operating condition and with the second operating condition;
- and
- engage operation of the second PSU based on the three-dimensional power conversion efficiency profile.
A non-transitory 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 first power supply unit (PSU) at a first time;
- determine a second operating condition at the first PSU at the first time;
- determine a power conversion efficiency of the first PSU corresponding to the first time;
- generate a three-dimensional power conversion efficiency profile corresponding to the first PSU, the three-dimensional power conversion efficiency profile electronically associating the power conversion efficiency with the first operating condition and the second operating condition;
- and
- engage an operation of the second PSU based on the three-dimensional power conversion efficiency profile.
