  • Publication number: 20230333527
    Abstract: An information handling system includes a power supply and a baseboard management controller. The power supply determines a first maximum output power level, determines that an environmental condition of the power supply has changed, determines a second maximum output power level different from the first maximum output power level based upon the changed environmental condition, and stores the second maximum output power level to a first register of the power supply. The baseboard management controller sets a power level demanded by a load of the information handling system to be within the first maximum output power level, reads the first register, and sets the power level demanded by the load to be within the second maximum output power level in response to reading the register.

  • Patent number: 11429171
    Abstract: A system for controlling voltage operation of a power supply unit (PSU) for an information handling system. If the PSU is established as a High-Line power supply and is a dual wattage unit, Low-Line capabilities are disabled and the PSU turns off if power drops below a High-Line minimum voltage. If the PSU is established as a Low-Line PSU or is not dual wattage unit, the PSU is maintained in a current operational state and is either reset or turned off before making changes.

  • Patent number: 11086390
    Abstract: An information handling system has power supply units (PSUs), each of which includes an input over current warning (OCW) setting that provides a reference for an amount of an input current drawn by a corresponding workload. Each of the PSUs sends an interrupt to a baseboard management controller (BMC) when the amount of the input current drawn by the corresponding workload exceeds the corresponding configured input OCW setting. In response to the received interrupt, the BMC requests an adjustment to the corresponding workload.

  • Patent number: 10095293
    Abstract: A system may implement a method for determining the operating capability of a power supply based on multiple environmental factors. Information about environmental factors may be obtained from sensors in the power supply or received from a management controller. These environmental factors may include temperature, line voltage, backpressure, or altitude. A power supply capability analyzer within the power supply may determine that, based on the environmental conditions, it is safe to increase the operating capability of the power supply, or that the operating capability of the power supply should be decreased. After determining the best operating capability for the power supply, it may be communicated to the management controller, after which it may affect the allocation of power in the system. Similar adjustments in operating capabilities may be made for all power supplies in a system or adjustments may be made to individual power supplies based on local environmental conditions.

  • Patent number: 9261942
    Abstract: A method, system, and information handling system provides better system power consumption of a redundant power system having a plurality of power supply units (PSUs) by taking into consideration each PSU's sleep power consumption during selection of one or more PSUs to place into a “hot spare” sleep mode. For each PSU, power efficiency data at different load ratings are measured and stored. During the PSU selection, a calculation of system power consumption is conducted on each of several configurations where a different PSU is hypothetically disabled. Each calculation takes into consideration both the sleep power consumption of a disabled PSU and power efficiency data of an enabled PSU. Selection of one or more PSUs to disable is determined according to the configuration yielding the lower or lowest system input power consumption based on the results of the calculations.
