US Patent:

20210109582, Apr 15, 2021

Filed:

Oct 10, 2019

Appl. No.:

16/598531

Inventors:

- Round Rock TX, US
John Erven Jenne - Austin TX, US
Wayne Kenneth Cook - Round Rock TX, US
Wade Andrew Butcher - Cedar Park TX, US

International Classification:

G06F 1/28
G06F 1/30
G06F 1/3234
G06F 1/3296

Abstract:

An information handling system includes a power supply and a baseboard management controller (BMC). The power supply includes an input power monitor module and a communication interface. The input power monitor module is configured to detect a total harmonic distortion (THD) on a power input to the power supply, to determine that the THD is greater than a THD threshold, and to provide an indication that the THD is greater than the THD threshold on the communication interface. The BMC is coupled to the communication interface, and is configured to receive the first indication and to enter an item into a log of the information handling system in response to receiving the indication.

International Classification:

G06F 1/26
G06F 1/28

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.

WAYNE K. COOK - ROUND ROCK TX, US

International Classification:

H05K 7/20
H05K 7/14

Abstract:

An information handling system (IHS) automatically responds to a change in cooling medium that cools functional components. A cooling medium sensor senses a material characteristic of the cooling medium. A thermal management controller determines whether the material characteristic received from the cooling medium sensor is in one of a first range that is associated with the air cooling medium and a second range that is associated with the liquid cooling medium. In response to determining that the material characteristic is within the second range, the thermal management controller disables a thermal mitigation component that reduces a temperature of the functional components of the IHS.

International Classification:

H02M 3/156
H02M 1/42

Abstract:

In accordance with embodiments of the present disclosure, a power supply unit may include one or more stages including an output stage configured to generate a direct-current output voltage at an output of the power supply, an OR-ing metal-oxide-semiconductor field effect transistor (MOSFET) coupled between the output stage and the output, and a controller. The controller may be configured to measure a signal indicative of a voltage associated with the OR-ing MOSFET and determine an estimated output current of the power supply based on the signal.

International Classification:

US Classification:

713320

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.
