Patent number: 11652346Abstract: A system and method of protecting the input components of a power supply. An input overcurrent protection module is provided, which may be implemented in firmware, which monitors the input current through an input interface of the power supply. When the input current exceeds a threshold current (i.e., a current above the maximum rating of an input component, such as an input cable), the input current protection module determines whether an input overcurrent event is occurring. When it is determined that an input overcurrent event has occurred, the input current protection module disables the output circuitry of the power supply and triggers a few timers. The input overcurrent protection module continues to monitor the input and, if the input current continues to exceed the threshold current, is configured to shut down the power supply. In this way, input components may be protected from overcurrent issues in high-power systems.Type: GrantFiled: March 24, 2022Date of Patent: May 16, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Rama Prasad Atluri, Stewart Gavin Goodson, II, Mark A Lawrence

Patent number: 11532981Abstract: A power supply system includes a plurality of power supplies coupled to a common power bus. Each of the plurality of power supplies adjusts an output voltage set-point within a droop window in response to an excursion sensed voltage on the common power bus reflecting the current load on the power supply system. In response to a transient in the sensed voltage being above or below the droop window, each power supply may shift its droop window up or down. If the droop window of each power supply is at a maximum or minimum value within a voltage regulation window, each power supply may respond to a transient in the sensed voltage by compressing the droop window.Type: GrantFiled: May 21, 2021Date of Patent: December 20, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Stewart Gavin Goodson, II, Daniel Humphrey, Robin Kel Schrader

Publication number: 20220198073Abstract: A method, system, and device for using an interface controller to validate and authenticate controller code for a commodity device to be included within a computer system (e.g., a power supply) are provided. In one example, a commodity device controller includes dynamic memory for control software (e.g., control code to control operation of the commodity device) that may be validated (and/or updated) using an interface controller. The interface controller may perform this update/validation at startup (or run-time) to ensure secure control over aspects of the computer device including the commodity device control code. If a security risk is detected it may be mitigated in various ways, including disabling of the commodity device. Control code provided by third-parties (e,g., supplier of commodity device) may be validated and secured using disclosed techniques.Type: ApplicationFiled: July 29, 2019Publication date: June 23, 2022Inventors: Stewart Gavin Goodson, II, Daniel Humphrey, Robin Kelley Schrader

Patent number: 11314867Abstract: In some examples, a trust controller generates a first value and send the first value to a target controller of a subsystem, and generates a first verification value based on the first value and a known good code image for the target controller. The trust controller receives a second verification value from the target controller, the second verification value based on the first value and a code image to be executed at the target controller. The trust controller determines whether the code image to be executed at the target controller is compromised based on the first verification value and the second verification value.Type: GrantFiled: March 26, 2020Date of Patent: April 26, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Stewart Gavin Goodson, II, Daniel Humphrey, Robin Kel Schrader

Patent number: 11228202Abstract: A system including multiple power supplies is provided. Each of the power supplies is configured to provide a standby power to a management unit in the system through a standby output and a main power through a main output, when an input power signal has been received for the system. The system also includes a resistor configured to receive a standby signal from each of the power supplies to raise a signal voltage, wherein the standby signal is a pre-selected current. The system also includes a controller in each of the power supplies, the controller configured to raise the signal voltage to the specified value when the signal voltage is greater than a threshold, and to enable the standby power from a respective power supply to reach the management unit when the signal voltage is within the specified value. A method to use the above system for a synchronized power supply to a management unit is also provided.Type: GrantFiled: February 6, 2019Date of Patent: January 18, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: David P.
