    Abstract: A computing device comprises a primary printed circuit board (PCB), one or more computing components mounted to the primary PCB, a baseboard management controller (BMC) mounted to the primary PCB, a power subsystem, and a logic device coupled to the primary PCB. The power subsystem comprises a power controller with a first logic pin, and the logic device is communicably connected to the first logic pin. The logic device is configured to program the power controller by placing the power controller in a programming mode and inputting programming information into the power controller via the first logic pin.

    Abstract: 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.

    Abstract: An example system includes a server including a power supply and a microcontroller. The power supply may store parameters for a plurality of different ranges of overcurrent and a plurality of corresponding different time periods. The power supply may also receive information from the electrical component corresponding to the speed at which the electrical component can reduce the amount of power the electrical component is consuming. The controller may receive information from the power supply to determine the amount of current that will cause an overcurrent event in the electrical component. The controller may signal the electrical component to reduce the amount of power the electrical component is drawing from the power supply in response to the detected amount of current corresponding to the overcurrent event.

    CPC classification number: H02H3/093 ,  H02H3/066

    Abstract: 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.

    Abstract: 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.

    Abstract: A method for detecting thermal events in an electrical system includes: synchronizing, via a controller, measurements of power consumed by each of a plurality of load elements during an interval with one another and with measurements of power supplied by each of a plurality of power sources to the plurality of load elements during the interval; determining a differential between a sum of the power consumed by the load elements during the interval and a sum of the power supplied by the power sources to the plurality of load elements during the interval; comparing the differential to a predetermined threshold; and determining whether a thermal event has occurred based on the comparison of the differential to the predetermined threshold.
