    Abstract: Examples, disclosed herein, energize a first power supply through an enablement of a first relay to provide power to a load while a second power supply remains de-energized through a disablement of a second relay. Additionally, the examples detect a fault associated with the first power supply and de-energize the first power supply through a disablement of the first relay. Further, the examples energize the second power supply through an enablement of the second relay to provide power to the load, in response to the disablement of the first relay.

    Abstract: Examples described herein relate to a system controller for tracking a characteristic system energy of a computing system. The system controller may retrieve the characteristic system energy of the computing system from a voltage regulator (VR). The VR may include a VR controller, one or more phase converters, and an output capacitor coupled to a load to provide an operating voltage to the load. The characteristic system energy is related to a sum of capacitances comprising a capacitance of the output capacitor and a capacitance of the load and is determined by the VR controller based on a voltage at the output capacitor and a charging current or a discharging current of the output capacitor via the one or more phase converters. Further, the system controller may determine whether to initiate a corrective action for the VR based on a comparison between the characteristic system energy and a threshold value.

    Abstract: An electronic fuse (e-fuse) for controlling input current of a load includes a transistor switch and a transorb device that is coupled in parallel to the transistor switch between a source and a drain of the transistor switch. A circuit comprising the transistor switch and the transorb device in parallel comprises a first end and a second end. The first end of the circuit is coupled to a power bus. The second end of the circuit is coupled to a first node of the load. The e-fuse includes an RC circuit comprising a resistor coupled in series with a first capacitor. The RC circuit is coupled between the power bus at the first end of the circuit and a return. The return is coupled to a second node of the load. The e-fuse includes a second capacitor that is coupled between the return and the second end of the circuit.

    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 supplemental power supply system of a computing device may determine an occurrence of a transient at a processor of the computing device having a first electrical power supplied by a primary power supply of the computing device different from the supplemental power supply system. A discharging circuitry of the supplemental power supply system may, in response to determining the occurrence of the transient: discharge electrical energy from energy storage of the supplemental power supply system and supply a second electrical power to the processor using the electrical energy discharged from the energy storage.

    Abstract: An example system includes a failure detection circuit. The failure detection circuit is to detect a failure of a first power source electrically coupled to a first load. The failure detection circuit is to output a first signal indicating the detection of the failure of the first power source. The system also includes a current regulating circuit. The current regulating circuit is electrically coupled to the failure detection circuit. The current regulating circuit is to electrically couple a second power source to the first load based on the first signal output by the failure detection circuit. The current regulating circuit is to restrict a first current from the second power source.

    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.
