Abstract: The present disclosure provides a system and method enabling a self-burn-in test for a power supply device (PSD) of a server system using a multi-phase scheme. The PSD comprises a power-width modulation (PWM) controller, and a plurality of power stages. Each of the plurality of power stages comprises a driver, a high-side MOSFET, and a low-side MOSFET. In one aspect of the present disclosure, upon receiving a test mode command from a controller of the server system, the PWM controller can send a PWM signal to switch a specific power stage to the On state, and send at least another PWM signal that switches other power stage(s) of the plurality of power stages to the Tri-state. During a subsequent self-burn-in test of the specific power stage, low-side MOSFET(s) of the other power stage(s) can function as a load for the specific power stage.

Abstract: Various embodiments of the present technology provide methods for boosting a voltage differential of an energy storage by using a boost component, determining a server system being switched to a boost mode, and discharging the energy storage to provide additional power supplies to the server system during the boost mode. In some embodiments, processing demands of a server system can be monitored. In response to determining that a boost mode is needed to support processing demands of the server system or detecting a component being a bottleneck in processing pipelines of the server system, a boost activation signal can be generated. The boost activation signal can cause a CPU, the bottleneck component, or another component of the server system to operate under a higher clock speed such that a higher processing capacity can be achieved.

Abstract: A system includes one or more data processors and a non-transitory computer-readable storage medium containing instructions which, when executed on the one or more data processors, cause the one or more data processors to perform operations. The operations include receiving a design schematic, extracting keywords from the design schematic, and sorting the design schematic by the extracted keywords. The operations further include extracting a part number of a component from the sorted design schematic, comparing the component associated with the part number with a reference component associated with the part number, and displaying a result of the comparison indicating whether the component and the reference component match.

Abstract: A test load circuit includes a test load, a current sensor, and comparator. The test load is connected to a voltage source of a power supply. The current sensor is configured to detect the amount of current flowing through the test load. The comparator has a first input connected to a feedback signal having a voltage associated with the test load current, a second input connected to a command signal having has a voltage associated with a target current through the test load, and an output connected to the test load. The output of the comparator has a voltage that is based on the current difference between the target current and the test load current. The test load has a variable resistance that is controllable by the output of the comparator to adjust the test load current and cause the test load current to match the target current.

Abstract: A power supply circuit includes a power converter, an input voltage source, and a clamping circuit. The power converter has an input pin, an output pin, and an enable pin. The input voltage source is electrically connected to the input pin, and provides an input voltage to the input pin. The clamping circuit is electrically connected to the enable pin of the power converter. When the input voltage increases to at least a threshold input voltage, the clamping circuit is configured to activate the power converter to provide an output voltage at the output pin. When the input voltage decreases below the threshold input voltage, the clamping circuit is configured to deactivate the power converter and prevent the power converter from being re-activated within a predefined time period.
