  • Publication number: 20210072809
    Abstract: A power converter device health check system includes a circuit that connects a power input to a power output, and that includes a first transistor directly coupled to ground and a capacitor in parallel with the first transistor. A controller device is coupled to the circuit and, during boot operations, prevents first power from being provided to the first transistor via the power input, and turns off the first transistor. While preventing the first power from being provided to the first transistor and with the first transistor turned off, the controller device provides second power to a circuit location in the circuit between the first transistor and the capacitor, and then determines whether a charge of the capacitor is below a threshold charge level. If the capacitor is below the threshold charge level, the controller device transmits a power converter warning message.

  • Publication number: 20210064490
    Abstract: A power consumption/power backup-based ride-through system includes a power supply system that is configured to supply power to the one or more components. A power backup device is coupled to the one or more components and the power supply system, and operates to monitor an amount of power provided by the power supply system to the one or more components. Based on the amount of power provided by the power supply system to the one or more components, as well as characteristics of the power backup device in some embodiments, the power backup device determines a ride-through time period for which the power backup device is capable of powering the one or more components. When the power backup device detects a loss of power to the one or more components, it powers the one or more components for the ride-through time period.

  • Patent number: 10936042
    Abstract: Embodiments of the present disclosure provide a method, an apparatus, an additional power supply, and a mainboard system for supplying power to a processor. The method comprises determining whether an additional power supply is able to provide extra power required by a processor in response to receiving a first signal from a power supply unit that supplies power to the processor. The first signal indicates that the power required by the processor exceeds maximum power that can be provided by the power supply unit. The method further comprises supplying power to the processor by at least the additional power supply in response to determining that the additional power supply is able to provide extra power. The embodiments of the present disclosure can supply the required extra power to the processor from the additional power supply so as to optimize the performance of the processor in an acceleration mode.
