Patent number: 9829967Abstract: A power subsystem is configured to manage the maximum power usage of a computer subsystem. A power detector determines when power usage approaches the maximum capability of the power supply. The power detector generates a signal that corresponds to power usage. A controller then applies the signal to the system voltage regulator as a secondary regulation function such that the output voltage is reduced in a manner that supports maximum operating voltage while limiting power usage to within the capability of the power supply. The controller may configure the signal to implement the secondary regulation function as a modification of the feedback voltage, the reference voltage, or the current feedback of the regulator. As a result the subsystem causes the computer subsystem to operate at an optimum point on the voltage-current curve of the power supply.Type: GrantFiled: October 8, 2015Date of Patent: November 28, 2017Assignee: NVIDIA CorporationInventors: Sam Duell, Jonah Alben, Andrew R. Bell, Ming Chen, Gabriele Gorla, Qi Lin, Henry Pang, Gokul Santhirakumaran
