Dynamic power system adjustment to store energy for power excursions
First Claim
1. A power system, comprising:
- a power system connector that is configured to couple to a powered system and a system capacitance;
a power conversion device coupled to the power system connector and configured to provide a power system output to the system capacitance and the powered system; and
a power system output controller that is coupled to the power conversion device and configured to;
control the power conversion device to provide a first power system output level to the system capacitance and the powered system; and
determine that the performance of a workload by the powered system will exceed a power system output capability of the power system performing a workload and, in response, control the power conversion device to increase the first power system output level from the power conversion device to a second power system output level in order to increase the energy stored in the power system capacitance so that the increase in the energy stored in the system capacitance and the power system output capability of the power system provide sufficient power for the powered system to perform the workload.

Abstract
A power system is coupled to a powered system and a system capacitance. The power system includes a power system output sensor, a power conversion device, and a power system output controller. The power system output controller includes a powered system threshold that is related to a power excursion capability of the powered system. The power system output controller is operable, in response to receiving a power system output signal from the power system output sensor that exceeds the powered system threshold, to control the power conversion device to increase the power system output from the power conversion device in order to increase the energy stored in the system capacitance for use by the powered system during a power excursion. The powered system may include processors that draw power from the system capacitance during power excursions so as to not exceed the limits of the power system.
