SUPPLEMENTAL POWER SYSTEM FOR POWER EXCURSIONS
First Claim
1. A supplemental power system, comprising:
- at least one powered component;
a power system;
a first power supply path that is operable to supply power at a first voltage from the power system to the at least one powered component; and
a second power supply path that is operable to store power from the power system at a second voltage that is greater than the first voltage, wherein the second power supply path is further operable to supply the power stored at the second voltage to the at least one powered component during power excursions by the at least one powered component.

Abstract
A supplemental power system for IHS power excursions includes a processor and a memory coupled to the processor. A power system is coupled to the processor and a plurality of power supply paths. A first power supply path is operable to supply power at a first voltage from the power system to the processor. A second power supply path is operable to store power from the power system at a second voltage that is greater than the first voltage, and the second power supply path is further operable to supply the power stored at the second voltage to the processor during power excursions by the processor. In some embodiments, the second power supply path may include a boost converter to increase power at the first voltage to the second voltage, or may receive power output at the second voltage from a supplemental power rail in the power system.
