Systems And Methods For Providing Auxiliary Reserve Current For Powering Information Handling Sytems

摘要

Systems and methods are disclosed for providing auxiliary reserve current to power a system load of an information handing system using an auxiliary energy storage power source as an energy cache to selectably provide auxiliary reserve current to at least partially supplement the normal operating power supply (e.g., battery pack, AC adapter, AC/DC power source, etc.) of an information handling system during temporary times of increased current need by the system load of the information handling system.

主权项

1. An information handling system, comprising:
at least one multi-power mode processing device that is configured to operate in a first power mode having a first power consumption level and to temporarily operate in a separate second higher power mode having a second power consumption level, the second power consumption level being greater than the first power consumption level; voltage regulator (VR) circuitry having an input coupled to receive an input system power source and an output coupled to provide power to the multi-power mode processing device, the VR circuitry being configured to regulate current received from the input system power source to produce a base regulated current output that is sufficient to power the multi-power mode processing device at the first power consumption level but not at the second power consumption level; and a reserve current system comprising an auxiliary energy storage power source that includes one or more energy storage devices coupled to be selectably charged with stored energy taken from the input system power source, and the reserve current system being configured to selectably release the stored energy from the auxiliary energy storage power source as auxiliary reserve current sufficient to supplement the base regulated current of the VR circuitry output to power the multi-power mode processing device at the second power consumption level; where the reserve current system is configured to selectably provide a temporary pulse of the auxiliary reserve current to supplement the regulated base current provided to the multi-power mode processing device during the time when the multi-power mode processing device is operating in the second power mode.
