POWER EXCURSION TOLERANT POWER SYSTEM

摘要

A power excursion tolerant power system includes at least one powered component. A system capacitance and at least one power supply are coupled to the at least one powered component. The at least one power supply is operable as a voltage controlled current source to supply power to the at least one powered component when a system load is below a predetermined threshold. The at least one power supply is operable as a constant current source, and together with the system capacitance, to supply power to the at least one powered component when the system load is above the predetermined threshold. A load reduction mechanism is coupled to the at least one powered component and operable to perform at least one load reduction action when the system load is above the predetermined threshold.

1. A power system, comprising:
at least one powered component coupling that is configured to couple to at least one powered component; and at least one power supply that is coupled to the powered component coupling and that is configured to:
operate as a voltage controlled current source to supply power through the at least one powered component coupling when a signal that is indicative of a system load indicates that the system load is below a predetermined threshold:transition, in direct response to the signal that is indicative of the system load indicating a system load increase above the predetermined threshold, from operation as the voltage controlled current source to operation as a constant current source; andoperate as the constant current source to supply power through the at least one powered component coupling when the signal that is indicative of the system load indicates that the system load is above the predetermined threshold.
