US 2018/0120910 A1 · SYSTEM AND METHOD TO MANAGE POWER FOR PORT CONTROLLER BASED POWER SUPPLIES USING A COMMON POWER SOURCE

Abstract

A system that delivers power between a common power source having a total deliverable system power and device loads. The system includes a power share interface that sums power consumed or requested by loads and determines availability of additional power. The system includes at least one peer power share interface with each peer interface associated with a port controller and communicable coupled to the power share interface over the system bus. The peer power share interface determines status of total power consumed or requested relative to total deliverable system power. The power share interface can in response to receiving the power level request cause the system to change power allocations to satisfy the power level requests.

Dependent claims

A system for delivering power between a common power source having a total deliverable system power and device loads connected to the ports of power supplies derived from the common power source, the system comprising:

a power sharing signal interface bus among two or more controllers for the ports of power supplies that determines power allowed by respective device loads;
and
wherein any one the controllers receives a power level request from a device load and uses the power share signal interface to determine availability of excess system power reserves to support the request.

Dependencies are inferred from the claim text.
