Abstract
Exemplary systems, apparatus, and methods relate to a current limiting device on each of two or more load branches that limits the current drawn by each load branch to a branch current allocation for that branch, where each of the current limiting devices is configured to automatically communicate messages to negotiate adjustments to the branch current allocations among each of the load branches while maintaining the sum of the branch allocations substantially at or below an available capacity of the supply branch. In an exemplary embodiment, a system of intelligent power modules (IPMs) may operate together to automatically negotiate capacity sharing among a number of load branches by adapting to the dynamic load conditions in order to takes improved advantage of infrastructure power handling capability without exceeding a predetermined capacity of the supply branch.
