Abstract
A method of controlling two or more sources of electrical power to supply electrical power to a shared bus. Each source of electrical power has a rated power P, a maximum overload power P, and is operable along a multi-voltage droop slope, the multi-voltage droop slope including a share region and a catch region, the share region being defined by an upper voltage limit, Vand a base voltage V, and the catch region being defined by the base voltage Vand a lower voltage limit V.
