Abstract

A circuit that has one or more control units that divide a load into two or more load groups, with each load group comprised of at least one load element. The one or more control units directing power from a power source to one or more of the load groups based on voltage variations in an output of the power source, load grouping, and operational parameters of the load elements. The circuit further includes one or more pass stages that regulate current flow from the power source to the load groups.
