ABSTRACT:
In one form of the invention, a method for improving power factor in a multiple phase power distribution system coupled to a load is disclosed, comprising the steps of (a) sensing an actual voltage of each of the multiple phases, (b) sensing an actual current being sourced by each of the multiple phases, (c) calculating an ideal current value for each of the multiple phases such that each the ideal current is in phase with a respective one of the actual voltages, (d) coupling at least one energy storage device for sinking current from at least one of the multiple phases wherein the actual current is less than the ideal current and (e) coupling the energy storage device for sourcing current to at least one of the multiple phases wherein the actual current is greater than the ideal current. Other systems, devices and methods are disclosed.
