Evaluation of shunt and series power conditioning strategies for feeding sensitive loads

Proliferation of electronic equipment in commercial and industrial processes has resulted in increasingly sensitive electrical loads to be fed from power distribution systems. In this paper, series and shunt compensation schemes for feeding sensitive load centers are studied. The purpose of the system-level study is to reveal insights about these two mitigation strategies so that designers may select an appropriate compensation strategy for a given application. The paper presents analytical models for comparing series and shunt power conditioning approaches on the basis of power converter rating. Operating strategies, computer simulations and experimental verification of a series power conditioning approach are presented.
