Abstract

A parallel filter arrangement with at least two filters supplying current in line side sensing configuration and a number of sensors for measuring current. The sensors are used to determine the amount of current being supplied by the filters and the amount of current being supplied by a source. The filters adjust their supplied current in order to reduce or eliminate the amount of reactive or harmonic current being supplied by a source.
