WebAn inductor is a current filtering device. By resisting change in current, the filter inductor essentially accumulates stored energy as an AC current crests each cycle, and releases that energy as it minimizes. Power inductors require the presence of an air gap within the core structure. The purpose of the gap is to store the energy, and to ...
