    Abstract

    The paper examines the possibility to exploit the inductance of wound aluminum foil capacitors in order to realize an integrated component. Objective is the design and construction of an integrated inductor/capacitor to filter harmonic modulations as an alternative to the conventional passive filter, consisting of capacitor and inductor as discrete components with the prospect of reducing size, material and consequently costs. The principle functioning of the integrated component resulting from the position the supply terminals are placed on the aluminum foils is being demonstrated. An analysis of technical and geometric parameters leads through a calculation scheme to the design of such an integrated component. Finally, the construction of a manual winding machine enables the wrinkle free winding of the four foils on a central core to produce a pilot model operational at 400 V with multiple access terminals providing hence diverse experimentation possibilities. Most significant result is the measured current frequency characteristic of the pilot model revealing clearly its series resonant behavior with a quality factor close to ten, well comparable to values of conventional industrial filters indicating thus at this stage reasonable prospects for such an integrated component to operate as a filter in the grid absorbing harmonic modulations.
