Abstract

This paper obtains shape related parameters and functions of a Power Module ferrite core which can be required in a design-oriented inductor model, which is a fundamental tool to design any electronic power converter and its control policy. Some particular modifications have been introduced into the standardized method of obtaining characteristics core areas and lengths. Also, a novel approach is taken to obtain the air gap reluctance as a function of air gap length for that specific core shape.
