  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.
