Power Module (PM) core-specific parameters for a detailed design-oriented inductor model

Abstract

This paper obtains shape-related parameters and functions of a Power Module ferrite core for a design-oriented inductor model, which is a fundamental tool to design any electronic power converter and its control policy. To improve accuracy, 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.
