Method of generating novel air gap layouts for laminated magnetic core miniature thin film inductors and transformers with a continuous function

Abstract

The present invention comprises a specially designed means of air gap optimization for magnetically permeable material used in electrical components, for example, inductors and transformers. First, an ideal inductance over current curve is selected, and a core start point, endpoint, start angle, and end angle are selected within the core or along the core edges. Given the ideal curve and the starting conditions, an air gap is designed which meets or comes as close as possible to the ideal curve selected. Multiple air gaps can be designed in a single core. The inclusion of novel partial air gaps enables curves to be reached that optimize the core for high and low currents.
