Abstract:
The side-by-side (primary-secondary) wound integrated magnetic component is often used to combine series inductance and transformer behaviour in LLC resonant converters and dual active bridge converters. This paper presents an easy to follow design procedure for this component, translating the component’s electrical specification into a physical design. A combination of reluctance modelling, the application of Ampere’s law and the introduction of an alignment factor, obtained through finite element analysis, is used to derive a model for the integrated magnetic component. The model is encapsulated within a design approach accounting for frequency, maximum operating flux density, etc., to ensure the final component is not oversized and meets the design specification.
