Optimized size design of integrated magnetic components using area product approach

Substantial reductions in size and costs of magnetic components and power supplies can be achieved by an integration of magnetic components on one core. So far, no adequate method is known for computerized design of integrated magnetics. In this contribution, an optimized size design approach of integrated magnetic components using area product formulation is presented. In a first step, optimal flux density and area product values are determined for discrete multiple-winding inductors and transformers. Using these results in a second step, optimal area products are calculated for integrated magnetic components, consisting of e.g. transformer and either resonant or filter inductor
