The design of electrical filters for the suppression of electromagnetic interferences is a complex multiconstrained problem. The solution to such a problem aims to identify the suitable electrical circuit and components taking in consideration the nonidealities of the hardware as well as the parasitic phenomena. A customized optimization strategy is proposed for the automatic design of a ready-to-build filter solution. The design procedure integrates a circuital simulator and a library of electrical models to simulate the behavior of commercially available passive components. The obtained filter is designed to fit the end-user requirements (such as the common mode and the differential mode insertion losses) and the filter layout is automatically identified for simple prototyping on a printed circuit board. A selected set of filters have been simulated and developed to numerically and experimentally assess the effectiveness and show the flexibility of the proposed methodology.
