In this paper, a complete computer aided procedure based on the power density concept\nand aimed at the automatic design of EMI filters for power electronic converters is presented. It is\nrule-based, and it uses suitable databases built-up by considering information on passive components\navailable from commercial datasheets. The power density constraint is taken into consideration by\nimposing the minimization of the filter volume and/or weight; nevertheless, the system in which\nthe automatically designed filter is included satisfies the electromagnetic compatibility standards\nlimits. Experimental validations of the proposed procedure are presented for two real case studies,\nfor which the performance and the size of the best filter design are compared with those related to a\nconventionally designed one.
