“…Suppression of EMI noise in power electronic design has recently gained further relevance due to the continuous increase of power converters' switching frequencies, fostered in turn by the introduction of new wide bandgap electronic devices, which lead to very fast switching operation and thus to the increase of electromagnetic emissions [3,4]. Moreover, the increasingly pervasive use of power electronics in technical fields like transportation, where saving volume and weight is pivotal, has also raised the issue of converters' power density in recent years [5,6]. This aspect is particularly critical for passive discrete EMI filters (still widely used due to the simplicity of their practical setup) whose impact on total weight and volume of power converters is significant (up to 25-30%) [7].…”

Power density is one of the most significant issues in designing electromagnetic interference (EMI) filters for power electronic-based applications. Therefore, an effective EMI filter design should consider both its capability to ensure the compliance with the related EMI standard limits and the possibility to build it by suitable components leading to the most compact configuration as well. To fulfill the above requirements, in this paper, an automatic procedure to get an improved design of EMI filters is proposed. Specifically, according to the proposed method, the values of filter parameters for both common mode (CM) and differential mode (DM) sections are selected by a genetic algorithm (GA) exploiting the in-circuit insertion loss, thus obtaining a more effective design. Besides, the components that set up the filter are selected by a rule-based procedure searching through a suitable database of commercial components to identify those allowing for the maximum power density. Experimental tests were performed using an inverter-fed induction motor drive as a case study, and the obtained results have demonstrated the validity of the proposed approach.
