EMI concerns in power electronic

The majority of EMI concerns are centered on radio frequency (RF) emission sources. Although most RF transmissions are achieved under controlled conditions, it is this transmitted energy that may create an interference which may affect the performance of many electronic devices. Conducted interferences may originate from the coupling of ambient radiated interference or may be capacitively or inductively induced in the cable by an emitting source. Our work is to develop new techniques to solve EMC problems in industrial power conversion systems. The power electronic functional aspects and the EMC noise aspects will be combined in an integral design approach. Our objectives are to use an approach in which functional, thermal and electromagnetic effects are taken into account. We will investigate new concepts and innovative techniques. In addition the methods used will be translated into useable design rules for industrial applications focused on EMI. This will enable industry to design power electronics faster and with lower risk. The first part of our work is focused on the modeling of motors and cables which have a large influence, from an EMI point of view, on the behavior of the main supply connected to it.
