2. Disturbance generation in static converters

The origin of electromagnetic disturbances created by a static converter device can be understood by means of circuit-type electrical modeling. This can then be used to simulate the structure's EMC behavior, quite easily in terms of conducted currents using circuit-type solvers (SPICE or similar) and, more roughly, in terms of radiated fields, which requires integrating the geometric aspects of the converter and the environment where the intensity of the radiated fields is to be determined. The objectives of modeling are twofold:

• Computer-aided design (CAD), with a priori, which integrates EMC constraints, so as to reduce the costly testing and certification stages;

• analysis of complex phenomena in structures with a view to improving their operation.
