Energy converters use power components whose commutation generates conducted or radiated electromagnetic perturbations. Whether they spread through conductors or by hertzian way, they can lead to malfunctions or breakdowns in the equipment used, which are more or less close to the perturbing source. Traditionally, filters and shielding limited the pollution level to the values imposed by the standards. Yet modifying the devices implies bulkiness and higher cost. Thus we have aimed at reducing and if possible removing filter and power converters. Regarding the conducted ElectroMagnetic Compatibility (EMC), the filters inserted on power converters can be suppressed by controlling the commutation of the switches. For that, it is compulsory to detect perturbing instants contained in a temporal waveform: To achieve this, we have made a theoretical study and correlated the results obtained with experimental measurements. This paper presents a measurement setup allowing this detection.
