Impact of dielectric deterioration on the conducted EMI emissions in the DC-DC boost converter
Piotr Musznicki1, Jean-Luc Schanen2, Pierre Granjon3, Jarosław Јuszcz1

The magnitude of emitted noise generated by DC-DC converters depends on their electrical behavior and parameters. Some of these can change during the converter life time, especially due to some deterioration process. In this paper the impact of the dielectric materials aging is presented using both circuit simulation and a digital signal processing method based on Wiener filtering. The change of the total EMI spectrum as a function of the dielectric property has been investigated. Application can be either aging diagnostig, or a forecast of the EMI spectrum evolution with the time.
