PL Wpływ starzenia się dielektryków na poziom zaburzeń generowanych w impulsowym układzie podwyższającym napięcie
Języki publikacji EN
EN The magnitude of emitted noise generated by DC-DC converters depends of 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.
PL W artykule przedstawiono wpływ starzenia kondensatorów elektrolitycznych na poziom zaburzeń elektromagnetycznych generowanych przez układ podwyższający napięcie w oparciu o metody symulacyjne oraz cyfrowe przetwarzanie sygnału (filtracje Wienera). Wyniki przedstawiono w formie widm zaburzeń generowanych przez układ oraz transmitancji pomiędzy źródłem zaburzeń a zaburzeniami
