Abstract
The automotive power system is being increasingly expanded by adding high-dynamic power electronics. These components can potentially cause malfunction or failure of safety-relevant low-voltage components. The susceptibility to disturbances is often reduced by usage of oversized passive input electronics. This paper introduces an alternative means of disturbance suppression by the introduction of system integrated adaptive passive filters. A proposed methodology is presented for examining the suitability of potential access points within complex networks. An algorithmic procedure for the parametrization of several switchable bandpass filter stages is explained. The in-vehicle measurement demonstrates the effectiveness of the dimensioned filter being able to reduce disturbances at 70 kHz by more than 75 %.
