Abstract
A circuit arrangement for an onboard network of a motor vehicle, includes a line having a first inductivity and connecting a component of a power electronics of an onboard network with an element, wherein the component is adapted for being clocked during operation of the power electronics at a clock frequency; and an absorber circuit assigned to the line and having a second inductivity and a capacitance, wherein the second inductivity of the absorber circuit is coupled with the first inductivity of the line.
Claims19
A circuit arrangement for an onboard network of a motor vehicle, said circuit arrangement comprising:
- power electronics comprising a component which is clocked during operation of the power electronics at a clock frequency, the power electronics being connected, on the one hand, via a first line to a first element and, on the other hand, via a second line to a second element of the onboard network, with at least one of the first lines and the second lines having a first inductor configured as part of a ferrite core and surrounding the at least one line;
- and
- an absorber circuit comprising a second inductor, a resistor and a first capacitor connected in series, said second inductor of the absorber circuit being inductively coupled with the first inductor.
