COMMON MODE FILTER WITH Y-CAPACITORS AND SEPARATING SWITCH FOR DECOUPLING SAME FROM THE REFERENCE POTENTIAL

A power converter for an onboard electrical system of a vehicle which can be electrically driven, has a first line for a first potential, a second line for a second potential which differs from the first potential, and a third line for a reference potential which lies between the first potential and the second potential. A filter device has a first capacitor and a second capacitor and is designed to establish a first electrically conductive connection between the first line and the third line via the first capacitor and an electrically conductive connection between the second line and the third line via the second capacitor on the basis of control information and sever the electrically conductive connections along at least one current direction.
