Adaptive filter with Y capacitors for a 3-phase DC on-board electrical system

A power converter for an on-board electrical system of an electrically driveable vehicle, having a first line for a first potential, a second line for a second potential, a third line for a reference potential and a filter device that has

• a first terminal that is connected to the first line,
• a second terminal that is connected to the second line,
• a third terminal that is connected to the third line,
• a first capacitor via which a first current path is routed from the first terminal to the third terminal,
• a second capacitor via which a second current path is routed from the second terminal to the third terminal, and
• a switching device that is configured to switch between a first filter mode and a second filter mode on the basis of control information,
• wherein
• the filter device further has a third capacitor that forms an electrically conductive connection between a center node, which is between the first capacitor and the second capacitor, and the third terminal, wherein the first current path and the second current path are routed past the third capacitor to the third terminal in the first filter mode and are routed via the third capacitor to the third terminal in the second filter mode.
