    Abstract: An electronic device and a method for filtering common mode disturbances from a power electronic device are disclosed. In an embodiment the device includes a first capacitor coupled in series to a first one-way conductor, the first one-way conductor allowing current flow in one direction, wherein the first one-way conductor and the first capacitor are coupled between a load node and a reference potential and a second capacitor coupled in series to a second one-way conductor, the second one-way conductor allowing current flow in an opposite direction, wherein the second one-way conductor and the second capacitor are coupled between the load node and the reference potential. The device further includes a third capacitor being coupled between the load node and the reference potential, a first switch bypassing the first one-way conductor and a second switch bypassing the second one-way conductor.
