The invention implements a filter circuit (100) for an electric drive (200), in which the filter circuit (100) comprises an x-type capacitor (CXi), a first y-type capacitor and a second y-type capacitor (CY1i, CY2i). An x-type capacitor (CXi) is coupled between the first filter output terminal pole and the third filter output terminal pole (212, 216) or between the first filter input terminal pole and the third filter input terminal pole (213, 217), and a first y-type capacitor (CY1i) is coupled between the third filter output terminal pole (216) or the third filter input terminal pole (217) and a reference potential or ground. A second y-type capacitor (CY2i) is coupled between the second filter output terminal pole (214) or the second filter input terminal pole (215) and a reference potential or ground.
