| Zusammenfassung: | The invention relates to a device for effecting the basic interference suppression of a matrix converter (
2
) comprising an input filter (
10
) provided with capacitors (
14
). According to the invention, a suppression capacitor (CY
1,
CY
2,
CY
3
) is provided for each input phase (U, V, W) of the matrix converter (
2
). Said suppression capacitors are electrically connected in star, and the star point (
16
) thereof is connected in an electrically conductive manner to the ground potential. These suppression capacitors (CY
1,
CY
2,
CY
3
), which are electrically connected in star, are electrically connected in parallel to the capacitors (
14
) of the input filter (
10
). By using few capacitors and an input filter (
10
) of a matrix converter (
2
), a device is thus obtained for effecting the basic interference suppression of the matrix converter (
2
). This device can also be considered, analogous to a frequency converter, as a network filter. |
