The filter (16) has network terminals (2) for connection with an electrical supply network. Device terminals (4) are provided for connection with an inverter, a boost converter (9) and a pulse-controlled inverter (12) producing harmonic current. A shunt arm extends parallel to the terminals, and includes a damping resistor (R15) series to a capacitor (C13) in a shunt arm section, where filter frequency is associated to the shunt arm. A bridging arm bridges the shunt arm section. The bridging arm includes low impedance than the shunt arm section for a frequency above the filter frequency. |
