ABSTRACT:
A high-pass element of a filter assembly for a line connected to static converters having a high voltage level for filtering harmonics and damping resonance sites includes a first series circuit including a first capacitor, a first choke coil, and a second choke coil. A resistor is connected in parallel with the choke coils. A second series circuit is connected directly in parallel with the second choke coil. The second series circuit includes a second capacitor and a damping resistor. On the other hand, the second capacitor and the damping resistor may be in parallel with the second choke coil and at least one other series circuit may be connected in parallel with the second choke coil. The at least one other series circuit includes a series capacitor and a series resistor.
