摘要： 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.

摘要： For reducing the amount of circuitry and losses in double highpasses for filter arrangements in networks with a high voltage level, the two resonance frequencies and Q-factors of the double highpass are tuned so that in a critical harmonic range, at most a harmless slight resonance peak can occur, for which purpose a series capacitor together with a series choke are connected in series with a shunt circuit grounded, in the case of high voltage and ungrounded in the case of medium voltage, of ohmic, inductive and capacitive circuit elements connected to the network.
