Abstract:
A filter arrangement for damping line-conducted low- and high-frequency system perturbations, the filter arrangement being disposed between a system output and a converter side including an input load, the filter arrangement comprising:a symmetrical filter part including at least one first capacitor, each of the at least one first capacitor being associated with a respective system phase, the at least one first capacitor reducing an amplitude of an interference voltage, the symmetrical filter part further including a first parallel circuit coupled downstream from the at least one first capacitor, the first parallel circuit including a first damping resistor damping a resonance frequency and a first inductor providing system-frequency recharging currents; andan asymmetrical filter part including second capacitors in a first star connection downstream from the symmetrical filter part, a first star point of the first star connection coupled to ground via a second parallel circuit, the second parallel circuit including a third capacitor and a second damping resistor.
