Abstract (en)
[origin: WO2012028475A1] The invention relates to a device (1) for suppressing high-frequency currents (IZ) in infeed lines to an inverter having a common-mode impedance (2), comprising a magnetic core (3) set up for inductively coupling the infeed lines, wherein the current load on the common-mode impedance is minimized, wherein a snubber impedance unit (4) is inductively coupled to the common-mode impedance (2) and has a frequency-dependent impedance.
