Abstract

The present invention relates to an inrush current limiter device (4) for limiting inrushing current to a connectable load (3) comprising: at least one switchable IGBT-based limiter unit (5) for selectively limiting the inrushing current, having at least one current limiting conductor element for a limited leading of current and at least an IGBT-based switch (Q2), whereby the IGBT-based switch (Q2) is used as well as a controlled current limiter and as a by-pass element, and at least one control device (7) for controlling the IGBT-based switch (Q2), whereby the control device (7) comprises at least one IGBT-based switch supply (6) and means for realizing (8) a smooth flank of an output signal at the selected conductor element.
