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