查询词典 least squares approximation

The present invention relates to an inrush current limiter device for limiting inrushing current to a connectable load comprising: at least one switchable IGBT (Insulated Gate Bipolar Transistor)-based limiter unit for selectively limiting the inrushing current, having at least one current limiting conductor element for limited leading of current, and at least an IGBT-based switch, whereby the IGBT(Insulated Gate Bipolar Transistor)-based switch (Q2) 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, 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.
