Abstract
Description
technical field
[0001] The invention relates to an inrush current limiter device for limiting inrush currents directed to a connectable load, comprising at least one switchable IGBT (Insulated Gate Bipolar Transistor) based limiter unit for selective Ground limiting inrush current, which has at least one current-limiting conductor element for limited conduction current, and at least one IGBT-based switch, wherein the IGBT (Insulated Gate Bipolar Transistor)-based switch (Q2) Used as a controlled current limiter and bypass element, and at least one control device for controlling an IGBT-based switch, wherein the control device includes at least one IGBT-based switching power supply and for implementing an output signal at a selected conductor element Device with smooth sides.
[0002] The invention further relates to a power factor control circuit connectable to and / or between a main fed and a load, comprising: an AC / DC converter with a capacitive buffer unit, and inrush curre...
