Abstract: An inrush current limiting device and to a power factor correction circuit including an inrush current limiter. In particular, the application relates to a power factor correction circuit for controlling an inrush current limiter in a power conversion system used as a power supply. An inrush current limiting device for limiting inrushing current to a connectable load includes a first node and a second node, a resistive limiter unit for limiting current flowing through said limiter unit from said first to said second node, and a controllable bridging device which is connected between said first and said second nodes in parallel to the limiter unit, wherein the bridging device includes a semiconductor switch and a charge pump circuit connected to a control terminal of the semiconductor switch for controlling the semiconductor switch.
