Abstract
A power factor correction circuit () comprises an input for receiving an input voltage (U), an inductance () coupled to the input, a switching means () that is coupled to the inductance () and that is controllable in order to either charge or discharge the inductance (), and a control device (). The control device () is set up in order to produce a control signal (Ctrl) for controlling the switching means () on the basis of a parameter value. The control device () is set up in order to ascertain the parameter value on the basis of an arithmetic sign of a time derivation for the input voltage (U).
