摘要：
A power factor correction circuit (11) comprises an input for receiving an input voltage (UIN), an inductance (21) coupled to the input, a switching means (24) that is coupled to the inductance (21) and that is controllable in order to either charge or discharge the inductance (21), and a control device (14). The control device (14) is set up in order to produce a control signal (Ctrl) for controlling the switching means (24) on the basis of a parameter value. The control device (14) 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 (UIN).
