Abstract
For the purpose of power factor correction, an inductance () is supplied with an input voltage (Vin), wherein a controllable switching means () that is coupled to the inductance () is actuated in order to selectively charge and discharge the inductance (). A control device () for actuating the switching means () is designed such that it actuates the switching means () selectively on the basis of one of a plurality of modes of operation. In a first mode of operation, a switch-on time is stipulated for the switching means () on the basis of a minimum waiting time and on the basis of a voltage that drops across the switching means ().
