Abstract

For the purpose of power factor correction, an inductance (21) is supplied with an input voltage (Vin), wherein a controllable switching means (24) that is coupled to the inductance (21) is actuated in order to selectively charge and discharge the inductance (21). A control device (14) for actuating the switching means (24) is designed such that it actuates the switching means (24) 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 (24) on the basis of a minimum waiting time and on the basis of a voltage that drops across the switching means (24).
