Zusammenfassung:Operating device (A) for a luminous means, the operating device having at least one driver circuit for operating at least one luminous means (Last), an energy store (Cbulk) which supplies the driver circuit, a power factor correction circuit which is in the form of a boost converter, supplies the energy store (Cbulk) and has a storage inductor (Lb), an actively clocked switch (S) and a rectifier diode (D), wherein the storage inductor (Lb) has a secondary winding which is arranged in such a manner that said winding is magnetically coupled to the primary winding of the storage inductor (Lb) and is connected in series with a coupling capacitor.
