Flux converter with power factor correction

A method for operating a flux converter for converting an input-side AC voltage into an output-side DC voltage to provide a power factor correction comprising a transformer having a plurality of serially arranged primary windings, a secondary winding wound in a same direction as the plurality of serially arranged primary windings, a storage capacitor in series with a first primary winding of the plurality of serially arranged primary windings, a first switch for switching the storage capacitor to the input-side AC voltage in a clocked manner by rectification elements and a second switch for switching a second primary winding of the plurality of serially arranged primary windings to the storage capacitor in a clocked manner, the method comprising:

• transferring, through a first primary winding of the at least two primary windings, electrical energy introduced on the input-side to a secondary side of the flux converter in a first conducting phase of a work cycle and storing the transferred energy in the storage capacitor;
• and
• transferring, through a second primary winding of the plurality of primary windings, electrical energy from the storage capacitor to the secondary side of the flux converter in a second conducting phase;
• wherein the storage capacitor is connected in a clocked manner to the input-side AC voltage by the rectification elements to the first switch and the second primary winding of the at least two primary windings is connected in the clocked manner to the storage capacitor by the second switch.
