Abstract
A power factor correction device for an AC voltage supply system includes a transformer which is interconnected, on the secondary side, to form a star point circuit and which has a secondary-side connection for each phase. A module series circuit with at least two switching modules, which are connected in series and each of which has at least four switches and a capacitor, is respectively connected between each of the secondary-side connections of the transformer and the star point of the star circuit. There is provided a transformer which is a high-leakage-reactance transformer.
