Beschreibung
Zusammenfassung:	This invention relates to an AC/DC converter to counter-relax current harmonic correction by connecting an input filter, a full-bridge rectifier, a boosting circuit and AC/DC converter and controlling IC in a way of electric coupling, among which, a transformer is set in the boosting circuit and the AC/DC converter, the transformer has a first, second and a third windings, the first and the second ones are in the primary side, the third is at the secondary side, the first belongs to part of the BOOST and the second and third belong to the converter, thus the power-factor correction function combines with the AC/DC circuit to form a single-stage power source converter to reduce usage of magnetic components.
