ABSTRACT:
To provide an AC/DC converter including a resonant converter which reliably supplies a constant DC power supply voltage (U.sub.out) in a wide output power range, while using a minimal number of components, and in which the input impedance of the AC/DC converter should have a minimal reactive impedance, both a capacitive (C2) and an inductive (n3) coupling of the resonant converter (8) to a point (5) between the resonant converter (8) and a rectifier arrangement (1) is provided. The rectifier arrangement is used for rectifying an AC voltage (U.sub.in) applied to the AC/DC converter.
