| 摘要 |
The invention relates to an AC/DC converter comprising a resonance converter (A3), which is suitable, for example, for operation with different AC mains voltages from different AC power grids. The invention makes use of, inter alia, the following ideas: use of a bridge circuit (A4) which can be driven both as a full-bridge circuit and as a half-bridge circuit; use of an arrangement (A2) working as an up-converter coupled at least via a capacitor (C2) to the resonance converter (A3); use of a transformer (T) in the resonance converter (A3) and realizing the point (7) at which the arrangement (A2) working as an up-converter is capacitively (C2) coupled to the resonance converter (A3) in that the primary winding of the transformer (T) is divided and this dividing point is arranged as said point (7).
