The alternating current (AC) direct current (DC) intermediate circuit-converter has an AC input voltage range with zero voltage switching (ZVS) three-level DC to DC resonance converters. The outer primary circuits (S1,S4) and two inner primary circuits (S2,S3) are provided in the (ZVS) three-level DC to DC resonance converters. The primary circuits are arranged in series between two DC-intermediate circuit connections (3,4). A common connecting point (A) is connected between both the inner primary circuits by a low level controller-series resonant circuit with a resonance inductance. |
