An apparatus for converting direct voltage of a first input side into direct voltage of a second output side has a first converter (1) located on the input side, a second converter (13) located on the output side and a transformer (9) arranged therebetween. A unit (14) is adapted to control semiconductor devices of turn-off type of the converters to vary the duty cycle of the voltage delivered on the alternating voltage side of the respective converter for controlling the appearance of the current through an inductance (12) associated with the transformer. |
