The invention relates to a converter comprising switching elements for chopping a direct voltage, in which turn-on phases of the switching elements alternate with one another, and comprising a circuit arrangement with resonant circuit elements processing the chopped direct voltage and serving for the supply of an output voltage. To improve such a converter in such a way that zero voltage switching (ZVS) can be ensured in an extended range of converter operations with possibly inexpensive converter modifications, it is proposed that the length of the dead-time phases, which are present between two consecutive turn-on phases and during which the switching elements are turned off, is automatically adapted so that switching losses, which occur particularly when the switching elements are turned on, can be minimized.
