Abstract: The invention relates to a power converter comprising several semiconductors (1) and direct voltage and alternating voltage buses (8/9, 4) for electric contact between the direct and alternating voltage connections (3, 2) of the power semiconductors (1). The buses are divided into two parts so that the alternating voltage bus (4) and the direct voltage bus (8/9) do not come into physical contact with each other. One advantage of the invention is that no creepage paths between the direct voltage and alternating voltage buses need to be taken into consideration.
