Abstract

The present disclosure relates to semiconductors. Some embodiments may include a series circuit arrangement of power semiconductors comprising: cooling-water boxes arranged on the semiconductors and electrically connected to them; two cooling-water distributor lines; respective branchings on the cooling-water distributor lines for the cooling chambers; and a control electrode arranged on the cooling-water distributor lines. The cooling chambers are connected in parallel between the cooling-water distributor lines with respect to a cooling-water stream. The cooling chambers are connected to the branchings via a respective connecting line. For at least some of the cooling chambers, the branchings on the cooling-water distributor lines are arrayed relative to the position of the respective cooling chamber in offset manner in relation to a geometrically shortest possible link to the cooling-water distributor lines, so that a difference of potential between the cooling chambers and the branchings is minimized.
