Cooling arrangement for semiconductor converter device

In a multiphase converter circuit having two sets of converters, each including planar-type semiconductor controlled rectifier elements, connected in a bridge configuration, said converters being connected in parallel, with opposite polarities, to a load, and wherein anode reactor elements are connected between power supply lines for said circuit and said controlled rectifier element, an improved cooling arrangement for said converters wherein

• the rectifier elements disposed between each respective load terminal and associated anode reactor elements are aligned in sequence along an axis so that the adjacent electrodes of adjacent rectifier elements which belong to respectively different converters are of opposite polarities with respect to each other;
• and
• cooling elements are interposed between each pair of adjacent rectifier elements.
