FIELD: electricity.
SUBSTANCE: semiconductor electric energy converter module contains power semiconductor modules (2, 4) which are connected mechanically to liquid heat sink (6) and by means of busbars (8) having busducts (26, 28; 28, 30) isolated from each other by insulating layer (32) are connected electrically to contacts (10, 12, 14) of semiconductor electric energy converter - insulating layer (32) has two isolating layers (36, 38), which are interconnected by material so that between these two isolating layers (36, 38) there is hollow space (40) of set shape which ends at input and output side at least at one lateral surface (48, 50) of this insulating layer (32); this hollow space (40) at input and output side is equipped with respective branch tubes (42), which are connected so that liquid can pass through liquid heat sink (6).
EFFECT: fabricating semiconductor electric energy converter module with cooled busbars of power semiconductor modules which electrical load cab me bigger than load of a standard semiconductor electric energy converter; at that permitted temperature for insulating layer and laminating material for busbars could be hold.
