POWER CONVERTER MODULE WITH COOLED BUSBAR ARRANGEMENT Russian patent published in 2014 - IPC H05K7/20 

FIELD: electricity.

SUBSTANCE: invention relates to a power converter module with a at least one thermally active power semiconductor module (2, 4), mechanically connected to a liquid-cooled heat sink (6) and are electrically actively connected to leads of the power converter module by a busbar arrangement (8), having at least two power buses insulated from each other. The busbar arrangement (8) is connected via power and/or geometric closing with a second liquid-cooled heat sink (10). Between the top power bus of the busbar arrangement (8) and the second liquid-cooled heat sink there is a thermally active and electrically insulating layer (36). Additional power loss arising in the busbar arrangement (8) is removed through said second liquid-cooled heat sink (10), which is clamped to the surface of the busbar arrangement (8) of the power converter module using clamping elements.

EFFECT: designing a power converter module, the laminated set of buses of which allows efficient removal of heat using simple means.
