Abstract
An inverter includes at least one phase and two driver boards situated opposite each other, and at least one half-bridge, arranged between the driver boards and contacted electrically and/or by signals, with, in each case, a semiconductor package formed as a high-side switch and a semiconductor package arranged parallel thereto and formed as a low-side switch. A heat sink in the region of the half-bridges and connected to a cooling attachment under each semiconductor package, wherein the heat sink has a split design so that a first cooling branch is arranged in the high-side branch and a second cooling branch is arranged in the low-side branch, wherein the cooling branches are arranged at a distance from each other, and the cooling branches are fluidically interconnected in parallel or in series in a region outside the arrangement of the semiconductor packages.
