Abstract
A power module includes a power unit. The power unit includes a power semiconductor and a substrate. In order to improve the reliability of the power module, the substrate of the power unit is directly connected in an integrally bonded manner to a surface of a heat sink. The power unit is surrounded at least partially by a housing. The housing includes a housing frame which is connected liquid-tight to the surface of the heat sink and formed from a first dielectric material, and a housing cover which is connected to the housing frame to close the housing and is formed from a second dielectric material.
