Claim of US Patent No. 9,907,215

1. A power electronic subassembly comprising:
a housing having an internally arranged cooling area, said cooling area being configured so that it can be cooled by a cooling
device integrated into said housing; and

a capacitor device arranged in said housing, said capacitor device having a capacitor with a first contact device of a first
polarity, a second contact device of a second polarity and a capacitor busbar system, said capacitor busbar system including
a first sheet-like shaped metal body and a second sheet-like shaped metal body;

wherein said first and second sheet-like shaped metal bodies are connected in an electrically conducting manner and are arranged
closely adjacent to one another over at least about 80% of their two-dimensional extent, and

wherein a first portion of said first shaped metal body has
a first subportion which is arranged parallel to and at a distance from said cooling area, and
a second subportion, which is in thermal contact with said cooling area, and which is connected to said first subportion by
an intermediate portion.
