Abstract

Official abstract text for this publication.

A semiconductor module structure includes: a semiconductor element portion including a plurality of capacitor elements; two bus bars sandwiching the semiconductor element portion and being electrically connected to the semiconductor element portion; and cooling fins, which are conductive, formed on respective surfaces of the bus bars at positions sandwiching the semiconductor element portion. Further, insulating refrigerant is provided in the cooling fins.

First claim

Opening claim text (preview).

What is claimed is: 1. A semiconductor module structure comprising: a semiconductor element portion including a plurality of capacitor elements; two bus bars separate from each other, the two bus bars sandwiching the semiconductor element portion and being electrically connected to the semiconductor element portion; and a plurality of cooling fins, each of which is conductive, wherein at least one of the plurality of cooling fins is formed on a surface of one of the two bus bars and extends from the surface and in a direction opposite from an other of the two bus bars, and at least one other of the plurality of cooling fins is formed on a surface of the other of the two bus bars, wherein insulating refrigerant is provided in the cooling fins, and wherein the bus bars are formed of an annular member, and a plurality of pairs of the semiconductor element portion and the capacitor elements are arranged along a circumferential direction of the bus bars. 2. The semiconductor module structure according to claim 1 , wherein the semiconductor element portion has a package structure housing semiconductor elements therein, and a space in the package structure is filled with a resin mold.
