Abstract: No consideration is given to heat transferred from a semiconductor module to a capacitor via a bus bar module. The heat generated by a semiconductor module (1) is transferred to a bus bar module (3) via a DC terminal (1A) of the semiconductor module (1). As illustrated in FIG. 4(B), the heat transferred to the bus bar module 3 is then transferred to the pressing member 5 via the annular conductor 8 and the bolt 5A. Since the pressing member 5 is in close contact with the second cooler 2B, the heat transferred to the pressing member 5 is cooled by the second cooler 2B. On the other hand, the heat transferred to the convex portion 6A of the housing 6 is transferred to the first cooler 2A via the housing 6 and cooled. As a result, in the configuration in which a capacitor (4) is connected to the semiconductor module (1) via the bus bar module (3), the heat transferred from the semiconductor module (1) to the capacitor (4) can be suppressed.

In the case of attachment to a low voltage electrical device body, the state is returned to an initial state, the series connector is cut off, and the parallel connector pair becomes conductive.

Abstract: A sheet-shaped member 440 including a resin insulating layer 441 and a metal foil 442 is used. The sheet-shaped member 440 is deformed following warpage or step difference in a second conductor plate 431 and a fourth conductor plate 433, and therefore, the thickness of the resin insulating layer 441 can be set to a constant thickness of, for example, 120 ?m capable of securing insulation properties. By plastically deforming a metal-based heat conduction member 450 having a thickness of, for example, 120 ?m interposed between the sheet-shaped member 440 and a cooling member 340, the thickness of the metal-based heat conduction member 450 is changed to absorb the warpage or step difference generated in the second conductor plate 431 and the fourth conductor plate 433. This results in remarkable improvement in heat dissipation as compared with a case where the conductor plates are brought into contact with the cooling member 340 via an insulating layer alone.
