Example Embodiment

[0040] The following will refer to Figure 1 to Figure 3 Embodiments of the present invention regarding power converters are described.

[0041] like figure 1 and figure 2 As shown, the power converter 1 has a semiconductor stack unit 10, auxiliary electronic components 2, a pressing member 5, and a housing 6 in which these components are housed.

[0042] The semiconductor stack unit 10 is formed by alternately stacking a plurality of semiconductor modules 11 and a plurality of cooling pipes 13 .

[0043] The auxiliary electronic component 2 forms a power conversion circuit together with the semiconductor module 11 .

[0044] The pressing member 5 presses the semiconductor stacked unit 10 along the stacking direction X of the semiconductor stacked unit 10 .

[0045] Each of the plurality of semiconductor modules 11 has a built-in semiconductor element therein.

[0046] The housing 6 has: a front wall 631 provided on the front side in the stacking direction X; a rear wall...

Abstract

An electric power converter has a semiconductor stacked unit, auxiliary electronic components, a pressing member, and a case for accommodating these components. The case has a front wall in a stacking direction, a rear wall, a pair of side walls, and inner walls. The inner walls include a partition wall that is disposed opposing the front wall, and a support wall that is formed so as to extend toward the rear wall from a rear end surface of the partition wall. A unit accommodation space for accommodating the semiconductor stacked unit and the pressing member is formed between the partition wall and the front wall. Auxiliary accommodation spaces for accommodating the auxiliary electronic components are formed between the partition wall and the rear wall.

Description

technical field [0001] The present invention relates to a power converter. Background technique [0002] Power converters are installed on vehicles such as hybrid and electric vehicles. [0003] The power converter is used to convert DC (direct current) power supplied from a battery provided in the vehicle into three-phase AC (alternating current) power for driving the drive motor. [0004] Such a power converter is disclosed in, for example, Japanese Patent Application Laid-Open Publication No. 2013-55840. [0005] The power converter disclosed in Gazette 840 is provided with a plurality of semiconductor modules, each having a built-in switching element, and a plurality of cooling pipes for cooling the plurality of semiconductor modules. [0006] A plurality of semiconductor modules and a plurality of cooling pipes are alternately stacked to form a semiconductor stack unit. [0007] The semiconductor stack unit is accommodated in the case together with the pressing membe...
