PROBLEM TO BE SOLVED: To provide an electric power conversion system which secures the strength of a case while preventing enlargement.SOLUTION: An electric power conversion system 1 includes: a semiconductor lamination unit 10 formed by laminating semiconductor modules 2 and cooling pipes 31 for cooling the semiconductor modules 2; a case 4 housing the semiconductor lamination unit 10; and a fixed component 100 housed in the case 4 and fixed to the case 4. The case 4 includes: a partition wall 5 facing the semiconductor lamination unit 10 in a lamination direction X; and a rib 6 which is formed so as to extend from the partition wall 5 to the opposite side of the semiconductor lamination unit 10. The rib 6 includes a component fixing part 7 which fixes the fixed component 100.SELECTED DRAWING: Figure 1 |
