PROBLEM TO BE SOLVED: To provide an electric power conversion system which can efficiently cool a connection electronic component.SOLUTION: An electric power conversion system 1 includes: a semiconductor lamination unit 2 formed by laminating a semiconductor module 21 and a cooler 22 which cools the semiconductor module 21; a connection electronic component (a capacitor element 4) which is electrically connected with the semiconductor module 21 through a bus bar 3; and a component case 5 which houses the connection electronic component. The semiconductor lamination unit 2 is disposed in a state where the cooler 22 is placed in contact with an outer surface 50 of the component case 5. A part of the bus bar 3 is disposed in the component case 5 and between the connection electronic component and the cooler 22. |
