PROBLEM TO BE SOLVED: To improve cooling performance of a capacitor without causing problems of increasing the number of components and complexity of assembly work.SOLUTION: An electric power conversion system 1 stores a circuit board 2B mounted with a capacitor 4 inside a storage case 10. The storage case 10 includes a main cover part 12a disposed to oppose to a capacitor mounting surface 2Ba of a circuit board 2B; a capacitor storage part 12b formed in such a mode as to be disposed, at a portion meeting the capacitor 4, projecting to the outside from the main cover part 12a and storing the capacitor 4 therein. The main cover part 12a is integrated with the capacitor storage part 12b.SELECTED DRAWING: Figure 4 |
