PROBLEM TO BE SOLVED: To provide an electric power conversion system capable of reducing the size, and surely cooling a capacitor.SOLUTION: An electric power conversion device comprises: a first electric conversion part 100 including a first cooling device 106 and a first power semiconductor module 101; a second electric power conversion part 400 including a second cooling device 406 and a second power semiconductor module 401; a capacitor 131 that is electrically connected to the first and second power semiconductor modules; wiring conductors 111 and 121 that connect the capacitor to the first and second power semiconductor modules; and a supporting member 171 that supports the first and second electric power conversion parts. The capacitor is positioned between the first and second electric power conversion parts and is positioned at a space surrounded by the first electric power conversion part, the second electric power conversion part, the wiring conductor, and the supporting member. The space forms a ventilation trunk.SELECTED DRAWING: Figure 1a
