PROBLEM TO BE SOLVED: To provide an electric power conversion system which is excellent in air-cooling performance.SOLUTION: An electric power conversion system 1 includes: a transformer 2 having a primary coil and a secondary coil; a first circuit part 3 connected with the primary coil side of the transformer 2; a second circuit part 4 connected with the secondary coil side of the transformer 2; and a housing 5 in which the transformer 2, the first circuit part 3, and the second circuit part 4 are disposed. In the housing 5, an air passage 6 which connects with the exterior of the housing 5 is formed in a vertical direction between a lower opening part 61 and an upper opening part 62. At least one of the transformer 2, the first circuit part 3, and the second circuit part 4 is disposed in the air passage 6. |
