To reduce the diameter of a power conversion apparatus. The power conversion apparatus comprises power modules (2), a shielding plate (3), and a bus bar (6) electrically connected with the power modules (2), which are disposed to be layered in this order on one side of a heatsink (1). The plural power modules (2) are annularly disposed along a surface of the heatsink (1). Then, the power modules (2) disposed annularly, the shielding plate (3), and the bus bar (6) are disposed to overlap each other at least partially when viewed in a layering direction. |
