An object of the present invention is to reduce the size of a power conversion apparatus and to improve the reliability. The power conversion apparatus includes a power semiconductor module, a driver circuit board mounted with a driver circuit, an AC-side relay conductor for transferring the alternating current, and an AC connector. The power semiconductor module includes an AC-side terminal connected to the AC-side relay conductor, and a control-side terminal connected to the driver circuit board. The AC connector is provided on the opposite side of the power semiconductor module through the driver circuit board. The driver circuit board includes a transformer for transforming voltage from low to high and supplying the transformed voltage to the driver circuit, and a line for connecting the transformer and the driver circuit. Further, the driver circuit board forms a through hold provided on the side opposite to the transformer with the driver circuit interposed therebetween. The AC-side relay conductor is connected to the AC-side connector, through the through hole.
