Abstract
The power conversion device includes a first semiconductor module, a second semiconductor module, a third semiconductor module, and a capacitor module. As viewed in a z direction, the first center line of the first semiconductor module, the second center line of the second semiconductor module, and the third center line of the third semiconductor module intersect the capacitor body. The first angle formed by the first center line and the second center line and the second angle formed by the second center line and the third center line are equal to each other. The lengths of the first busbar, the second busbar and the third busbar are equal to each other.
