Abstract
The power conversion apparatus includes an inverter circuit which converts a DC current into an AC current and have a U-phase, V-phase, and w-phase power semiconductor modules, and a capacitor module for smoothing the DC current. Each of the power semiconductor modules is configured separately and connected to a first bus bar. The first bus bar is configured with a first positive side bus bar, a first negative side bus bar, and a first insulation member arranged between the first positive side bus bar and the first negative side bus bar. The first bus bar includes a first to third terminals to which the U-phase, V-phase, and W-phase power semiconductor modules are connected, respectively, and a fourth terminal connected to a terminal of the second bus bar protruding from a surface of sealing material of a second bus bar.
