摘要
說(shuō)明書(shū)
The electric power conversion device 5 has N bus bars 282 constituting the above-described N line 13 and VH bus bars 284 constituting the above-described VH line 12H. These bus bars 282 and 284 are each formed by processing, for example, pressing a metal plate material having an excellent conductivity such as copper. The N bus bars 282 and the VH bus bars 284 are electrically connected to the power modules 110 and the smoothing capacitors C2. The N bus bar 282 and the VH bus bar 284 are provided on the outer peripheral side of the housing 703 to extend in the axial direction α. The N bus bar 282 and the VH bus bar 284 extend from the smoothing capacitor C2 toward the input terminal block 240 in the axial direction α, and are electrically connected to the input terminal block 240.
