Abstract
A power converter may be provided with: a stacking unit including semiconductor modules interposed between adjacent coolers; a capacitor disposed next to the stacking unit; a first bus bar; a second bus bar; and an insulating plate. The insulating plate is interposed between the first bus bar and the second bus bar, and includes cylinder portions. Each of the cylinder portions passes through corresponding one of third holes of the second bus bar, and allows corresponding one of branch portions of the first bus bar and corresponding one of terminals of the semiconductor modules to pass therethrough. An emitting angle of laser beam that bonds each of the terminals and the corresponding one of the branch portions is adjusted such that reflected beam of laser reaches the corresponding one of the cylinder portions. The cylinder portions are colored in a color comprising a wavelength of the laser.
