PROBLEM TO BE SOLVED: To minimize non-uniformity of a current flowing into the DC end of each power module in a power converter.SOLUTION: The invention is related to the power supply line bus bar in a power converter. A power supply line bus bar 91a is connected with the arm of a power converter, and the arm includes power modules 11-13 provided in order for the first direction and connected in parallel electrically. The power supply line bus bar 91a includes a main bus bar 50 having a connection 80, a center bus bar 65 connecting the connection 80 and the DC terminal 22P of a second power module 12, and a side bus bar 60 of a substantially line symmetrical shape which connects the connection 80 and the DC terminal 21P of a first power module, and connects the connection 80 and the DC terminal 23P of a third power module. |
