<P>PROBLEM TO BE SOLVED: To prevent generation of an inbalanced state in the current running through a plurality of semiconductor modules connected in parallel per each arm of a power converter. <P>SOLUTION: For DC intermediate electrolytic capacitors 10a, 10b, a hook-shaped slit, as illustrated, is formed at a bus bar 9a (likewise for the negative side) so that respective wiring inductance value from the positive (negative) terminal of the electrolytic capacitors 10a, 10b to positive (negative) terminals of the semiconductor modules 11a, 11b substantially equals each other, thus providing symmetry. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
