Abstract
A power semiconductor module includes: a positive arm and a negative arm that are formed by series connection of self-arc-extinguishing type semiconductor elements, the positive arm and the negative arm being connected at a series connection point between the self-arc-extinguishing type semiconductor elements; a positive-side electrode, a negative-side electrode, and an AC electrode connected to the positive arm and the negative arm; and a substrate on which a plurality of wiring patterns are formed, the wiring patterns connecting the self-arc-extinguishing type semiconductor elements of the positive arm and the negative arm to the positive-side electrode, the negative-side electrode, and the AC electrode. Respective directions of current flowing in adjacent wiring patterns are identical to each other, and one of the adjacent wiring patterns is arranged in mirror symmetry with the other of the adjacent wiring patterns.
