Power converter
A power converter includes: a plurality of power modules that houses semiconductor elements for electric power conversion; a pair of holding plates sandwiching a stacked body of the plurality of power modules in the first direction; a pair of connecting beams that connects the pair of holding plates respectively on both side ends of the stacked body in the second direction intersecting the first direction; and a substrate connected to control terminals of the power modules. At least one of the pair of holding plates is provided with a positioner to position the substrate.
1. A power converter comprising:
a plurality of power modules that houses semiconductor elements for electric power conversion;
a pair of holding plates sandwiching a stacked body of the plurality of power modules in a first direction;
at least one elastic member;
a pair of connecting beams that connects the pair of holding plates at respective side ends of the stacked body in a second direction intersecting the first direction, each of the pair of connecting beams being divided into a first divided beam and a second divided beam in the first direction, the first divided beams and the second divided beams being connected to each other by the at least one elastic member;
a substrate connected to control terminals of the power modules, the control terminals extending in a third direction intersecting both the first direction and the second direction, the substrate being adjacent to the stacked body in the third direction; and
a positioner to position the substrate provided with at least one of the pair of holding plates.
