Abstract
In an electric power converter, a stacked-layer unit has a plurality of semiconductor modules arrayed as layers along a stacking direction, each semiconductor module containing a semiconductor element and a pair of power terminals protruding outward in a protrusion direction at right angles to the stacking direction, each pair consisting of an AC terminal and a positive-polarity or negative-polarity power terminal. The semiconductor modules are arranged with the positive-polarity and negative-polarity power terminals in a single column at one side of the stacked-layer unit, and respectively connected to a positive-polarity busbar and negative-polarity busbar which are located at that side and which are separated by a fixed spacing in the protrusion direction, while the AC terminals of each layer-adjacent pair of semiconductor modules are connected in common to a corresponding one of a plurality of AC busbars.
