Abstract

A power converter may include a first and second housings, each of which houses switching elements connected in parallel. Each of the first and the second housings may be provided with a first surface and a second surface. The first and the second housings may be arranged face to face. In each of the first and the second housings, the switching elements may be aligned in an alignment direction which is parallel to both of the first and the second surfaces. An emitter terminal or a source terminal of parallel connection of the switching elements may extend from the second surface at a position equidistant from the switching elements positioned at both ends in the alignment direction among the plurality of switching elements. A collector terminal or a drain terminal of the parallel connection may be positioned adjacent to the emitter or the source terminal in the alignment direction.
