Abstract
A power conversion apparatus includes N semiconductor modules respectively including a switch part including first and second semiconductor switches coupled in series, and an output terminal coupled to a node that connects the first and second semiconductor switches, where N is an integer greater than or equal to 3, wherein the N semiconductor modules are arranged so that the output terminals thereof are adjacent to each other. The power conversion apparatus further includes an output bar to couple the output terminals of the N semiconductor modules so that a parasitic inductance of a current path coupling the output terminals of first and second semiconductor modules among the N semiconductor modules, and a parasitic inductance of a current path coupling the output terminals of the first and third semiconductor modules among the N semiconductor modules, are approximately balanced.
