Semiconductor module and power conversion device

Abstract

A semiconductor module (30) is contained in two inverters connected to a common rotating electrical machine. The semiconductor module (30) contains a semiconductor element (41), a semiconductor element (42), a current path (43), and a current path (44). The semiconductor element (41) is contained in the first inverter. The semiconductor element (42) is contained in the second inverter. The current path (43) contains the semiconductor elements (41). The current path (44) contains the semiconductor elements (42). In the X-direction, the semiconductor elements (41, 42) are arranged adjacent to each other, with at least a portion of their respective ON periods overlapping. The current paths (43, 44) are arranged side by side in the X-direction such that the respective directions of current flow through the current paths are opposite to each other.
