Abstract: An electric power converter includes a semiconductor module with a built-in switching element, a cooler that cools the semiconductor module, and a metallic case provided with an internal space that accommodates the semiconductor module and the cooler. The case is formed by combining a first case member and a second case member. The case includes an outer fixing portion for connecting and fixing the first case member and the second case member on an outside of the internal space, an inner fixing portion for connecting and fixing the first case member and the second case member on an inside of the internal space. The case includes a partition wall that is formed continuously from the inner fixing portion and partitions the internal space. A heat-generating component disposed along a wall surface of the partition wall is accommodated in the internal space.

Abstract: The power converter includes a power conversion section which configures a circuit for power conversion, a power bus bar extending from the power conversion section, a terminal block, and a current sensor measuring current flowing in the power bus bar. The terminal block includes a mounting surface to which a terminal portion of the power bus bar is mounted. The mounting surface faces a direction substantially perpendicular to an arrangement direction in which the power conversion section and the terminal block are arranged. The current sensor is located at a side of a bottom surface on the opposite side of the mounting surface in the terminal block. The power bus bar includes: a sensor-surrounded portion surrounded by the current sensor; and an outer surface faced portion located between the sensor-surrounded portion and the terminal portion along an outer surface on the opposite side of the power conversion section.
