Abstract: An electric power converter includes a semiconductor module and a DC bus bar. The semiconductor module includes a main body portion having a built-in semiconductor element therein and a DC terminal to which a DC voltage is applied projecting from the main body portion. A DC bus bar is connected to the DC terminal. The DC bus bar is disposed such that a thickness direction of the DC bus bar matches a projecting direction of the DC terminal. The penetrating portion penetrating the projecting direction is formed in the DC bus bar. The DC terminal is connected to the DC bus bar in a state where at least a part of the DC terminal is disposed in a position that can be seen from the penetrating portion when viewed from the projection direction. The penetrating portion is formed in a hole shape.

Abstract: An electric power conversion device has semiconductor modules, a main P bus bar, a main N bus bar, a capacitor module, an input P bus bar and an input N bus bar. The input N bus bar is connected to the DC power source. The main N bus bar is connected to a negative electrode terminal of the semiconductor module to supply the DC power. A capacitor N bus bar, a filter capacitor and a smoothing capacitor in the capacitor module are molded by capacitor molded resin. The capacitor N bus bar is connected to a negative electrode terminal of the filter capacitor. The input N bus bar has a first N connection section connected to the capacitor N bus bar and a second N connection section connected to the main N bus bar. The main N bus bar is arranged outside of the capacitor mold resin.

Abstract: An electric power conversion apparatus includes a stacked body, a capacitor, a metal frame and a case. The stacked body is formed by stacking semiconductor modules with coolant passages formed therebetween. The frame has both the stacked body and the capacitor fixed therein. The case has all of the stacked body, the capacitor and the frame received therein. Further, the frame has a separation wall that separates the stacked body and the capacitor from each other, a stacked body-surrounding wall that surrounds the stacked body with the help of the separation wall, and a capacitor-surrounding that surrounds the capacitor with the help of the separation wall. The capacitor has a pair of end portions that are opposite to each other in a predetermined direction, in which control terminals of the semiconductor modules of the stacked body protrude, and each at least partially exposed from the capacitor-surrounding wall of the frame.
