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.

Abstract: A power conversion circuit energization unit includes a bus bar module and a conductive fixing bolt. The bus bar module includes conductive P and N bus bars connected to a switch element in a power conversion device and an insulative terminal block on which the bus bars are located. The fixing bolt fixes the terminal block to a housing in which the switch element is housed. A head of the fixing bolt and the P bus bar are separated from each other in an axial direction along which a shaft of the fixing bolt extends while facing each other.

Abstract: An electric conductive part for a power conversion circuit includes a connection conductive portion and a branch portion. The connection conductive portion is configured to connect a joint portion of a battery with a capacitor that is included in the power conversion circuit. The connection conductive portion includes a path portion, which is configured to connect the joint portion with the capacitor, and a branch portion that branches from the path portion. The branch portion extends toward a control circuit board and is connected with the control circuit board. The control circuit board is configured to control drive of a switch element of the power conversion circuit.
