Abstract: A power module is applied to an electric power conversion device in which multiple upper-lower arm circuits are connected to an electric power line in parallel. The power module includes the multiple upper-lower arm circuits; a capacitor connected to each of the multiple upper-lower arm circuits in parallel; an upper wiring that connects an upper arm and a positive electrode terminal of the capacitor; a lower wiring that connects a lower arm and a negative electrode of the capacitor; an upper electric power wiring that is an electric power wiring connected to the electric power line and connects a high potential line of the electric power line and the upper wiring; and a lower electric power wiring that is an electric power wiring connected to the electric power line and connects a lower potential line of the electric power line and the lower wiring.

Abstract: A power converter includes a heat generator configured to generate heat through power conversion, and a case housing the heat generator. The case includes a case member that is made of resin and defines an opening, and a cooler that is made of metal and disposed to cover the opening. The cooler includes a cooling water passage for cooling the heat generator. The case member includes an upper case member that defines an upper opening to be covered by a cover member, and a lower case member that defines the opening covered by the cooler. One of the upper case member and the lower case member has an input side attachment portion to be attached to an input terminal and the other of the upper case member and the lower case member has an output side attachment portion to be attached to an output terminal.
