The metallic case of a power conversion apparatus includes a casing having a side wall, as well as an upper case and a lower case, a first area being formed between a cooling jacket provided at the inner periphery of the side wall and the lower case, the metal base plate dividing the first area between the cooling jacket and the upper case into a lower side second area and an upper side third area, first and second power modules being fastened to a top surface and a capacitor module being provided in the first area, driving circuits that drive inverter circuits of the power modules respectively being provided in the second area, and a control circuit that controls the driver circuits being provided in the third area.
First claim
Opening claim text (preview).
What is claimed is: 1. A power converter apparatus comprising: a power module having a power semiconductor element; a metal base; a driving circuit board disposed between the power module and the metal base; a control circuit board fastened at one side of the metal base opposite to the driving circuit board; a casing holding the power module and being formed integrally with a cooling jacket flowing a cooling liquid; and a first heat releasing part disposed between the metal base and the driving circuit board, wherein the first heat releasing part contacts the metal base and the driving circuit board, and the metal base contacts with the casing. 2. The power converter apparatus according to claim 1 , wherein the casing has a first flange, and the metal base contacts with the first flange. 3. The power converter apparatus according to claim 1 , further comprising: a second heat releasing part disposed between the metal base and the control circuit board, wherein the second heat releasing part contacts the metal base and the control circuit board.
