Patent ID: 8724313

Claim:
A power conversion apparatus, comprising: electronic components constituting a power conversion circuit; a cooler which works to cool at least a portion of the electronic components; an internal unit having a frame to which the at least a portion of the electronic components and the cooler are secured and which surrounds the at least a portion of the electronic components; a case in and to which the internal unit is disposed and fixed through the frame; and; a capacitor that is one of the electronic components and with which the internal unit is equipped, wherein the frame includes unit fixing sections through which the internal unit is fixed to the case and capacitor fixing sections through which the capacitor is fixed to the internal unit, wherein the capacitor fixing sections are located inward of the frame more than the unit fixing sections, wherein the internal unit has a plurality of semiconductor modules disposed inside the frame as ones of the electronic components, the semiconductor modules having switching elements installed therein, wherein the semiconductor modules are equipped with a main electrode terminal into or from which controlled electric power is inputted or outputted and which protrudes toward the capacitor, and wherein the capacitor fixing sections protrude from the frame toward the capacitor to have a top end located farther away from the frame than a top end of the main electrode terminal.
