Abstract:
1. An electric power conversion apparatus, comprising: a plurality of semiconductor modules, with each of the plurality of semiconductor modules including a power semiconductor device for converting a direct current to an alternating current; a driver board that includes a driver IC for driving the power semiconductor devices; a capacitor module that includes a capacitor for smoothing the direct current; and a channel forming body configured to form a first channel and a second channel through which a refrigerant flows, wherein: the first channel is disposed at a side of the capacitor module; the second channel is disposed at another side of the capacitor module, opposite to the first channel; one or more first semiconductor modules among the plurality of semiconductor modules are disposed in and fixed to the first channel and one or more second semiconductor modules among the plurality of semiconductor modules are disposed in and fixed to the second channel; the driver board is arranged above the capacitor module and extended to a region facing the first semiconductor modules in the first channel and a region facing the second semiconductor modules in the second channel; and the driver IC is disposed in a region facing to the capacitor module.
