Abstract

In general, according to an embodiment, a power conversion apparatus (100) includes a first inverter (12), second inverter (22) and a cooler (2). The first inverter (12) includes a plurality of semiconductor devices (29 to 40) connected together in parallel per phase. In the second inverter (2), the number of parallel-connected semiconductor devices (41 to 46) are two or more per phase, the semiconductor devices are connected together in parallel and the number of parallel-connected semiconductor devices (41 to 46) in the second inverter (2) is fewer than that in the first inverter (12) per phase. The semiconductor devices (29 to 40) in the first inverter (12) are installed in an area of a cooling surface (56a) of the cooler (52) positioned over a first channel (57a). The semiconductor devices (41 to 46) in the second inverter (22) are installed in an area of the cooling surface (56a) positioned over the second channel (57b).
