Abstract: A power converter is equipped with a semiconductor module stack, a positive bus bar stack, and a negative bus bar stack. The positive bus bar stack has a first positive bus bar and a second positive bus bar stacked. The negative bus bar stack also has a first negative bus bar and a second negative bus bar stacked in a stacking direction Z of the positive bus bar stack. The first semiconductor modules of the semiconductor module stack are connected to the first positive bus bar and the first negative bus bar, while the second semiconductor modules of the semiconductor module stack are connected to the second positive bus bar and the second negative bus bar. This results in a decreased variation in mutual inductance among the semiconductor modules, which leads to a decrease in overall inductance of the power converter.

Abstract: In a power conversion apparatus, an inverter converts a DC voltage supplied from a battery into an AC voltage, and a DC-to-DC converter steps up or down the DC voltage. A case has an input terminal to which a power line from the battery is connected so as to input the DC voltage to the inverter, and a converter input terminal to which a power line to the DC-to-DC converter is connected so as to input the DC voltage to the DC-to-DC converter. The case has a reference wall and an opposed wall opposed to each other. The inverter input terminal is disposed adjacent to the reference wall with respect to an imaginary plane that bisects the case between the reference wall and the opposed wall. The converter input terminal is disposed adjacent to the opposed wall with respect to the imaginary plane.
