Abstract
A power conversion apparatus includes a plurality of semiconductor modules each with a power terminal protruding therefrom, a capacitor, and a pair of bus bars. The power terminals include a pair of DC terminals electrically connected to the capacitor via the bus bars, and an AC terminal. Each of the bus bars includes terminal connection portions welded to the respective DC terminals and a common portion electrically connected to the plurality of terminal connection portions. The common portions are arranged between the sets of the plurality of power terminals. An insulation member is interposed between the pair of common portions. High-thermal-resistance portions having a higher thermal resistance than the terminal connection portions are each formed between the corresponding terminal connection portion and the corresponding common portion.
