PROBLEM TO BE SOLVED: To provide a power conversion apparatus capable of easily replacing circuits constituting the apparatus while suppressing a charging current to an uncharged capacitor.SOLUTION: A conversion circuit module 1 includes: an IGBT 2a; an IGBT 2b connected to the IGBT 2a in series; a first terminal 12a connected to the IGBT 2a; a second terminal 12b connected to the IGBT 2b; a capacitor 4 connected to the first terminal 12a and the second terminal 12b; and a third terminal 12c connected to a node between the IGBT 2a and the IGBT 2b. A fourth terminal 6a is engaged with the first terminal 12a. A fifth terminal 6b is engaged with the second terminal 12b. A sixth terminal 6c is engaged with the third terminal 12c. The first and second terminals 12a, 12b respective have portions whose resistance is higher than that of the other portions between tips and ends.SELECTED DRAWING: Figure 2A 【課題】未充電のコンデンサへの充電電流を抑制しつつ、装置を構成する回路を容易に交換することができる電力変換装置を提供する。【解決手段】変換回路モジュール1は、IGBT2a、IGBT2aに直列接続されるIGBT2b、IGBT2aに接続される第１の端子12a、IGBT2bに接続される第２の端子12b、第１の端子12aと第２の端子12bに接続されるコンデンサ4、及びIGBT2aとIGBT2bの間の接続点に接続される第３の端子12cを有する。第４の端子6aは、第１の端子12aと係合する。第５の端子6bは、第２の端子12bと係合する。第６の端子6cは、第３の端子12cと係合する。第１及び第２の端子12a、12bは、先端から末端の間に他の部位よりも高抵抗な部位を有する。【選択図】図２Ａ
