| 摘要 |
This inverter device is equipped with: power modules (3) each having at least one arm of an inverter circuit (10); a plate-like direct-current bus substrate (5) on which smoothing capacitors (40), which are connected between a positive electrode (P) and a negative electrode (N) of a direct-current power supply, are fixed; and a fixing member (7) for fixing the relative positional relation between the power modules (3) and the direct-current bus substrate (5). Positive connection terminals (55P) of the direct-current bus substrate (5) and positive terminals (3P) of the power modules (3) are fastened to the fixing member (7) by means of common fastening members (9), and negative connection terminals (55N) and negative terminals (3N) are fastened to the fixing member (7) by the common fastening members (9) such that the power modules (3) and the smoothing capacitors (40) are fixed in a small space. |
