Abstract
A three-level power converter includes a first module housing a vertical arm forming a three-level power conversion circuit; a second module disposed adjacent to the first module and housing an intermediate arm forming the three-level power conversion circuit; high-potential and low-potential connecting terminal boards each extending vertically, and having a lower end connected to connecting terminals on an upper surface of the first module, and an upper end provided with an external connecting end; and a flat intermediate-potential connecting terminal board extending vertically, and having a lower end connected to connecting terminals on an upper surface of the second module, and an upper end provided with an external connecting end. The high-potential, low-potential, and intermediate-potential connecting terminal boards are stacked close to and parallel to one another. Each of the external connecting ends is connected to a corresponding terminal of a DC capacitor.
