A first electrode M1 that is connected to a higher-side potential portion of a first element pair 10, a second electrode M2 that is connected to a connection portion between a lower-side potential portion of the first element pair 10 and a higher-side potential portion of a second element pair 12, and a third electrode M3 that is connected to a lower-side potential portion of the second element pair 12, are provided on one of the main-surface sides of a module casing. The first electrode M1 and the third electrode M3 are arrayed in a direction orthogonal to a longitudinal direction of the module casing on one of the end sides in the longitudinal direction. The second electrode M2 is arranged on the other end side in the longitudinal direction of the module casing. Three dual-element triple-terminal power modules with the same configuration, configured as described above, are used to configure a three-level power converter of one phase. |
