Abstract
A semiconductor module, an upper and lower arm kit, and a three-level inverter can be provided at low cost and with broad current ratings and voltage ratings using existing packages, without developing new packages. A first semiconductor module () on an upper arm side and a second semiconductor module () on a lower arm side are made using an existing package, and the semiconductor modules () and () are used to configure an upper and lower arm kit (). Further, the upper and lower arm kit () is used to configure a three-level inverter (). These devices can be formed using existing packages (), and semiconductor modules (), (), the upper and lower arm kit (), and the three-level inverter () can be therefore provided at low cost and with broad current ratings and voltage ratings.
