US Patent 9413114 Three-level power converter

A 3-level power converter device with power semiconductor components including a first direct voltage positive potential terminal, a first direct voltage negative potential terminal, and first and second neutral voltage potential terminals. The first and second neutral voltage potential terminals are electrically conductively connected. The first direct voltage positive potential terminal and the first neutral voltage potential terminal form a first terminal pair, and the second neutral voltage potential terminal and the first direct voltage negative potential terminal form a second terminal pair. The first and second terminal pairs are arranged one behind another in a second direction. The first direct voltage positive potential terminal and the first neutral voltage potential terminal are arranged one above another in a third direction, and the second neutral voltage potential terminal and the first direct voltage negative potential terminal are arranged one above another in the third direction.
