1. A power converter configuration, comprising:
a modular multilevel power converter containing a series connection of switching modules each having a plurality of semiconductor switches, connection terminals, and at least one energy storage unit, wherein some of said switching modules are switching modules of a first type and some others of said switching modules are switching modules of a second type, wherein, during operation of the power converter configuration, in each case a positive switching module voltage, a negative switching module voltage or a zero voltage being generated at said connection terminals of said switching modules of the first type, and in each case a positive switching module voltage or a zero voltage being generated at said connection terminals of said switching modules of the second type; and
a support structure containing a plurality of levels each having receptacles in which said switching modules are disposed, wherein said switching modules of both the first type and the second type are disposed in each of said levels of said support structure.
