Abstract (en)
[origin: WO2019233585A1] Apparatus for converting an electrical DC voltage into an AC voltage. In order to provide an apparatus (15) for generating an AC voltage, having a first winding (16) which has winding segments (4, 5, 6) electrically insulated from one another, a second winding (17) which is inductively coupled to the first winding (16) via a magnetizable core (14), and two-pole submodules (7, 8, 9) which are connected in series with one another, wherein each submodule (7, 8, 9) forms, with one winding segment (4, 5, 6) in each case and power semiconductor switches (10), a bridge circuit which can be connected to a DC voltage connection, it is proposed that the first winding (16) is completely subdivided into winding segments (4, 5, 6) which are insulated from one another, wherein each winding element (4, 5, 6) is part of a two-pole submodule (7, 8, 9) and forms a bridge circuit with the power semiconductor switches (10).
