Power supply assembly with an inverter for creating single phase alternating current

Power supply arrangement with an inverter (3) generating single-phase AC current and a transformer (4) having a primary winding (41) and a first secondary winding (421) and a second secondary winding (422), wherein the secondary windings (421, 422) have the same number of turns and are arranged so that they are permeated by the same magnetic flux during operation of the transformer (4), so that identical voltages can be tapped at the secondary windings (421, 422) during the operation of the transformer (4), wherein a respective terminal of the first secondary winding (421) and a respective terminal of the second secondary winding (422) are connected to one another at a first point (K1), that a two-phase system whose phases are shifted by 1800 relative to each other is produced between the first point (K1), an additional terminal of the first secondary winding (421); and an additional terminal of the second secondary winding 422), wherein the first point (K1) is connected to a neutral conductor terminal (N) of
