POWER SUPPLY ARRANGEMENT WITH INVERTER FOR GENERATING SINGLE-PHASE AC CURRENT

PROBLEM TO BE SOLVED: To provide a power supply arrangement which can avoid differences between voltage values at output parts.SOLUTION: A power supply arrangement comprises: an inverter 3 for generating a single-phase AC current; and a transformer 4 having a primary coil 41, a first secondary coil 421 and a second secondary coil 422. The secondary coils 421, 422 have the same number of turns and are arranged to be permeated by the same magnetic flux during operation of a transformer 4, so that identical voltages can be tapped at the secondary coils during operation of the transformer 4. A terminal of the first secondary coil 421 and a terminal of the second secondary coil 422 are connected to one another at a first point K1, so that a two-phase system whose phases are shifted by 180° relative to each other is produced between first point K1, an additional terminal of the first secondary coil 421 and an additional terminal of the second secondary coil 422. The first point K1 is connected to a neutral conductor terminal N of an output part of the power supply arrangement via a capacitor.
