POWER SUPPLY SYSTEM WITH AN INVERTER FOR GENERATION OF SINGLE-PHASE ALTERNATING CURRENT

Provided is a power supply system comprising: an inverter (3) for generating single phase alternate current; and a transformer (4) including a primary winding (41), a first secondary winding (421) and a second secondary winding (422). The secondary windings (421, 422) have the same number of windings, and are arranged such that the same voltage is tapped at the secondary windings (421, 422) while the transformer (4) is being operated because the same magnetic flux flows through the secondary windings (421,422). One contact part of the first secondary winding (421) is connected to one contact part of the second secondary winding (422) at a first point (K1). Two phase systems are positioned between the first point (K1) and the other contact part of the first secondary winding (421), and between the first point (K1) and the other contact part of the second secondary winding (422). The phases of the two phase systems are 180 degrees shifted relative to each other. The first point (K1) is connected to a neutral line contact part (N) of an output part of the power supply system via a capacitor.
