Abstract

The invention relates to a circuit arrangement for producing an alternating voltage or an alternating current from a unipolar direct current source having an inverter relating to a neutral conductor. The direct current source is connected to an inverter which converts the unipolar voltage of the direct current source into a bipolar intermediate circuit voltage that is stored in a buffer circuit (C1, C2) which is connected to the inverter. The inverter comprises a clocked switch (So) and an energy converting unit which is configured as a dual coil (DR1,DR2) having two windings (W1,W2) which are closely coupled to each other.
