The invention relates to an inverter or an output filter for inverters. The output current of a high-performance inverter usually comprises a series of harmonic components of the current. Said harmonic components are disturbing and are inconvenient if higher capacities have to be supplied to a network via an inverter. The aim of the invention is therefore to remove the above-mentioned drawbacks so that the current is supplied with very few, if possible none at all, harmonic components. Another aim is to stabilize the DC link of the inverter in its electric potential (voltage to the housing, to the ground or to the three-phase current system). To this end, the invention provides an inverter for producing an AC or three-phase current from a direct current. Said inverter comprises a DC link and an output choke (LA) at the output. Harmonic components that occur at the output are coupled into the DC circuit. |
