Abstract: The invention relates to inverters employing a first and a second bridge circuit for converting DC input current into an AC output current. In particular, the invention proposes an inverter including two DC input terminals with a first and a second bridge circuit connected in parallel therebetween, the first bridge circuit for providing a first half-wave of a first polarity to a pair of AC output terminals and the second bridge circuit for providing a second half-wave of an opposite polarity to the pair of AC output terminals. The first half-wave is supplied from the first bridge circuit via a first and a second inductive element to the pair of AC output terminals, and the second half-wave is supplied from the second bridge circuit via a third and a fourth inductive element to the pair of AC output terminals.
