Abstract

The circuit arrangement has a first full bridge branch containing a series circuit with first and third electronic switches (S1,S3) connected at a center point (N1), a second full bridge branch containing a series circuit with second and fourth electronic switches (S2,S4) connected at a second center point (N2). The first and second full bridge branches are connected to positive and negative nodes (N3,N4). A storage capacitor (C6) is connected between the nodes. The first and second center points are connected by a choke (L1). At least one second choke (L2) is connected in the second full bridge branch in series with the second and fourth electronic switches.
