Abstract
A circuit for balancing capacitor voltages at capacitors in a DC circuit includes a first circuit path having first and second capacitors connected in series between first and second potentials of a DC voltage of the DC circuit, with a first center tap arranged between the first and second capacitors. A second circuit path includes first and second switchable semiconductors and first and second balancing elements which are connected in series between the first and second potentials. The first switchable semiconductor is arranged at the first potential, the second switchable semiconductor at the second potential, and the first and second balancing elements are arranged between the first and second switchable semiconductors, with a second center tap arranged between the balancing elements. A first electrical connection is established between the first center tap in the first circuit path and the second center tap in the second circuit path.
