11. A converter system comprising:
at least two flying capacitor switching cells;
wherein each of the at least two flying capacitor switching cells comprises an arrangement of at least one semiconductor system; and
wherein the at least two flying capacitor switching cells are each arranged in a parallel circuit connection in an electrical circuit; and
wherein the at least two flying capacitor switching cells are configured such that a magnetic field of a first flying capacitor switching cell points in a different direction than a respective magnetic field of a second flying capacitor switching cell when the first flying capacitor switching cell is disposed in a first parallel circuit connection mirrored with respect to a second parallel circuit connection of the second flying capacitor, such that the first flying capacitor switching cell is in parallel to the second flying capacitor switching cell, and such that the first and second flying capacitor switching cells are situated adjacent to one another in the electrical circuit.
