Abstract
A commutation cell for a flying capacitor module, to a flying capacitor module having the commutation cell and to a multi-level converter having the flying capacitor module is disclosed. The commutation cell includes a circuit board, two semiconductors mounted either on the same side or on opposite sides of the circuit board, four capacitors arranged in pairs on opposite sides of the circuit board, and flying capacitors connected to the input and output sides of the commutation cell, respectively. The capacitors located on opposite sides are connected to one another by way of via holes. Different commutation paths between the various capacitors extend on the first side and on the second side of the circuit board and along the vias, with currents flowing through the respective adjacent capacitors in opposing directions for an overall reduction in the parasitic inductances.
