Abstract

A modular power converter with wide-bandgap semiconductors, in particular SiC semiconductors. The modular power converter has at least two base units. The base units are connected together on the input side, and each base unit has an input circuit on the input side and an output circuit on the output side. The input circuit and the output circuit are each formed by the wide-bandgap semiconductors arranged in a B6-bridge circuit. An intermediate circuit capacitor is connected in parallel with the input circuit and the output circuit forming an intermediate circuit. The input circuits of the base units or a sub-quantity of the base units are arranged in a series circuit. At least one inductor is arranged between each pair of input circuits.
