Abstract

A power converter arrangement includes a first converter and a second converter which include each an intermediate voltage circuit and a load-side converter. The intermediate voltage circuit of the first converter is connected electrically to the intermediate voltage circuit of the second converter by a connecting line. The connecting line is connected to a node point either with three partial connecting lines when the load-side power converters include two half-bridges, or with four partial connecting lines when the load-side power converters includes three half-bridges. Each of the partial connecting lines has at least one semiconductor component for generating a voltage drop.
