Abstract

A rectifier arrangement for rectifying an AC voltage into a DC voltage has connections, circuit arrangements, an interconnection apparatus and an intermediate circuit. Each circuit arrangement has first and second circuit arrangement connections, between which a changeover arrangement and a coil are connected in series with the changeover arrangement. The changeover arrangements are interconnected to the intermediate circuit. The interconnection apparatus is designed to enable at least a first configuration and a second configuration. In the first configuration, the circuit arrangements form a first group and a second group, with two connections connected to the circuit arrangements in the first group, but not to the circuit arrangements in the second group, and two connections are connected to the circuit arrangements in the second group, but not to the circuit arrangements in the first group. In the second configuration, at least one of the connections is connected to all circuit arrangements.
