Abstract

A DC converter is suitable for continuous operation for connecting high-voltage DC networks having different voltages. The DC converter has a first partial converter and a second partial converter, which are connected in series with each other, forming a converter series circuit. The converter series circuit extends between the DC terminals of a DC connection. The second partial converter extends between the DC terminals of a second DC connection. The first partial converter and the second partial converter are connected to each other via a power exchange device, such that the exchange of electrical power between the first partial converter and the second partial converter is made possible via the power exchange device.
