Abstract
A DC-DC converter for connecting high-voltage DC networks has series-connected sub-converters. The high-voltage DC networks which can be connected to the DC-DC converter can have different transmission symmetries by way of power exchanging devices and additional power exchanging devices. Thus, a symmetrical monopole can be connected to an asymmetrical bipolar network using the invention.
