Abstract
A device controls a power flow in an AC network and has a series converter with a DC side to connect to a DC link and an AC side to connect to the AC network via a series transformer. The device further has a bridging arrangement between the series transformer and the series converter configured to bridge the series converter. The bridging arrangement contains at least one bridging branch having a switching unit with antiparallel thyristors and a resistance in series with the switching unit. Furthermore, a method of operation operates the device.
