Converter system having converter modules connected by a DC intermediate circuit, and method for operating such a system

Converter system having converter modules connected by a DC intermediate circuit, and method for operating such a system

DC intermediate circuit capacity (C1-C5), is divided into sections corresponding in number with the number of converter modules (13-17). Each module is allocated a fraction of the DC intermediate circuit capacity forming a local intermediate circuit. The modules and their local intermediate circuits...

Zusammenfassung:DC intermediate circuit capacity (C1-C5), is divided into sections corresponding in number with the number of converter modules (13-17). Each module is allocated a fraction of the DC intermediate circuit capacity forming a local intermediate circuit. The modules and their local intermediate circuits are connected through at least one protective switch (S1-S5), especially a semiconductor switch, to the DC voltage bus bars (11, 12). An Independent claim is included for a corresponding method of operation.
