Abstract

Zum Schutz mehrerer Strings (2) eines Photovoltaikgenerators (3), die in Kleingruppen über jeweils einen DC/DC-Wandler (8) parallel an einen gemeinsamen Gleichspannungszwischenkreis (4) angeschlossen sind, vor Rückströmen wird der über jeden der DC/DC-Wandler (8) fließende Strom erfasst und ein auftretender Rückstrom (17) durch einen der DC/DC-Wandler (8) wird durch Ansteuern der DC/DC-Wandler (8) beendet.
