Fraunhofer ISE entwickelt hochkompakten Wechselrichter zur Direktanbindung ans Mittelspannungsnetz

(PresseBox) (Freiburg, )
Mit voranschreitender Energiewende wird der Ausbau der Stromnetze zunehmend wichtiger. Immer mehr regenerative Erzeugungsanlagen sowie elektrische Speicher werden an das Netz angeschlossen. Dadurch kommt der Leistungselektronik eine entscheidende Rolle zu, weil sie zur Ankopplung dieser Systeme an das Netz notwendig ist. Neben der reinen Einspeisung bzw. Rückspeisung von elektrischer Energie muss die Leistungselektronik aber noch weitere netzstützende Aufgaben übernehmen. Im Projekt »SiC-MSBat« haben Forschende des Fraunhofer-Instituts für Solare Energiesysteme ISE nun gemeinsam mit Partnern einen hochkompakten Wechselrichter zur direkten Einspeisung in das Mittelspannungsnetz entwickelt und erfolgreich in Betrieb genommen.

Aktuell speisen Wechselrichter meist in das Niederspannungsnetz ein. Über große 50-Hz-Transformatoren
