Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben eines Wechselrichters (3), der zur Einspeisung von elektrischer Energie über einen Transformator (4) an ein Energieversorgungsnetz (7) angeschlossen ist, wobei Ausgangsströme (ia, ib, ic) und Ausgangsspannungen (Va, Vb, Vc), des Wechselrichters erfasst werden und Leistungsschalter des Wechselrichters (3) anhand von Steuersignalen geschaltet werden, wobei die Steuersignale in Abhängigkeit von den Ausgangsströmen (ia, ib, ic) und Ausgangsspannungen (Va, Vb, Vc) bei einer Grundfrequenz des Energieversorgungsnetzes (5) erzeugt werden. Das Verfahren zeichnet sich dadurch aus, dass die Steuersignale zusätzlich mittels eines Regelkreises (36) mit positiver Rückkopplung in Abhängigkeit von einer Oberschwingung der Ausgangsspannungen (Va, Vb, Vc) des Wechselrichters (3) mit einem Vielfachen der Grundfrequenz erzeugt werden. Die Erfindung betrifft weiterhin einen zu Durchführung des Verfahrens eingerichteten Wechselrichter (3).
