Abstract

Zur Anpassung der Schaltfrequenz in einem Umrichter wird ein Schaltsignal zu einem Schaltzeitpunkt t2 derart erzeugt, dass der erwartete Nulldurchgang des Lastkreissignals (13) zum Zeitpunkt t3 bestimmt wird und davon die Schaltzeit toff abgezogen wird. Der Schaltzeitpunkt t2 eilt somit dem erwarteten Nulldurchgang des Lastkreissignals (13) um die Schaltzeit toff vor. Der Umrichter wird dabei so angesteuert, dass die Schaltverluste minimiert werden.
