Description
Wie bereits vorerwähnt wird durch Veränderung des Ausgangspotentials des Operationsverstärkers 2 6 der Zeitpunkt bestimmt, bei dem der über das Rückkoppelnetzwerk 34 und die Basis des 0 Schalttransistors 10 fließende Steuerstrom über den Kondensator 32 abgeleitet wird. Ein höheres Spannungspotential bedeutet einen späteren AbschaltZeitpunkt und ein demgegenüber niedrigeres Ausgangspotential, dementsprechend ein längeres Ansteuersignal für den Schalttransistor 10.
5 Entsprechend dem Spannungs-Stromdiagramm gemäß Figur 4 wird nun
