Abstract

Die Erfindung bezieht sich auf einen Transformator, insbesondere für einen Spannungskonverter umfassend eine Primärwicklung mit vorgebbarer Streuinduktivität und wenigstens eine mit der Primärwicklung in vorgegebenem Spannungs-Übersetzungsverhältnis magnetisch gekoppelte Sekundärwicklung.
Um bei einem solchen Transformator einen größeren Wert der (primären) Streuinduktivität zu ermöglichen, als es mit herkömmlichen Mitteln der Fall ist, ohne die Auslegungsgrenzen für einen funktionstüchtigen Transformator zu verletzen und ohne eine zusätzliche Spule oder einen größeren Kern als für die Leistungsübertragung erforderlich zu wählen, ist der vorstehende Transformator in der Weise ausgebildet, daß die Primärwicklung wenigstens zwei Wicklungsteile umfaßt, deren magnetische Kopplungen mit wenigstens einer der Sekundärwicklungen gegensinnig zueinander wirkend ausgebildet sind und die untereinander magnetisch wenigstens weitgehend entkoppelt angeordnet sind.
