Abstract

Ce circuit pour engendrer une onde de courant en dents de scie dans un bobinage comprend un circuit résonnant parallèle comportant un bobinage L et deux condensateurs C1 et C2 montés en parallèle. Une première diode D1 est connectée en parallèle avec l'un des condensateurs C2 et un transistor de commutation T1 monté en parallèle avec la diode D 1 est relié par l'intermédiaire d'une seconde diode D2 à la cathode de la première diode D1 . L'énergie d'entrée provenant d'une source d'alimentation Vb est appliquée à la jonction entre la seconde diode D2 et le transistor de commutation T1 par l'intermédiaire d'une bobine inductive La qui constitue un circuit résonnant avec un autre condensateur C 3 faisant partie d'un circuit à réactance disposé en parallèle avec la seconde diode D2 .
