Abstract

L'invention concerne un transformateur de puissance haute-fréquence à large bande utilisable dans une bande de fréquence allant de 10 à 250 kHz environ. Un tel transformateur comporte un circuit magnétique fermé à trois branches en ferrite et des enroulements primaire et secondaire enroulés autour de la branche centrale de celui-ci. L'enroulement basse-tension est hélicoïdal et composé de plusieurs spires en un conducteur de section aplatie, tandis que l'enroulement haute-tension est composé de plusieurs galettes, intercalées chacune entre deux spires voisines de l'enroulement basse-tension, chacune de ces galettes comprenant deux ou plusieurs spirales plates superposées en un conducteur creux et refroidi. L'ensemble des enroulements est enrobé d'une résine élastique à base de silicones. Un tel transformateur est utilisable, notamment avec un générateur de hautes ou moyennes fréquences industrielles à triode.
