Abstract

a. Circuit de commande du courant traversant une bobine. b. Circuit caractérisé par un second circuit de commutation avec en parallèle un second circuit résonnant et une seconde bobine et un second condensateur, un second condensateur de charge branché en série sur la seconde bobine, un moyen pour brancher en série le premier et le second circuit résonnant sur l'alimentation, et un moyen pour appliquer un second signal de commutation de même fréquence que celle du premier signal de commutation au second circuit de commutation et un moyen pour modifier la phase entre le premier et le second signal de commutation et commander ainsi de façon différentielle la tension aux bornes du premier et du second condensateur de charge et par suite les courants traversant de façon différentielle la première et la seconde bobine.
