Abstract

La source d'énergie comprend un générateur de courant 11 et une capacité C1 alimentée par Ce générateur de courant. Un organe de commande 10 pilote deux interrupteurs T1 et T2, dont le premier T1 commande pendant la phase d'appel la décharge de la capacité C1 dans la première bobine L1, et dont le deuxième T2 établit pendant la phase d'appel et pendant la phase de maintien, le passage du courant dans la deuxième bobine L2. Le niveau de courant requis du générateur de courant est ainsi réduit.
