Abstract

Un contrôleur de courant (42) compare un premier courant de bobine I circulant dans une bobine d'induction de sortie (L1) avec une première valeur de seuil supérieure I et une première valeur de seuil inférieure I . Un limiteur de courant (44) compare un second courant de bobine I circulant dans une bobine d'induction d'entrée (L2) avec une seconde valeur de seuil supérieure I et une seconde valeur de seuil inférieure I . Un contrôleur de cycle (46) (i) commute un transistor de commutation (M1) en se basant sur le premier courant de bobine I lors d'un cycle au cours duquel le premier courant de bobine I dépasse la première valeur de seuil supérieure I avant que le second courant de bobine I dépasse la seconde valeur de seuil supérieure I . Selon le contrôleur de courant (42), il est possible de stabiliser le courant de sortie et de limiter le courant.
