Claims (7)

  1. Bloc d'alimentation et de commutation avec un transformateur (2) sur le côté secondaire duquel on obtient une tension de réglage (Ur1) qui est transférée au primaire et qui y est appliquée, pour stabiliser les tensions de fonctionnement (U1, U2) produites sur le secondaire, à une borne de commande (a) d'un circuit de commande (4) pour le transistor de commutation (T1) qui est couplé en série avec l'enroulement primaire (3), caractérisé en ce que le trajet de transmission de la tension de réglage (Ur1) sur le primaire est appliqué à l'entrée de commande d'un étage de commutation (22-24) qui se trouve entre la borne de commande (a) du circuit de commande (4) et une borne (c) avec une seconde tension de réglage (Ur2) produite sur le primaire qui, en cas de défaillance de la première tension de réglage (Ur1), arrive à la borne de commande (a) du circuit de commande (4) par l'étage de commutation commandé en étant efficace (22-24) et qui règle les tensions de fonctionnement (U1, U2) à des valeurs diminuées.
  2. Bloc d'alimentation selon la revendication 1, caractérisé en ce que la tension de réglage (Ur1) obtenue sur le secondaire est transformée dans un modulateur (10-12) en une tension d'impulsion, que celle-ci est transférée au primaire par un transformateur supplémentaire (15) et qu'elle y est redressée à nouveau (17).
  3. Bloc d'alimentation selon la revendication 2, caractérisé en ce que la tension d'impulsion à moduler est dérivée par un enroulement secondaire (6) du transformateur (2) du bloc d'alimentation et de commutation.
  4. Bloc d'alimentation selon la revendication 1, caractérisé en ce qu'un point de commutation (c, d) qui conduit la seconde tension de réglage est relié à la borne de commande (a) par une diode (22) bloquée en fonctionnement normal.
  5. Bloc d'alimentation selon la revendication 2 et 4, caractérisé en ce que le point de commutation (c, d) est mis à la terre par le montage en parallèle d'un condensateur (23) et d'un transistor (24) à la base duquel la tension d'impulsion de l'enroulement côté primaire (16) du transformateur supplémentaire (15) est appliquée.
  6. Bloc d'alimentation selon la revendication 1, caractérisé en ce que les valeurs réduites se situent jusqu'à 10 % au-dessous des valeurs nominales.
  7. Bloc d'alimentation selon la revendication 1, caractérisé en ce qu'un indicateur (diode électroluminescente) est prévu pour l'état de fonctionnement avec la seconde tension de réglage (Ur2).
