Abstract

L'invention se rapporte à un circuit électronique fournissant des signaux de declenchement en cas de surtension d'une alimentation. Ce circuit se caractérise par des moyens diviseurs de tension 110, 112, 114 et détecteurs de surcharge 116, 117 dans l'une ou l'autre polarité, actionnant des semi-conducteurs 54, 86, par des tensions appliquées à la fois à leurs portes et à leurs bornes principales, afin de décharger des condensateurs 68, 94 et produire les signaux de déclenchement b, a. L'invention s'applique notamment à des alimentations de lampes à décharge dans les gaz.
