Abstract

Appareil de détection des diodes défectueuses (coupées ou court-circuitées) d'un pont de redressement à diodes. Appareil comprenant : un pont de détection à diodes semblable au pont de redressement; un moyen résistif associé aux deux ponts pour procurer une tension de neutre virtuel; et un agencement détecteur connecté aux deux ponts ainsi qu'au moyen procurant la tension de neutre virtuel et sensible aux tensions délivrées par ces trois éléments pour détecter des relations prédéterminées entre, d'une part, les tensions délivrées par les deux ponts et, d'autre part, la tension de neutre virtuel et celle délivrée par le pont de redressement.
