Abstract

Un variateur électronique destiné à piloter un circuit d’alimentation électrique basse tension d’une charge, comprend un dispositif de commande pilotant au moins un interrupteur à base de transistor connecté à deux broches, les deux broches étant destinées à connecter en série le variateur électronique sur le circuit d’alimentation de la charge. Il comprend en outre un dispositif de protection comprenant un circuit crowbar disposé en parallèle dudit interrupteur à base de transistor. Figure à publier avec l’abrégé : Fig. 1An electronic variator intended to control a low voltage electrical power supply circuit of a load, comprises a control device controlling at least one transistor-based switch connected to two pins, the two pins being intended to connect the electronic variator in series. on the load supply circuit. It further comprises a protection device comprising a crowbar circuit arranged in parallel with said transistor-based switch. Figure to be published with the abstract: Fig. 1
