Abstract

Le dispositif de l'invention est du type comprenant au moins une paire de commutateurs à semi-conducteurs connectés en série avec une alimentation en courant continu et disposés pour agir séquentiellement par une série de signaux de commande de << fermeture >> et << d'ouverture >> pour alimenter une charge, et de moyens destinés à fournir un intervalle de retard entre la commande << d'ouverture >> à l'un quelconque des commutateurs, et la commande << de fermeture >> du commutateur suivant en séquences. Il est caractérisé par le fait qu'on prévoit des moyens 7, 11, 19 pour détecter le moment où deux commutateurs successifs dans la séquence sont rendus conducteurs simultanément et des moyens 14, 15 pour augmenter la durée de l'intervalle de retard lorsqu'un tel état conducteur simultané est détecté Application aux émetteurs, notamment.
