Abstract

Dispositif, système et procédé pouvant trouver application dans un circuit commandé biphasé de commutation adapté pour fournir une charge. On traite des signaux de retour (17, 18) associés au courant passant dans la charge, et on les utilise pour commander les dispositifs commutateurs (5, 6) du circuit de commutation. Le signal de retour est en phase avec la tension appliquée à la charge aux bornes du circuit de commutation. On traite ces signaux de retour pour former un signal que l'on combine ensuite à un signal de référence. On utilise le résultat ainsi obtenu pour commander un modulateur de largeur d'impulsion produisant un signal à modulation de largeur d'impulsion. On utilise la polarité du signal de référence pour diriger le signal modulé en largeur d'impulsion vers les entrées de commande (15, 16) des dispositifs commutateurs. De préférence, on compare une tension de référence à un signal secondaire dépendant de la tension dans la charge. Ainsi, on peut régler le signal modulé en largeur d'impulsion de manière à compenser les variations de l'impédance de la charge.
