Abstract

Transformateur à flux variable permettant de faire varier la force électromotrice de sortie du secondaire. Il comprend un noyau de matériau conducteur du flux magnétique qui comprend trois branches partant d'une barre transversale commune et se terminant par des extrémités libres espacées. Des bobinages électriques primaire et secondaire sont associés aux deux premières branches. La troisième branche permet de fermer un circuit magnétique qui part de la branche portant le primaire et qui shunte la branche portant le secondaire. Un commutateur de commande, qui est aussi en matériau conducteur du flux magnétique, est disposé aux extrémités libres des branches et les relie selectivement de manière à ne fermer entre elles que des circuits de faible réluctance à un moment donné quelconque. Application aux transformateurs à force électromotrice de sortie variable tels que des transformateurs différentiels.
