In a method and a device for continuously adjusting, within a certain adjustment range, the turns ratio between the primary (4) winding and the secondary (6) winding of a power transformer (2) provided with at least one regulating winding, a first tap (6a, 6b, 6c, 6d) is switched on during a portion of a cycle of the alternating voltage of the transformer (2) and a second tap (6b, 6c, 6d, 6a) is switched on during another portion of the cycle of the alternating voltage. For this purpose, the device comprises electronic switches (8a, 8b, 8c, 8d, 10a, 10b, 10c, 10d) in the form of thyristors or transistors.
La présente invention concerne un procédé et un dispositif permettant de régler en continu, dans les limites d'une plage de réglage déterminée, le rapport de spires entre le primaire (4) et le secondaire (6) d'un transformateur électrique (2) équipé d'au moins un enroulement de régulation. Le procédé consiste à commuter un premier conducteur (6a, 6b, 6c, 6d) pendant une partie d'un cycle de tension alternative du transformateur (2), un second conducteur (6b, 6c, 6d, 6a) étant commuté pendant l'autre partie du cycle de tension alternative. Pour ce faire, le dispositif est muni de commutateurs électroniques (8a, 8b, 8c, 8d, 10a, 10b, 10c, 10d) réalisés sous forme de thyristors ou de transistors.
