An electric adjuster is designed to permit an a.c. power supply or an a.c. signal as an input to be arbitrarily adjusted or converted with high efficiency and outputted. The ratio of windings of a transformer can be arbitrarily adjusted or continuously adjusted. If the number of primary coils is 6, as a first example, the electric adjuster includes a transformer (3) having a secondary coil (37) and a plurality of primary coils (31), (32), (33), (34), (35) and (36) whose ratios of windings to the secondary coil (37) are 1, 2, 4, 8, 16 and 32, respectively, and a coil switching operation section (2) that switches the combinations of the primary coils (31) to (36) using a plurality of switches (21), (22), (23), (24), (25), (26), (27), (28), (29), (210), (211) and (212), to make the number of composite windings variable, with the result that the ratio of primary windings to secondary windings is continuously digitally adjusted. In a second embodiment, one primary coil and a plurality of secondary coils are used. In a third embodiment, a plurality of primary coils and a plurality of secondary coils are used.
Dispositif d'ajustage électrique permettant de régler arbitrairement ou en continu le rapport de spires d'un transformateur de façon à régler ou convertir au choix et efficacement une tension ou des signaux CA en d'autres tensions ou signaux CA. Un appareil de ce dispositif d'ajustage se compose par exemple d'un transformateur (3) à six enroulements primaires (31 à 36) et à un enroulement secondaire (37), dans lequel les enroulements primaires (31 à 36) présentent respectivement des rapports de spires (1, 2, 4, 8, 16 et 32) plus élevés que ceux de l'enroulement secondaire (37), et d'une partie commutateur (2) d'enroulements qui ajuste numériquement et en continu les rapports entre le nombre de spires d'enroulements primaires et celui de l'enroulement secondaire en commutant la combinaison des enroulements primaires à l'aide des commutateurs (21, 22, 23, 24, 25, 26, 27, 28, 29, 210, 211 et 212) et en modifiant par là le nombre des spires sur le côté primaire.
