Abstract:
(EN) The present invention relates to a three-phase transformer comprising: first to third primary side coils to which first to third primary side voltages for first to third phases are applied respectively; first to third secondary side coils in which first to third secondary side voltages for the first to third phases corresponding to the first to third primary side voltages are induced and output respectively; and at least one iron core around which the first to third primary side coils and the first to third secondary side coils are wound, wherein: each set of the first primary side coil and the first secondary side coil corresponding to each other, the second primary side coil and the second secondary side coil corresponding to each other, and the third primary side coil and the third secondary side coil corresponding to each other has a spatial phase difference; and each of a magnitude of a temporal phase difference generated between the first primary side voltage applied to the first primary side coil and the first secondary side voltage applied to the first secondary side coil, a magnitude of a temporal phase difference generated between the second primary side voltage applied to the second primary side coil and the second secondary side voltage applied to the second secondary side coil, and a magnitude of a temporal phase difference generated between the third primary side voltage applied to the third primary side coil and the third secondary side voltage applied to the third secondary side coil is determined according to the spatial phase difference.
(FR) La présente invention concerne un transformateur triphasé comprenant : des première à troisième bobines côté primaire auxquelles des première à troisième tensions côté primaire pour des première à troisième phases sont respectivement appliquées ; des première à troisième bobines côté secondaire dans lesquelles des première à troisième tensions côté secondaire pour les première à troisième phases correspondant aux première à troisième tensions côté primaire sont respectivement induites et délivrées ; et au moins un noyau de fer autour duquel les première à troisième bobines côté primaire et les première à troisième bobines côté secondaire sont enroulées. Dans ladite invention, chaque ensemble de la première bobine côté primaire et de la première bobine côté secondaire correspondant l'une à l'autre, la deuxième bobine côté primaire et la deuxième bobine côté secondaire correspondant l'une à l'autre, et la troisième bobine côté primaire et la troisième bobine côté secondaire correspondant l'une à l'autre ont une différence de phase spatiale ; et chacune d'une amplitude d'une différence de phase temporelle générée entre la première tension côté primaire appliquée à la première bobine côté primaire et la première tension côté secondaire appliquée à la première bobine côté secondaire, une amplitude d'une différence de phase temporelle générée entre la deuxième tension côté primaire appliquée à la deuxième bobine côté primaire et la deuxième tension côté secondaire appliquée à la deuxième bobine côté secondaire, et une amplitude d'une différence de phase temporelle générée entre la troisième tension côté primaire appliquée à la troisième bobine côté primaire et la troisième tension côté secondaire appliquée à la troisième bobine côté secondaire est déterminée en fonction de la différence de phase spatiale.
