Title:
THREE-PHASE TRANSFORMER AND MULTI-STEP RECTIFIER USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/199666
Kind Code:
A1
Abstract:
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.
