PURPOSE:To obtain a single phase AC feeding system in which an unbalanced voltage is not generated among three phases. CONSTITUTION:The single phase AC feeding system comprises a Scott connection transformer for converting three-phase AC into two-phase AC, a converter 5 connected at its input terminal at first side seat of a secondary side of the transformer to its input terminal to convert a secondary side voltage into a DC, an inverter 8 connected at its input terminal to the output terminal of the converter 5 to convert the DC output into an AC, and a transformer 9 connected at its primary side to the output terminal of the inverter 8, at its secondary side to a second side seat of the transformer to transform the output voltage of the inverter 8 to supply it to a load connected to its secondary side. |
