Abstract:
     This invention relates to the field of electrotechnology. It changes the conventional single-layer winding structure on the annular core of the autotransformer. As a result of using the structure of multilayer winding, the cross-sectional coefficient of the core and the hatch filling factor are raised, power output is doubled and loss is reduced. It is suitable to voltage-regulating for the range of 0-250 v in single phase and 0-500 v in three-phase.
