    An autotransformer is a transformer with only one winding, that is, the output and input share a set of coils. Definition of coupling in auto coupling is electromagnetic coupling. When autotransformer is used as a step-down transformer, a part of the turns are drawn from winding as the secondary winding. When autotransformer is used as a step-up transformer, the applied voltage is only applied to a part of the turns of winding.
    According to structure, auto transformer can be divided into variable type and constant type. The common power phase numbers are 3-phase and single-phase. In step-down starters, the transformation ratio of an autotransformer is fixed, while the transformation ratio of a contact voltage regulator is variable. Compared with general transformers of the same capacity, autotransformers have the advantages of simple structure, less materials, small size, and low price.
