The autotransformer is a transformer with only one winding, which is used as a lifting voltage. Compared with the ordinary transformer, the autotransformer of the same capacity is not only smaller in size but also more efficient, especially when the ratio of variation is close to 1, it is especially economical.

Therefore, this advantage is more and more prominent in high-power transmission transformers with similar voltage. Therefore, autotransformer is widely used in many fields, such as large volume, low loss, and low cost, especially in the fields of import and export equipment power supply, high power motor startup, and so on.
