Typical Winding Diagram

autotransformer winding

An autotransformer has only one winding and the required voltage is tapped off at the required turns. Both the input and output shared a common neutral. An autotransformer does not provide galvanic isolation and it is designed to simply step down or step up the voltage. Sharing the same winding significantly reduce the size and cost of the transformer.
