An Auto Transformer is a transformer with just one winding wound on a laminated core. An auto-transformer is like a two winding transformer yet contrasts in the manner the essential and optional winding are interrelated. A piece of the winding is basic to both essential and optional sides.

On load condition, a part of the load current is acquired legitimately from the gracefully and the rest of the part is gotten by transformer activity. An Autotransformer fills in as a voltage controller.  In the autotransformer, some portion of the vitality is moved by acceptance and the rest is by conduction. There are three sorts of autotransformers: step-up, step-down, and variable autotransformers which can be either step-up or step-down the voltage.

Variable autotransformers are utilized in the research facility and industry to give a wide scope of air conditioning voltages from a solitary source. The above figures show step-up and step-down autotransformers.
