What Is an Auto Transformer?

An auto transformer is a type of electrical transformer that shares a common winding between the input and output circuits. Depending on the requirement, it can either increase or decrease voltage levels while maintaining efficient power transfer. Because a portion of the electrical energy is transferred directly through the winding, the transformer experiences lower losses compared to traditional transformer designs. This makes it a preferred choice in situations where electrical isolation is not a primary requirement. Auto transformers are commonly used in industrial facilities, manufacturing plants, power distribution systems, automation applications, and testing environments where reliable voltage control is essential.
