AUTOTRANSFORMER Meaning and
Definition
-
An autotransformer is a type of electrical transformer that consists of a single winding that serves as both the primary and secondary winding. It is designed to transfer electrical energy from one circuit to another while maintaining the same frequency, but with a different voltage.
The autotransformer operates on the principle of mutual inductance, where a varying input voltage induces a corresponding variation in the output voltage. It consists of a common winding with three terminals: the input terminal, the output terminal, and a tap point along the winding. The tap point serves as the connection between the input and output sides of the autotransformer, allowing for voltage transformation.
Autotransformers have several advantages over conventional transformers. They are more compact and lightweight, as they require only a single winding instead of separate primary and secondary windings. This also results in higher efficiency and lower cost. Autotransformers are commonly used in applications where a different voltage level is required, such as in voltage regulation, voltage conversion, or in electrical transmission and distribution systems.
However, autotransformers also have certain limitations. Since the primary and secondary windings are not electrically isolated, a fault on one side of the winding can affect the electrical characteristics or stability of both sides. Additionally, autotransformers may not be suitable for applications requiring high levels of isolation or protection against electrical faults.

Etymology of AUTOTRANSFORMER
The word "autotransformer" is derived from two components: "auto" and "transformer".
The prefix "auto" comes from the Greek word "auto-" meaning "self" or "same". In the context of the autotransformer, "auto" refers to the self-adjusting nature of the device, as it has a single coil that acts both as a primary and secondary winding.
The term "transformer" has Latin roots, with "trans" meaning "across" or "beyond" and "former" referring to "to form" or "to shape". Therefore, a transformer is a device that enables the transformation or transfer of electrical energy between two or more circuits through electromagnetic induction.
Combining these components, "autotransformer" signifies a type of transformer where a single winding is used to transfer electrical energy between different parts of a circuit, typically with a different voltage or current.
