An AutoTransformer is a single-winding electrical transformer. The prefix "auto" refers to a single coil functioning alone, not to any form of automated device. In an auto transformer, parts of the same winding serve as the transformer's main and secondary winding sides. A regular transformer, on the other hand, contains separate primary and secondary windings with no metallic conducting channel between them.

There are at least three taps on the auto transformer winding where electrical connections are made. Because a portion of the winding does "double duty," auto transformers are frequently smaller, lighter, and less expensive than traditional dual-winding transformers. Auto transformers also have lower leakage reactance, smaller losses, lower excitation current, and higher VA rating for a given size and mass.

Construction of Auto Transformer:

It basically consists of two parts:

Conductors: The autotransformer's conductors are composed of copper. They have a poor level of resistance. The copper conductors are completely disconnected from one another. Impregnated paper, mica, and other materials are used as insulating material. Eddy current losses are also reduced by the insulation. The winding wraps itself around the center. When compared to two winding transformers, a single winding transformer requires less copper.

Core: The core is utilised to transport flux from the primary to the secondary. The core is constructed of magnetic materials such as silicon steel, CRGO steel, and others. Because it has the lowest hysteresis losses, CRGO steel is the most efficient material for core. The primary function of the core is to transport flux from one section of the winding to another.

Properties of Auto Transformer:

  • An auto transformer is a device that is both electrically and magnetically connected.
  • Power is constant in an autotransformer.
  • The total flux in an autotransformer is constant.
  • The frequency of an autotransformer is constant.
  • Voltage and current are affected by the number of revolutions.
  • A phase-shifting device is another name for an autotransformer.
  • Because autotransformers use a single winding, they have lower losses than two winding transformers.
  • When compared to two winding transformers, the autotransformer has higher efficiency.
  • Both iron and copper losses are reduced by using an autotransformer.

FAQs Related to Auto Transformer

An auto transformer is a single-winding transformer that operates on the principle of Faraday's Law of Electromagnetic Induction.

The advantages of auto transformers are:

  • Autotransformer losses are lower.
  • The auto transformer's efficiency has increased.
  • The voltage control of an auto transformer is excellent.
  • The reactance of a single winding is lesser.

  • Induction motors are started using auto transformers.
  • Voltage control is accomplished by the use of auto transformers.
  • Auto transformers are utilised in laboratories.
  • Auto transformers are utilised in a variety of industrial applications such as paper mills, industries, and so on.

No, an auto transformer is a device that is both electrically and magnetically coupled.

The auto transformer's most remarkable feature is its ability to save copper when compared to a standard two winding transformer. The weight of copper is determined by its length and cross-sectional area. The length of copper in a transformer, on the other hand, correlates to the number of turns, and the cross-sectional area corresponds to the current rating.

An autotransformer is a single-winding electrical transformer. The prefix "auto" refers to a single coil functioning alone, not to any form of automated device. There are three types of auto transformer:

  • Step-up auto transformer
  • Step-down auto transformer
  • Variable auto transformer
