Types of Transformer: An Article About How Transformers Differ in Construction and Design


Among all the innovations that the world of engineering has experienced and given birth to, a transformer is the extraordinary and one of the most vital innovations. It is an electromagnetic static device that is used to transfer electric power in one circuit to another one with changing in voltage level but no fluctuation in frequency. It is called static because there is no rotating or moving components in its construction. Transformers follow the rules of electromagnetism introduced by Michael Faraday. In the following sections, we will discuss different types of transformers. Although transformers differ in their designs and construction, they all adhere to almost the same working principle. 

Types of Transformers based on Voltage Level

In terms of construction, a Transformer can have multiple types. Although there is no electrical connection from one side to another side of a transformer, the two completely and electrically autonomous coils can direct the electricity by the electromagnetic transition. Transformers can be conducted in a way that they can change the voltage level from the primary side to the secondary side. Contingent on the voltage level, transformers are categorized into three types. In the following sections, we are going to elaborate on these three types in detail.

  1. Step-Down Transformer

Both Electronics and Electrical domains enjoy the benefits of step-down transformers. What a step-down transformer does is to change the primary voltage level to a lower one and delivers it to the secondary output. The ratio of primary and secondary windings make it happen. In this type of transformers, the number of coil windings across the primary side is higher than the secondary side. so, the overall ratio for winding of these two sides is always more than 1.

  1. Step-Up Transformer

As the name implies, what a step-up transformer does is exactly the opposite of what a step-down transformer does. A step-up transformer is a type of transformer whose job is to increase the low voltage of the primary coil to a high voltage in the secondary coil. Again, the ratio of primary and secondary windings makes the change or conversion of voltage level. In the working principle of a step-up transformer, the overall ratio of the primary and the Secondary winding is less than one. It means that the number of turns of coils in the secondary winding is higher than the primary winding.

  1. Air-Core transformer

    In the air-core transformer, we do not see any physical magnetic core as the core material. The flux linkage of the air-core transformer entirely happens by using the air.

    In this type of transformers, the primary coil is fed with alternating current producing an electromagnetic field around it and the secondary coil is put inside the magnetic field. Based on the Faraday law of induction, the secondary coil is induced with a magnetic field that is used to power the load.However, in comparison to a physical core material such as iron and ferrite used in transformers, air-core transformers create low mutual inductance.

  2. Isolation Transformer

The isolation transformer does not change the level of voltage. As the number of turns in primary and secondary windings of isolation transformers is the same, the primary and the secondary voltage of an isolation transformer is always the same. the reason is that the primary and the secondary winding ratio is always equal to 1.

Transformer Types based on Core material

All the transformers transfer energy by carrying electromagnetic flux through a core material. The density of flux completely depends on the core materials. So, Different core materials lead to different flux density. Based on the core materials, we can categorize transformers into three main types. These types are used in the power and electronics domain.

Iron Core Transformers 

Ferrite Core Transformers

Air-Core transformer

Other Type of Transformers

There are some other types of transformers that we preferred not to put them in a determined category. In the following section, you will get acquainted with three more kinds of transformers. Stay with us till the end.

  1. Single-Phase Transformer

  1. Three-Phase transformer

  1. Power Transformer

Conclusion

Transformers are produced in a wide range to meet different needs. Some Transformers  are huge and typically are found at a generating station or power plants, while some are small enough to be used with charging cradles. Whatever shape or size they may have, their purpose is the same: transferring the electrical power from one to another type. For source info, click here!
