What Is Step-Down Transformer? – Definition, Formula, Working and Construction

Step Down Transformer – A device that is used to transfer electrical energy from one alternating-current circuit to another or multiple alternating-current circuits is known as a transformer. Transformers work on the principle of electromagnetic induction.

During this process of transfer, if the AC voltage is increased, it is called a Step Up Transformer, and if the voltage is decreased, it is called a Step-Down Transformer. We can say that, it converts high-voltage power to low-voltage power and also reduces the AC voltage or AC source.

In this article, we will go through the basics of Step Down Transformers. We will start our Article with what is a Step-Down Transformer, Then we will go through the construction of the Step Transformer with its working. Finally, we will conclude our Article with the Advantages, Disadvantages, and Some FAQs on the Step Down Transformer.

What is a Step-Down Transformer?

A Step-Down transformer is a type of transformer in which, when the voltage is supplied to the primary coil, it creates a magnetic flux, this changing magnetic flux induces an emf in the secondary coil by the law of induction. This induced emf is lower than the emf in the primary coil. Hence, the name Step Down transformer. It is based on the principle of mutual induction and is used to reduce the voltage from primary to secondary....

Step Down Transformer Working Principle

Since in the Step Down Transformer , output voltage is decreased which will increase the output current to maintain the balance. The primary winding is connected to AC source, when the voltage is supplied an alternating current flows through the primary coil. As the source is AC, there will be a change in magnetic flux when this changing flux passes through the secondary winding, an emf is induced in the secondary coil according to law of induction. The emf induced is directly proportional to the number of coils in the secondary coil....
