Transformer

A transformer is a magnetic component or an electric component which transforms electrical a.c. power from one circuit to another circuit without changing the frequency. It works on principle of mutual inductance. Transformers are capable to of either increasing or decreasing the voltage and current levels of their supply, without modifying its frequency, or the amount of electrical power being transferred from one winding to another via the magnetic circuit.

Construction

It consists of two highly inductive coils which are electrically separated, but magnetically linked through an iron core of low reluctance. The two coils possess high mutual inductance.

 

Types of transformers

The various types of transformers are as given below.
