Abstract:
Transformer is an electro mechanical
device which transfers electrical energy
from one circuit to another by means
of changing magnetic field, without
changing the frequency. Different types
of transformers are used for different
electronic applications. Advancement in
the field of electronics has influenced
change of design and use of new type
of core materials. The transformer
depending on application can be
classified into power transformer,
current transformer, constant voltage
transformer, impedance matching
transformer, driver transformer, audio
output transformer, ignition transformer,
pulse transformer, fly back transformer,
ferrite core transformer, IF transformer
etc.
