What Is The Difference Between An Inductor And Transformer - Miracle Electronics.pptx

Although transformers and inductors look very
similar and also seem similar in construction to
a layman, they are actually two different
elements used in different applications. To help
you understand this difference, we have
explained both transformers and inductors in
detail below.
Transformers A transformer consists of two coils
of insulated wire that are wound around an iron
core. The primary coil is connected to an input
source of AC current that produces a constantly
varying magnetic field around the coil, and the
secondary coil is connected to another electric
circuit to give an output. The magnetic field
produced around the primary coil in turn produces
AC current in the secondary coil too. There is a
difference between the number of turns in both
the coils. It is this difference that determines
the voltage. The ratio of the number of turns in
the primary coil to that in the secondary coil
is called the turns ratio, and it determines the
ratio of voltages in both the coils. This means
that with one turn in the primary coil and ten
turns in the secondary coil, the voltage in
secondary coil will be 10 times that in the
primary. Similarly, ten turns in the primary
coil and one turn in the secondary coil will
result in voltage in secondary coil to be 1/10th
that in the primary. Transformers that have more
turns in the secondary coil are step-up
transformers, and those that have more turns in
primary coil are step-down transformers.

At Miracle Electronics, the leading transformer
manufacturer in India, we manufacture a wide
range of transformers including toroidal, medical
isolation, power, audio output, three phase, EI,
audio line matching, SMPS and UI. Inductors An
inductor is a passive two-terminal electrical
device that is made of an electrical wire wound
into a coil. Current when flows through the coil
will store energy temporarily in a magnetic field
in the coil. Any change in the flowing current
will create a voltage. The inductance of an
inductor is measured in Henry (H) units, which is
the ratio of the voltage to the rate of current.
These values range from 1 µH to 1 H in inductors.
The core of an inductor is magnetic and is made
of ferrite or iron that increases the magnetic
field and thus, the inductance. Inductors are
used in AC electronic equipment to block AC
current, while allowing DC current to pass. At
Miracle Electronics, we manufacture a variety of
inductors too that are ideal for any application
requiring a high DC current bias and are
well-suited for use in SMPS. With our inductors,
you can easily have the highest common mode
impedance over the widest frequency range. For
the same inductance produced by any other
solenoid, Miracle Electronics inductors require
fewer turns and are smaller in size. Our
inductors have no air gap, have a very low
electromagnetic radiation, have a safe design
with superior quality wiring, and produce
negligible noise. So, for any requirement of
inductors and transformers, you can promptly
contact us to make sure you have the best
products. We also customize products as per your
requirement, so that you receive a unique
solution to suit your needs.
