Why Are Toroidal Transformers A Better Choice? – Miracle Electronics

Like every transformer type, a toroidal
transformer is designed to change the AC
current, without the need for any type of
movement or action, on the part of the
component. But, what makes it different is that
its doughnut shaped core is made of cold-rolled
silicon steel, which boosts the performance of
the core, as compared to any other traditional
laminated core.
The core is wrapped with a coil that generates
magnetic field lines, which are completely
coincident with the magnetic circuit of the core.
This results in a reduced excitation energy and
core loss. A toroidal transformer thus benefits
the application by offering high electrical
efficiency and less magnetic interference, packed
in a small size, which also makes it absolutely
light in weight. Distinguishing the outcomes
produced by a toroidal transformer By using an
efficient toroidal transformer, large amounts of
energy can be saved. Let us take an example. You
can take two different types of transformers for
the same application for instance, one being an
EI-core transformer 2 x 24V 50 VA, and the
second being a toroidal transformer 2 x 9V 50 VA.
Loading both these transformers with several
load resistors, and the loading power ranging
from 5 to 40

• Watts, the energy losses can be measured to find
  the remarkable difference between the two
  outcomes. The difference between the input and
  output powers is the energy loss that is
  converted into heat within the transformer.
  Moreover, dividing the output power by the input
  power can also bring to you the transformers
  efficiency. Calculating with different numbers
  of load resistors, youll be able to clearly see
  the significant differences in the outcomes. The
  toroidal transformer will result in much less
  losses than an EI transformer.
• Where can you use a toroidal transformer?
• Toroidal transformers are used widely in home
  appliances and other electronic equipment with
  high technical requirements, such as computers,
  lighting, telecommunications, audio equipment,
  medical equipment, and automatic control
  equipment. You can choose to use the same for
  your equipment too. And, to bring about even
  better results, you can opt for a customized
  toroidal transformer, manufactured by
  professional and expert toroidal transformer
  manufacturers in India.
• Designing a customized toroidal transformer
• Before designing a customized toroidal
  transformer, there are certain parameters that
  need to be considered some of them being
• The industry With every industry having
  different requirements, the industry and
  equipment in which the toroidal transformer needs
  to be used should be thoroughly considered and
  understood.
• Input voltage Generally, the toroidal
  transformer is designed according to 220V, but
  it can also be customized as per any special
  requirements regarding the input voltage.
• Output voltage and current Whether the toroidal
  transformer is single or multi-wound, the output
  voltage and current of each winding needs to be
  considered well.
• Output power The wattage obtained by
  multiplying the output voltage and the output
  current also needs to be contemplated.

• The installation method The kind of
  installation method needs to be carefully
  decided upon, such as bracket installing, middle
  hole potting, full potting, etc.
• Any other special requirements Any other
  special requirements such as the lead length, or
  whether the lead needs to be added with a
  terminal plug, and other such considerations,
  need to be reflected upon.
• Whether standard or customized, whatever your
  choice may be, Miracle Electronics are the
  toroidal transformer manufacturers in India you
  can rely upon to satisfy all your requirements!
