What Features Of Toroids Provide For An Efficient Operation?

    Toroidal transformers are round/doughnut shaped transformers with wires around the core made of ferromagnetic materials like laminated iron, iron powder or ferrite. The core cross-section can be circular, square or rectangular, out of which the circular one is most expensive. Toroidal transformers have complete magnetic field cancellation outside their core, which results in lesser leakage inductance and less EMI when compared to other types of transformers of the same power rating.

Toroidal Transformers

Toroidal transformers are used in a wide variety of applications. In fact, any electronic transformer application that can accommodate the shape of a toroid can use it. However, although these transformers are usable, they are not always practical for certain applications. The most common applications you can see toroids being used in include medical isolation equipment, audio and audio-visual equipment, security systems, telecommunication systems, automotive electronics, power distribution equipment, industrial control equipment, LED lighting's, and renewable energy inverter systems. If these are any of the applications you are looking to use a transformer in, make your purchase from Miracle Electronics to get the best-in-class and most superior kind of toroidaltransformer in India, made of superior high quality materials.

Characteristics of Toroidal Transformers

·        Toroidal transformers have cores made of good quality cold-rolled material, rolled together, to make the core superior than any other laminated core. The coils are uniformly wound around the core with the direction of magnetic lines almost completely overlapping with the core magnetic circuit. Because of the symmetrical toroidal core shape, only a small amount of magnetic flux can escape. This is how core losses are reduced by almost 25%, while other transformer types have core losses up to 50% of the total transformer losses!

·        Because of the small core loss and being easy to change in terms of length, width and height, toroidal transformers are smaller in size and light in weight (weight being almost half of other transformers).

·        The no air gap of the core results in high electric power efficiency of up to 95%!

·        The no air gap results in less magnetic loss and less electromagnetic radiation, thus being easily used in highly sensitive electronic devices without additional shielding.

·        The construction of toroidal transformers provides transformer operations without acoustic noise, while vibrations of iron lamination's can produce acoustic noise. Therefore, the no air gap also reduces vibration noise to a great extent.

·        Less iron loss leads to low core rising temperature and low operating temperature. And, winding on the core at low temperature heat makes for good heat dissipation.

·        With only a single screw mounting in the center, toroidal transformers are way too easy to install or dismantle.

However, with all these benefits comes one big disadvantage of toroidal transformers; and that is the price they come at. Their complex construction and wire winding makes them very expensive to manufacture, which is why the price of toroidal transformers is higher than other types of transformers. But, with the benefits they come with, the price should not be a matter of concern. After investing in a good quality toroidal transformer, you will definitely realize that the long-lasting results are worth it.
