Are Toroidal Transformers Better?

Are Toroidal Transformers Better?

Toroidal transformers are named after their torus shape, meaning they have a donut-like form. These transformers have a toroidal-shaped magnetic core with coiled primary and secondary wires. Their design can provide increased flexibility and efficiency.

So, are these transformers better? Why is that the case?

Yes, toroidal transformers are considered better than other transformers for devices rated up to 15 kVA. Toroidal transformers benefit use on equipment in the following applications, among others:

  • Renewable energy
  • Audio
  • Medical
  • Industrial
  • Manufacturing

Here, we’ll investigate why toroidal transformers are better than standard transformers.

Why Toroidal Transformers Are Better

Compared to a standard transformer, a toroidal transformer’s torus shape efficiently decreases stray losses and allows for shorter windings. They also emit less audible vibration and are compact.

Toroidal Transformers Have Higher Efficiency Ratings

Toroidal transformers have greater efficiency, with a 90 to 97 percent efficiency rating.

At Amgis, our standard toroidal transformers are at least 95 percent efficient.

What do standard laminated transformers offer? They typically offer lower than a 90 percent efficiency rating.

Fewer Stray Losses Benefit Renewable Energy

Heightened efficiency, combined with comparably fewer stray losses than traditional transformers, makes toroidal transformers a better option for renewable energy applications.

Toroidal Reliability & Efficiency Meet Industrial & Manufacturing Needs

Industry professionals needing a transformer for industrial and manufacturing applications benefit from toroidal transformers’ heightened efficiency, reliability, and compactness.

Quieter Than Traditional Transformers

Audio equipment such as a power amplifier needs as-quiet-as-possible audio power transformer options to produce the best sound. Toroidal transformers offer fewer vibrations and humming noises than traditional transformers, providing better quality sound for audio applications.

Their smaller size compared to standard laminated transformers also facilitates mounting and meets possible size restrictions. For example, EI transformers typically need four mounting points, whereas toroidal transformers only need one mounting point with one bolt.

Toroidal Transformers Can Meet Medical-grade Requirements

Medical equipment must meet precise requirements for an array of life-saving procedures. Our Toroid Medical Grade Isolation Transformer series, in particular, is fine-tuned to meet strict safety and reliability standards. Amgis medical-grade toroidal transformers last through the life of the medical equipment.

We hold a CB Test Certificate to IEC 60601-1 3rd edition for this line. This certificate means Amgis’s medical-grade toroidal transformers are certified for use in medical products intended for use in Europe.
