Following pictures show the size difference between classic technology E/EI cores and new toroidal technology of Traftor in a UPS applications from a UPS manufacturer.

Toroidal cores will replace more and more in the coming years the classic E and EI cores classic transformers and chokes. Traftor helps you to implement this new technology in your own solutions. Transformers range from 3 to 33 kVA and inductors from 20 to 500 kVA Read all advantages of toroidal cores solutions here. […]

Manufacturing process for E core decreases magnetic properties of the electrical steel (mechanical stresses, burrs, air gap, etc). Core loss can be higher by 20-30% than theoretical data indicated in catalogues of electrical steel core manufacturers. Mechanical stresses are much lower in manufacturing process of toroidal cores compared with EI and C shapes. Toroidal manufacturing process eliminates […]
