Toroidal transformer has a perfect design, unlike other transformers. In fact, the first transformer designed by Faraday was a toroidal core transformer. Toroidal cores are made of magnetic coil transformer steel with very low loss levels and high saturation induction. This is achieved by heating the toroidal frame to a high temperature, and then cooling it according to a special program. This allows high saturation levels of up to 16,000 Gauss to be achieved. In a toroidal transformer, the magnetic flux is evenly distributed in the core and, due to the absence of intermediate metal parts and technological gaps.
Likewise, since all the winding coils are evenly distributed over the core surface, the noise caused by magnetostriction virtually disappears. Also, the toroidal transformer has the best thermal characteristics, which contributes to good cooling of the transformer. There is no need to use coolers and fans.
