Toroidal transformers are the high performers among transformers. They offer the smallest size (by volume and weight), less leakage inductance, and lower electromagnetic interference (EMI). Their windings cool better because of the proportionally larger surface area. A 360 degree wound toroidal transformer has a high degree of symmetry. (read more)
