Toroidal Power Transformers

The closed ring shape of a toroidal transformer eliminates air gaps inherent in the construction of an E-I core. The primary and secondary coils are often wound concentrically to cover the entire surface of the core, which provides screening to minimize the core’s magnetic field from generating electromagnetic interference.

APITech winds their own silicon steel cores to ensure that the grain boundaries are optimally aligned, improving the transformer's efficiency by reducing the core’s reluctance.
