what is a toroidal power transformer?

A toroidal power transformer is a type of transformer characterized by its doughnut-shaped core, made from a continuous ring of magnetic material. This design minimizes electromagnetic interference and improves efficiency by reducing stray magnetic fields. Toroidal transformers are compact, lightweight, and exhibit lower losses compared to traditional laminated transformers. They are commonly used in audio equipment, power supplies, and various electronic applications due to their superior performance and reduced size.
