A toroidal transformer is a type of electrical transformer with a donut-shaped core made from ferromagnetic materials like laminated iron, iron powder, or ferrite. This unique shape provides several advantages over traditional rectangular or square-shaped transformers.

The primary and secondary windings of a toroidal transformer are wrapped around the core and separated by insulation. This design minimizes magnetic flux leakage, enhancing efficiency and reducing electromagnetic interference (EMI). Due to its symmetry, the toroidal core allows for efficient containment of the magnetic field, resulting in lower core losses and higher efficiency.

Toroidal transformers are known for their compact size, low weight, and high power density. They are widely used in various applications, including power supplies, inverters, amplifiers, medical equipment, and audio systems. These transformers can be customized to meet specific requirements, such as different voltage levels and power ratings.

Toroidal transformers offer several benefits, including high efficiency, low noise, low signal distortion, and minimal electromagnetic interference. Their compact and lightweight design makes them suitable for a wide range of electronic applications.
