toroidal transformer definition

A toroidal transformer is a type of electrical transformer characterized by its toroidal (doughnut-shaped) core. It consists of a coil of wire wound tightly around a circular or toroidal core made of ferromagnetic material, such as iron or ferrite. The primary winding of the transformer receives alternating current (AC) input, inducing a magnetic field in the core. This magnetic field, in turn, induces a voltage in the secondary winding, allowing for the transformation of electrical energy from one voltage level to another.

Toroidal transformers are known for their compact and efficient design, which minimizes magnetic flux leakage and reduces core losses. They offer several advantages over traditional laminated transformers, including higher efficiency, lower electromagnetic interference (EMI), reduced size and weight, and quieter operation. Toroidal transformers find applications in various industries, including audio equipment, medical devices, industrial automation, telecommunications, and renewable energy systems, where space-saving and efficient power conversion are essential.
