A toroidal transformer is a type of electrical transformer constructed with a torus or donut-shaped core, which is widely used in various applications such as isolation equipment for the medical industry, industrial control equipment, and automotive electronics. It consists of a primary and secondary winding wrapped around a ferromagnetic core, typically made of materials like iron powder or silicon steel. The toroidal shape of the core allows for efficient containment of the magnetic field, reducing leakage flux and electromagnetic interference (EMI), which results in higher efficiency and lower noise levels.
