What You Need to Know About Toroidal Transformers in Battery Chargers？
A toroidal transformer is a type of electrical transformer characterized by its doughnut-shaped (ring-shaped) magnetic core, typically made from ferromagnetic materials such as laminated iron, iron powder, or ferrite. The primary and secondary coils are wound around this circular core, allowing the transformer to transfer electrical energy from one circuit to another through electromagnetic induction.
