The toroidal transformer is a special high-frequency transformer

 

Toroidal transformer is a special high-frequency transformer, also known as torque inductor. Toroidal transformer has the characteristics of simple structure, sophisticated manufacturing process, small size, light weight, energy saving, etc., and is widely used in the fields of electricity, telecommunications, medical treatment, instrumentation, etc. 1. Definition of Toroidal Transformer Toroidal transformer is a special high-frequency transformer composed of iron core and winding. The shape of the iron core is toroidal, and the number of turns of the winding along one circle of the iron core is the same, forming a unit turn. The input coil and the output coil are wound on the iron core in the same direction and number of turns, thus forming the output and input ends of the toroidal transformer.

Toroidal transformer is a major type of electronic transformer, which has been widely used in household appliances and other electronic equipment with high technical requirements. Its main use is as a power transformer and isolation transformer. There are complete series of toroidal transformers abroad, which are widely used in computers, medical equipment, telecommunications, instruments and lighting. In the past ten years, toroidal transformers have been developed from scratch in my country, and have formed a considerable production scale so far. In addition to meeting domestic demand, they are also exported in large quantities. They are mainly used in household appliances, audio equipment, automatic control equipment, quartz lamp lighting, etc.
