The toroidal transformer is a large type of electronic transformer, has been widely used in home appliances and other electronic equipment with high technical requirements, its main use is as a power transformer and isolation transformer. Toroidal transformer in foreign countries has a complete series, widely used in computers, medical equipment, telecommunications, instruments and lighting and other aspects. Our country in the past ten years the toroidal transformer from scratch, so far has formed a considerable production scale, in addition to meet the domestic demand, but also a large number of exports. Domestic mainly used for home appliances, audio equipment and automatic control equipment and quartz lamp lighting and so on. Toroidal transformer due to excellent performance-price ratio, good output characteristics and anti-interference ability, thus it is a competitive electronic transformer.
Electrical efficiency of high speed core without air gap, stacking factor can be as high as 95% or more.
Smaller vibration noise core without air gap can reduce the noise of core induced vibration, winding uniform tightly wrapped toroidal core, effectively reducing the magnetostriction caused by the "hum" sound. Low operating temperature due to iron loss can do 1.1W/kg, iron loss is very small, low temperature rise of the core, the windings in the lower temperature of the core on the heat dissipation situation is good, so the transformer temperature rise is low.
Easy to install toroidal transformers have only one mounting screw in the center, which makes it especially easy to quickly install and remove in electronic equipment.
