What is a toroidal transformer

Toroidal transformers are a large type of electronic transformers, which have been widely used in household appliances and other electronic equipment with higher technical requirements. Its main purpose is to be used as power transformers and isolation transformers. Toroidal transformers have a complete series abroad, which are widely used in computers, medical equipment, telecommunications, instruments and lighting. China 0010010 #39;s toroidal transformers have grown from scratch in the past ten years. So far, they have formed a considerable production scale. In addition to meeting domestic demand, they have also exported a lot. Domestically, it is mainly used for audio equipment and automatic control equipment of home appliances and quartz lamp lighting.

Toroidal transformer characteristics
High electrical efficiency The core has no air gap and the stacking factor can be as high as 95%.
Vibration noise is small. The core does not have an air gap to reduce the vibration noise of the core. The windings evenly and tightly wrap the ring core, effectively reducing the 0010010 quot;buzzing 0010010 quot; caused by magnetostriction.
Low operating temperature Because the iron loss can be 1.1W / kg, the iron loss is very small, the temperature rise of the core is low, and the windings have good heat dissipation on the lower temperature core, so the transformer temperature rise is low.
Easy to install the toroidal transformer has only one mounting screw in the center, which is particularly easy to quickly install and disassemble in electronic equipment.
