Toroidal transformer is a type of transformer and is widely used in home appliances and other electronic equipment with high technical requirements as a power transformer and an isolation transformer. Due to its excellent performance and good price ratio, the toroidal transformer has good output characteristics and anti-interference ability. To be specific, toroidal transformers are widely used in computers, medical equipment, telecommunications, instruments and lighting.

Toroidal Transformer Features

The toroidal transformer core is made of high-quality cold-rolled silicon steel sheets that reach generally below 0.35mm in thickness and are seamlessly rolled, which makes its core performance better than the traditional laminated core. The coil of the toroidal transformer is evenly wound on the iron core and the direction of the magnetic field lines generated by the coil almost completely coincides with the magnetic circuit of the iron core. Compared with the laminated iron core, the excitation energy and iron core loss of the toroidal transformer core will be reduced by 25%.

Toroidal Transformer Advantages

1. High electrical efficiency, the toroidal transformer core has no air gap, the stacking coefficient can be as high as 95% or more, the magnetic permeability of the core is 1.5~1.8T (the laminated core can only reach 1.2T~1.4T) and the electrical efficiency is as high as more than 95%. The carrying current is only 10% of the laminated type.

2. Small size and light weight. Toroidal transformers have half weight of laminated transformers. As long as the cross-sectional area of ​​the core is kept equal, the ratio of the length, width and height of the core of toroidal transformer can be designed to meet customers' requirements.

3. Less magnetic interference. The core of the toroidal transformer has no gas gap and the windings are evenly wound on the toroidal core. As a result, this structure leads to small magnetic flux leakage and small electromagnetic radiation. It can be used in high-sensitivity electronic equipment without additional shielding, such as low-level amplifiers and medical equipment.

4. Small vibration noise. The iron core has no air gap, and the windings evenly and tightly wrap the annular iron core, which can reduce the noise of the induced vibration of the iron core.

5. Low operating temperature. Since the iron loss can be 1.1W/kg, the iron loss is very small, the temperature rise of the iron core is low and the winding is well dissipated on the iron core with a lower temperature, so the temperature rise of the transformer is low.

6. Easy to install. The toroidal transformer has only one mounting screw in the center, which is particularly easy to quickly install and remove in electronic equipment.
