Working principle of toroidal transformer

1 The iron core with high electrical efficiency has no air gap, the stacking coefficient can be as high as 95%, the magnetic permeability of the iron core can be as high as 1.5~ 1.8T (laminated iron core can only be 1.2~ 1.4T), the electrical efficiency can be as high as 95%, and there is no-load current.

2, the overall size is small, and the weight of the ring transformer can be reduced by half compared with that of the laminated transformer. As long as the cross-sectional areas of the magnetic cores are kept equal, it is easy for the toroidal transformer to change the length-width-height ratio of the magnetic cores, and the required overall size can be designed.

3. The toroidal transformer core with less magnetic interference has no air gap, and the windings are evenly wound on the toroidal transformer core, which leads to less magnetic leakage and electromagnetic radiation, and can be used for high-sensitivity electronic equipment, such as low-level amplifiers and medical equipment, without additional shielding.

4, the vibration noise is small, and the iron core has no air gap to reduce the iron core.
