Advantages 1. The toroidal transformer has a simple structure and can be flexibly designed; 2. The toroidal core is made of oriented silicon steel strip, which is a continuous closed magnetic circuit with high magnetic flux and small leakage inductance; 3. The toroidal core has low processing stress and can fully utilize the magnetic properties of the core material. Its magnetic property is better than those of other types; 4. Under the same electrical performance, the temperature rise is lower than that of other types, and has a longer service life; 5. For high-power transformers, it has the advantages of small size and high cost performance. 6.Wide application fields.
