Q1. What’s the advantage of CRGO core toroidal transformer? The core of toroidal transformer is rolled by high-quality CRGO sheets (thickness <0.35mm), its performance is superior to laminated cores. The coils of toroidal transformer were wound on the core evenly, the direction of magnetic field lines generated by the coils almost completely coincides with the magnetic circuit of the core. Comp...
