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...

Comparing Classic EI, EE, C foil inductors, Flat wire toroidal inductors are hot in the market, here let’s discuss why people prefer flat wire, rather than common toroidal wire: Round Wire Limitations Frequencies >20KHz Round wire take best efficiency in frequencies up to 20KHz. In higher frequencies, skin effect (with electrons travelling mainly on the surface area of the conductor instead of ...

The four-phase common mode choke is a four-terminal device, which founded by a nanocrystalline magnetic toroidal core as a common mode interference suppression device, four sets same size, same turns numbers coils wound symmetrically. When the common mode current flows, the magnetic flux in the magnetic ring superimposes each other, resulting in a considerable inductance, which has a suppressing e...
