The advancement in technology of high frequency inverters has culminated in several advantages. Some of those incl ude the physical size of the inverter being smaller, a lighter weight of the individual unit and a higher efficiency of the working unit. The main transformer is heart of a power inverter, with a working frequency up to more than 20kHz. The transformer, in the past, was made from a core of silicon steel, but that can no longer meet the technical requirements of today's industrial and technological world. Though Ferrite has a lower loss at high frequencies, but it has a lower saturation flux density and not much reduction in volume and weight, further more, the ferrite metals have lower curie temperatures and less thermal stability. In contrast, Fe-based nano-crystalline structure material has much better magnetic properties. This material integrates the advantages of silicon steel, NiFeNb alloy and ferrite resulting in high flux density, high permeability, low currency loss, and good thermal stability, making it the best material for manufacturing power inverter cores.
Jun-21-20
 
Toroids have the best possible shape from the magnetic point of view. The flux path is completely closed so the capabilities of the ferrite are fully exploited. Especially for high permeability ferrites
the effect of even a minor airgap in the magnetic circuit
can spoil up to 50% of the effective permeability. A further
advantage is the very low leakage fi eld which makes it a
suitable shape for power and pulse transformers.
Ring cores are mainly used for pulse- and wide band transformers and interference suppression coils but also in
special power supplies.

Due to the high saturation fl ux density
of iron powder (950...1600 mT) these
ring cores are very suitable for output
chokes carrying high DC currents.
Another application is found in lamp
dimmers as ballast choke.
The cores are made of electrolytic iron
powder, mixed with a small amount of
resin for insulation. They are coated
with polyamide 11 (thickness 0.1 - 0.3
mm). The isolation voltage between
