Performance Characteristics of Transverse Magnetic Cores

Iron-based nanocrystalline cores heat-treated by transverse magnetization have a high saturation magnetic induction of 1.25 T (relative to ferrite), high permeability u=30,000 - 100,000 (relative to ferrite u=10,000 or less), low remanent magnetization Br values, typically a rectangular ratio of Br/Bm<0.3 (relative to iron nanocrystalline cores without transverse magnetization >0.6), and low iron loss (relative to ferrite, iron nanocrystalline cores without transverse magnetization, conventional silicon steel sheet materials). cores Br/Bm>0.6), low iron loss (relative to ferrite, iron based nanocrystalline cores without transverse magnetization heat treatment, and conventional silicon steel sheet materials). Iron-based nanocrystals with transverse magnetization heat treatment can be used as transformers in single-ended topology circuits because of the high saturation magnetic induction Bs and low remanent magnetization Br, which gives a large ΔB. When used in push-pull, half-bridge and full-bridge circuits, the low Br value avoids the risk of saturation of the transformer due to DC bias.
