The use of amorphous, highly permeable, soft magnetic alloys with a low coercive force, and low magnetic reversal losses, in high-frequency transformer cores can improve their characteristics. This work comparatively analyzes the characteristics of a toroidal transformer using a 5BDSR microcrystalline alloy core with the parameters of a TPI-9 industrially-produced transformer using a manganese-zinc ferrite core.
