Slowest ferrite material
Which is the slowest ferrite material? I mean I'm trying to get an estimate of how much worse ferrite may be than the common silicon steel found in most mains powered equipment supplies.
Ferrite materials are not substitute for silicon steel most of the application.
Ferrite materials having less flux density 0.4T steel having 2T so you have to increase more turns in ferrite core. especially 50 /60Hz application practically not worth.
But silicon steel does not support high frequencies, there are many losses in that situation and my doubt is what will happen with ferrite, I don't know if it will be the same or worse
Ferrites are used in highly frecuency range because of its high electrical resistivity and low eddy current losses when they work at wide frecuency range. They are not suitable for low frecuency operations. If you want to use ferrite core at 50Hz you will need a 50 times larger transformer than using one equivalent made of silicon steel with laminations to reduce eddy looses.
It is not worth it.
