I've been doing research on how to make E-I cores for transformers, toroids... I have iron oxide and zinc oxide handy. At the moment I am solving the chemistry for agglutination and baking. The mold and shape of the cores is no problem for me.
But here a doubt arises. How do you calculate core saturation? I understand that this by means of a proven industrial process, with exact proportions and determined purity in the raw material, can be estimated.
Has anyone made ferrite cores? how do you know when saturation occurs (heat is bad)? how often have you worked them?
In my country I do not have the possibility to buy transformers or ferrite cores, so I have to try to manufacture it myself.
I need to make some SMPS power supplies and I don't have the transformers.
Someone has some formula or way to make them? maybe it's better than how I'm doing it.
