The best way in my opinion is crushing the ferite and turn it on to powder and glue them back with an insulation matrial ..this technique can reduce the core permibilty and pruduce softer saturation curves and also resudes the conductivity of the core too
Nice description but another limitation of a transformer is the conductivity of the core most ferrit core acting like a semiconductor and as you apply a higher voltgaes to the transformer the core becoms more conductive
Is it a better to decrease the inductance or increase it?
Please confirm if I understood correct : the result of using the air gap is to decrease the inductance and allow the increase of frequency without going to saturation
I think there is no privilege to increase or decrease, it depends on what you need. However, the limit of inductance value is a problem when we add the gap but this comes to the advantage of accumulating the energy within the gap and get more stable inductance value. This also allow to reach more current without saturation. The benefit of this is that more current at same voltage allows higher power transfer if you use a transformer.
