Output filter inductance is used to filter the AC ripple after rectification.If a larger direct current flow through the inductor, the magnetic permeability and inductance change the smaller the better under the condition of DC bias magnetic. That means within a certain range of DC magnetization ,the inductor has to have a constant magnetic conductivity characteristics ( or constant inductance characteristics).In other words, the magnetic permeability ( or inductance value) can't be less than 50% of its initial value. Nowadays, amorphous magnetic cores have been widely used in output filter inductor.
