In regulator circuits, inductor is connected in series with rectifier circuits for blocking AC.
Inductor is allows Direct current(low frequency) and blocks alternating current(AC) this is because of inductive reactance.
Inductive reactance is XL=2pif.
If frequency f is high,inductive reactance also high so it blocks high frequency signal.it means high frequency alternating current(AC) is blocked by inductor.
similarly,if frequency f is low,inductive reactance is low so it allows low frequency signal.it means low frequency direct current(DC) is allowed by inductor.
