hi everyone.
i got a question. i was doing this circuit, in which i want to make a voltage source, connected to the line and that returns approximately 30V, but the problem is that it has a lot of ripple, I put the inductor to lower the ripple and fix it a bit, the problem is that I do not have inductors with values so large, otherwise the ripple would be completely reduced with an inductor of for example 1h, but i can't get an electronic component of such value.
.i can't get an electronic component of such apacitor value either, so those are the values I can't change. the 60ohm resistor I can't change it either because it represent an equivalent circuit connected to this source.(the voltage of the line is 220*sqrt(2) here, and 50hz) (the for diodes are Schottky type, )
What else can I do to decrease the ripple?
here is the .asc (voltagesource.asc (below))and a .png of the circuit
Another thing I try is adding a zener diode to it as seen in the picture, and that solves the problem, but it gives me gigantic currents in the inductor and all the diodes. currents much greater than their maximum values (the TFZ12B is a zener diode)

thanks!
