RE: converting to critical L input filters or not ...

There is an advantage in ripple reduction in 2 LC section critical L input filters.

But that is not a huge win because the ripple is reduced by the OPT turns ratio, so the flywheel also performs well enough in that regard.

The 3 stage LC flywheel filter perform better in PSUD2 step current tests in terms of settling time and regulation at point of use.

If there are any marked differences that would appear in the baseband Hz's that would effect THD, THD+N, IMD or beat note distortion or any other operation parameter of note, I have not gone that far in testing or comparing critical vs. sub-critical L filters to make any statements pro or con.

As of now, I will stay with the 3 stage flywheel.

Thanks for the comments.
