the Math behind LC filter output voltage

For a rectified sine function, the Fourier series has an a_0 term. No sine function of any sort along with it. This is the DC component. Its magnitude is 4/Pi times the voltage input, which of course is root2*RMS voltage...

Once you've attacked this with a slide rule, that a_0 turns out to be ~.9095 times the rms input voltage.

So, as the choke gets better and better( increasing Hy), the output gets the remaining AC voltage removed and we are left with the DC term... :) Now this ignores the multi-stage resonant effects Medwin discovered, and then dismissed as worthless once Henry Pasternack delivered an analysis of his sim work on the Flywheel...and the parasitic capacitance winding a real choke will have.
