HP ok so here's problem germane to thread that's totally been driving me crazy! So below is diagram of LV PSU ripple filter.
So for given values, resonant Freq of L1-C2 ckt is abt 37.5 Hz which is no problem at all! But I definitely see potential for huge problem on two _fronts_.
1) If L1 is overloaded into saturation it could lower L1's inductance enough to bring resonant freq near 120Hz which would cause HUGE (like multi-kV) drop across C2!
2) Inductive load could tune out enough of C2's capacitance to cause same problem!
So FWIW L2 would need to be lowered to ≈ 117.27μH to resonate with 15mF C2! Also it would only take ≈ 130 MICRO-Henries of load inductance to tune C2 down to ≈ 1.466mF bringing it to 120Hz resonance with 1.2mH L1! Also plz remember just getting anywhere near resonance is bad enough!

@KL7AJ when you say things like that it's like ur saying my thoughts and ideas are totally unimportant! I don't like being objectified and I bet you don't either! So I know ur not being deliberately rude and I prolly brought it all on myself with _numpty act_ but if it ever was funny it's totally run its course! So I'm asking you to plz cool it with silly remarks and contribute something of substance cuz we definitely need all the help we can get with all we're trying to do here!As for me, I am perpetually incapacitated by Aleph(0)'s unspeakable pulchritude. *sigh*
