transients in capacitor droppers
T3sl4co1l:
I'm rather more concerned now about what kind of plating bath needs so little current that such a circuit would be reasonable.

But for loads involving semis whats the ideal inductor for this?
Gyro:
No simple answer, it would need to be very lossy to prevent ringing and peaking on different transient edge rates (or made lossy using external components). The advantage of a resistor is that it is more or less broadband.

Current rises with more capacity between mains and rectifiers.

EDIT: This is becoming rather more like Frankenstein's laboratory - I think this is the first time that you have revealed that it's to be used for electroplating.

Yes, I hope LaserTazerPhaser realizes that the grounds on the schem. are always at live mains voltages.
It reminds me of the cap dropper battery rejuvenator. :)
