I'm rather more concerned now about what kind of plating bath needs so little current that such a circuit would be reasonable. Tim |

Worst case, the capacitors will self-heal themselves to death. --- End quote --- 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. |

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. --- End quote --- 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. :) https://www.eevblog.com/forum/beginners/please-help-with-switch-selection/msg2490720/#msg2490720 |
