snubbers

<< < (2/2)

G8B4Life:
The OP actually encountered it just shy of  2 years ago and updated the progress a few days ago. Verily a long time between updates.

Does go to show how big the spikes with ringing can get; surprised they didn't actually blow any decoders.

Since the use of snubbers work on DC layouts, are they necessary or useful on Railpro layouts?

G8B4Life:
I don't think the usual DCC snubber (resistor and capacitor) works for DC but I'm no electronics expert. Alan gives a very good writeup of the problem in his blog posts linked to in one of his posts above. Now Alan has some very long buses but found he did not actually need the negate the ringing. I forget why now and it's probably due to what else he connected to the buses that others may not do so it's a your mileage may vary situation but I'm pretty sure that unless your buses are super long you shouldn't need any dampening.
