Hi,
I'm working with a solenoid (part of yet another model train setup!) which will be tripped by a relay...the switching part of the circuit is fine; now it's time to deal w/another issue.
The train owner (my father in law, lol) is trying to come up with a scheme to avoid the very momentary loss of voltage when the solenoid energizes (inrush). My thought is to build a bank of capacitors across the PS back where the transformer is...they would charge up on power-on and provide a 'reserve' for the infrequent times he switches tracks with this solenoid. The amount of time involved is less than 10ths of a second.
So what I am looking at is a reservoir...I'm not familiar with how this is done, however....would there be required resistances? Drawbacks to doing this (I'd put in a bleeder network, of course). He's not set on whether to run the solenoids from AC or DC....seems to me, DC would be better if we're adding caps....
Can this be done, or should he maybe consider power JUST those solenoids (3, I think) from another power supply??
Thanks!
