Analog power electronics help needed!
« on: July 09, 2010, 10:45:31 AM »
Normally I don't like to cross post a bunch of stuff, but I've run into an interesting electronics problem and due to where I originally posted it I don't think I've reached the best audience.

Quick back story, I've made a "DCC in a Box" setup, documented on my blog ( and there has been some discussion on this site in this thread:,21209.0.html

I've found a problem where Digitrax Boosters and the electronically switched power strip I am using interact badly.  Documented in this blog post:

An in depth discussion of my proposed solution is taking place over on, for whatever reason, the thread just took hold there:

What we really need is another brain or two with knowledge of MOSFETs and analog power circuits to help verify the design of the solution.  If that is you, I would much appreciate if you could comment, on the blog, on the thread, or even here.  Again, apologies for cross posting, but I think many of the folks I need to reach don't read the DCC forums (they are, after all analog electronics experts [:D]).

ok, i think i follow - the inrush current on the Digitrax brain unit is shutting down the switched outlet power panel.  why are you using a switched outlet panel?  just use a buss and be done with it - it seems you are creating more work.  if you are worried about over current that's what fuses are for...

How long will it be before they show us how to add DCC to a tree?
