Last night I was runnin' my "new" Fleischmann switcher around and round the test loop. It runs pretty smooth. It's got a coil (choke) in series with the motor. What would the effect be. Oppses AC or changes in DC. So, what's the effect? Smoother starts and stops? Sort of electronic flywheel? I don't think this particular coil is big enought o have a significant effect. It responded well to pulsing, and I would expect a coil to remove the pulses or smooth them out. How about a big cap between the "rails" or across, parallel with motor? It should atleast give a little coasting action. I might play with some big caps. I'm going to build a high freq pulse DC supply and I might put an RC on the control circuit so as you cut back quickly, the pulses get narrower slowly. Any thots? Is anyone else interested in making their own hi end analog supply?
