The application is for an electric model train (HO) which operates on 0V - 16V DC power supply.
Locomotives often suffer from momentary power outages when crossing points, turnouts etc.
Some are equipped with a mechanical flywheel which keeps momentum for an inch or two which may be enough.
Many low end locomotives does not have any "keep alive" equipment and requires a push when they get stuck.
There are available off-the-shelf solutions but they are not affordable.
Would a capacitor serve a purpose?
Would it not limit the current to the DC motor while charging? PSU is capable of 1000ma @ 12V.
How to size it? The DC motor typically draws 250ma @ 12V.
What will happen when a power outage occurs? It will keep the motor running and then what?
I know, that I know very little about electronic!
Please help
