Well I was going to use said conversion technique because each decoder soaks ~500mA and needs at minimum 8 volts to work, prefereably somewhere in the +-15 to +-18v range. So if I wanted to run 4 -5 locomotives at a time, thats 6 amps minimum ability to the track (just to err on the side of caution.)There is no way to support this kind of power drain from the board itself (neither high enough voltage nor amperage), so either way I will have to use a booster of some kind. I chose the method above because there are already working solutions that use it. It sounds too like it works pretty well, but I really am not too familiar with other techniques for doing this kind of thing so I would be very grateful to see an example of a different method. I would assume that you would use PWM through an h-bridge rather than sending a digital high / low? I look forward to hearing your plan. Thank you!
