I am trying to build a rectifier for my prop-driven DCC remote. I know this is possible with the components I have, because I pulled them off the old dcc remote and verified that they work. I have four 1N5401 diodes and two 35v 2.2mF capacitors.
I am trying to rectify a 16VAC supply to at least 15VDC. This supply is wierd, though. It is rated for 16VAC, but my meter reads 21.8VAC. I suppose that I need to rectify 21VAC in reality. Should be no issue for my circuitry.
I ohmed out the board of the old remote, trying to find out how they placed their filter caps, but what I got clearly was not right. I have a simple schematic of what I think would work underneath the schematic I got from the old remote attached. What I need help with is getting the DC supply smoothed out enough that I can power a model train from it (through an L298N in order to generate DCC signals) and power a prop from a linear regulator.
It should be known that I only have a multimeter, no scope.
