Hi all, I have battery powered 24vdc circuit powering a resistive load (R1). I also have a seperate 12vdc battery powered circuit powering another resistive load (R2). As you can see from the schematic I have taken a conductor from the positive of the 24vdc battery and a ground from the 12vdc battery across a capacitor which is switched into R4.
My question is, firstly can I use the positive of one circuit and the ground potential from a separate circuit across a capacitor? Secondly if I can, do I need the same voltage potential from both sides?
What I mean by that is could I step up the 12vdc circuit to 24v with a transformer then bridge rectify it back to dc so I have the same potential across the cap.
Lastly, if I can do this, could I get rid of C1 altogether and just drive R4 with a positive 24vdc from one circuit and the ground from the other circuit which is now transformed and rectified into 24vdc? Thanks in advance.
