original circuit design is from this yt vid: In the original video I cant seem to make the voltage limit part in my simulations so I just changed it to an op-amp comparator instead.

sorry forgot to put it, my question would be if I would scale this charger circuit to fit the specification of a 48vdc @30A charger from the original 12vdc should I just change the transformer to a 220 to 54V-30A and change the resistor values? are there any other things that I should consider when converting the original design like the capacitors, transistors and diodes
 

There’s not a lot of information here. I’m not going to watch a video. What’s the original output current? If it’s also 30 amps, then you’re asking to quadruple the power. You’ll have to change more than a transformer and some resistors.
