Hi all,
I am looking at building a DC supply from 240vac 50hz 7kw generator to 48-63vdc 2kw adjustable to about 1v steps.
I want charge a bank of 15 lifepo4 batteries from the generator and control the current input via voltage control. I don't think regulation is necessary as the batteries will do that. I have considered a motorized auto transformer but that would be too heavy. Another idea was using voltage drop across a diode, set up an array of diodes and SSRs.
I am looking for something that is cheap and simple. Anyone have any ideas on another approach?
