Battery Charger Help
Can anybody help me on designing the 48V/10A battery charger. It should have facility of short circuit protection, polarity protection and over charging protection. I have design one circuit that was for the 12V/10A. It works fine but with simple modifying the ckt the have design 48V but it gave problem....Can anybody help me on this. For designing the 12V charger I have used SCR. SO I expect the circuit for 48V also made from using SCR. Thanx in advance.
