Dear Ericgibbs,
My battery is 24V,45AH,SLA battery(Two 12V,45AH in series connected).. Each battery had an initial current upto 13.5A. I dont know how in this circuit they have controlled the current here..but i wish to have the current control to 7A because my transformer rating is 240VA(24V,10A). So can we do it with changing the pulse width of Lower mosfets for charging current 7A max?? My charging voltage will be 30V appx...The circuit works like boost circuit it seems..
