Looking to design a 48V/1KW or higher charger with switch(toggle) for lead acid or Li-Ion battery selection type.
Found one reference design from Infineon: https://www.infineon.com/cms/media/PMM_3dmodels/battery-charger-demoboard.html

infineon code availability is an issue. Any other company which has reference design for charger with selection option for both lead and Li-Ion battery?

 

What's your experience of high current SMPS design and engineering and knowledge of charging technology? This is not for a beginner and the reference circuits are just guidance not engineered solutions. I've designed/built a 24v 1.2kW LiFePO4 charger and its not for the faint-hearted!
