CCCV lead-acid battery charger
Siddhat:
Hey guys!
I am working on a project that includes battery charging. I need to charge a lead acid battery using Constant Current Constant Voltage (CC-CV) algorithm. I've already designed a buck boost converter in order to implement the CC-CV algorithm. But after many days of research I did not find proper circuit diagram to implement the algorithm. How is such an algorithm implemented in the buck boost converter? Are there circuits to implement this algorithm or am I missing something?
Kindly appreciate your help!!

Too few conditions.
The secondary of the flyback topology only needs one circuit composed of LM358 to charge the lead-acid battery(3 paragraphs).

Google for a schematics of popular CC-CV converters. For example, for such wide-popular on ebay.

After days of searching and researching, google too seems like a small place!! I got the concept of CCCV but not the circuit.

I know about feedback and PI control but do not know how to implement it since there are too many design considerations. So, looking for a even better solution to design the circuit. How can op-amps be used?
