hello.
I have designed many push pull inverters using 3524, 3525. But i dont know how to design a battery charger. I found few charging circuits on internet. But, I am afraid of making those as i dont know the basic concept in charging a battery. I believe that if something goes wrong, the battery may explode. Is that true?
Anyway, I am attaching the picture and schematic of the charger. check those.
I have few questions about smps and a battery charger.
1. What actually happens in the feedback loop (optocoupler and FB pin of IC)?
does it control the duty cycle or shutdowns the ic?
2. How the smps controls the charging current?
3. What happens if the battery is left connected to the charging circuit for a long time?
4. A pot is given at the output section of smps (connected in series with regulator KA431). what is the use of it?
