Hello Sk1, Mvs Sarma,
I was asking this question because I was not sure that a DC voltage (supplied by a battery or linear regulator) can charge a battery; most of the battery charger in the market are AC to DC converter, so I guess the DC output is not perfect it will contain some ripple; I was wondering if this ripple is needed to charge the battery?
so can a perfect DC source recharge a battery (for sure we will have to add a current control)? does this depend on the battery type? do you have any document you can share?
Thanks,
Ballimo
