hi ..

I need a simple circuit for AC to DC converter of 220 V AC to 15 V DC (current rating: 3A) using a transformer for charging my VRLA batteries.

Thanks in advance

Hi,
This would be the easiest setting. Now you have to decide how you want to control charging. For simple CV charging, you could use LM350 or something more efficient like L4964.
