Hi all,

I want to design a battery charger (SMPS) which will charge a 100Ah 12V battery in about 3 to 4 hrs.

Input: 160VAC - 240VAC
Frequency: 50Hz
Battery: Lead Acid 12V, 100Ah.
Charge Time: 3 to 4 hrs.

I made a charger earlier which take 8-10 hrs. to charge the battery but I require to charge within 4 hrs.

I was thinking of using pulse charging method. But I am not fully aware regarding the mechanism of rapid pulse charging method. Searching internet, I also could not gather adequate working knowledge. If anybody is willing to share knowledge or can provide some link, it will be of great help.
