Battery charger design for inverter battery

[babinton]

Hello, I am back again, I thank everybody for the help with my toroid transformer question. Now I am finished with that part of my design, however I have another question: Which is: What type of circuit should I used for the battery charger that I want to include in my inverter;

I want to use the inverter for off-line application and I don't want to use any bulky 50/60Hz transformer for stepping down the AC voltage for my battery charger circuit. I would like to use direct AC to DC conversion for the charger part.

so, please, I welcome any suggestion on the charger design (also, I want to include a charge monitor circuit in the charger in order to avoid damage to the battery due to overcharging)

which one of the following will be okay for the charger:
1) Buck converter (non isolated)
2) Fly-back converter (isolated)
3) circuit with IC regulator like adjustable IC regulators)

regards

I use battery charger on IR2153.
