I am reading your qn wrong I guess

What is your need do you need an inverter ckt? or a Charger Ckt?

Both operate differently and do inverse operation So pls be more clear in your qn

i need a circuit which invert 12vdc to 220vac and also charge my 12v battery like a ups

please mention the load such that inverter circuit will be considered ok.a simple ac to dc circuit with more amperes a battery can charged ok.like using lm317,lm350 as a voltage regulators.normal power supply design concept or else for perfect charging concept you need to adopt PWM concept to recharge your lead acid battery.

go for first transformer design then you need to select the Controller based or a simple Ic based inverter ahh. if it so you can find at Rickyes world on net their u can find the simple design of Inverter.if not ill be post on day after tomorrow on CE,because my design is at final state its of 300watt and 500watt inverter.

Hello Mate,
I have a doubt. If you have to simply charge laptop battery with a +12VDC battery, you can directly connect them using a series resistance why are you looking for an inverter.?
