    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

    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.

    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.?
