Battery charger

Hello everyone ,
I would like to know any information on how to build a custom 12 vdc battery charger for a sine wave generator project that I have been working on for the past three months . This project has ten new batteries and power is converted from two 6000 watt inverters , I know that I can just go out and purchase one , but this whole project is built from scratch and I would like to build my own charger .
I would gladly appreciate any advise anyone can give .
Thanks so much ,
John Sherrer ,
Tampa Florida .

Is what you're building basically a 12Kw standby power system,simular to a large UPS for computer applications?

Doc here,

What type of battery will you be charging? (It makes a difference)

And what is the total AC draw you will require for the charger...

What are the DC requirements?

Cheap and dirty, (like a full wave bench supply) you will need a transformer equal to the task of the output, current wise, a proper fuse, a switch , "On Off" for the AC side, A Full wave Diode bridge, a couple of 0.1 caps for ripple bypass to ground, at LEAST 1 electrolytic Cap for filtering at about 100 WVDC, A Bleeder resistor on the DC output, A zenier Diode for DC polarity protection, a couple of pilot lamps for charge/draw states, a zip chord for AC input, Volt and amp gauge for the DC output..a box to put it all in..Prepunched circuit board.

Choices are dependent (values) on your output requirements..

This is just a cheap setup, you can go more exotic with op amp sensors, Voltage regulators (depending on current draw, and voltage required) automatic switching and the like..

Really need to know more about the specifics to narrow it down more for you..But the charger isn't hard to build if you have some electronic skill level..
