hello all, new guy here and this is my first post:
i am faced with a project which is a dc to dc converter, of the buck mode version.
first the parameters
i want to feed the converter with 120 vdc of moderate amperage or say 20 amps.
i want to take the output of the converter to charge a battery bank of either 12 volts or possibly 24, either of which will be large flooded cells of around a 1000amp/hrs for the 12volt or around half that for the 24 volt bank.
because this is a learning or experimental project i will be using salvage components most of which i have no idea the values of, such as large inductors.
however i will purchase needed components such as mosfets, and a microcontroller to do the triggering so to speak, pwm or somesuch.
so my question is, where do i find some decent schematics for such a buck converter,, i would like around 120amps at 24 or twice that for a 12 volt system.
any help or direction would be most appreciated
thanks
