Mosfet boost converter (above 100 A)?

treez said:

sounds like you need fets in parallel. im guessing this is a solar converter?
so maybe you can do loads of mini boosts in parallel

how to connect them in parrallel?

if there is Mosfet boost converter circuit diagram that can output 12 volt 600 amp of current? /QUOTE]

I hope you understand your request. Let me explain;

1) 12v X 600A = 7200 watt output power.
2) I will sincerely doubt that, unless you are employing state of the art converters, that you efficiency can be greater than 80%, so the input power would be 7200/0.8 = 9000 watt.
3) Since it is a boost converter, the input voltage has to be lower than the output voltage. I will assume that your lowest operating voltage to be 8v.
4) Therefore you require to manage 9000/8 = 1125 amps input current.

Have you given a thought on the implications of carrying and handling that much current?
Do you understand the type of circuit protections which are required to clear a short circuit fault, from a source that can provide 1125 amp?
