DC / DC converter from 48 to 450V

You have 4 generators which produce 40 - 48 volts each at 15 amps each connected in parallel and all are driven at the same rpm by some method?

BLDC motors are ( the motor part - forget any electronics) are really * permanent magnet alternators*.

They typically produce 3-phase AC at a frequency proportional to the RPM.

Now, if somebody fits a 3-phase bridge rectifier inside - it becomes a DC generator with output voltage proportional to RPMs.

So, it seem that what you have is a permanent magnet, brushless, DC generator.

Thank you for reply.

---------------------------------- Each generator can produce 36V at 300 RPM's If i connect them together i can get 36 x 4 = 144V. As i written before, i can reach constant RPM regardles on load resistance.

--------------------------------- Back to the subject. I dont know if I could keep this voltage at all the time so i was thinking to create some electronic which could "accept" input range from 100 - 144V and transform this voltage to constant 450V. So, 100-144V input --> DC/DC converter --> 450V output

If someone want's to help please be so kind and write your suggestions. Btw. dont worry about transforing losts. This part is for now, not important.

Phil, I'm sorry to write this but you really need help. Help regarding anger management.

The question was quite simple, and if I describe it wrong, or if you don't know the answer, you don't need to reply. Did you have to write all those insults? I don't think so.

Anyway if someone knows what would be the easiest way to do this, please let me know.
