DC / DC converter from 48 to 450V

Hi.

This is the situation:

- the 4 DC generator's are generating from 40 - 48V of output voltage ( conected together ).

- the expected amperage would be around 60A.

---------------------------------------------- Each generator is BLDC motor and the rotating speed of each one is around

400 RPM. On this speed he can produce around 800W. -------------------------------------------- The goal is to convert this output voltage in the range between 450 - 500V and to keep this voltage on this level, regardless on generator production.

400-500V is range needed to run motor controler but i have to have some fixed voltage ( in this range ).

Suggestions how to make this ?

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?

** Nit pick for Mr Toothpick:

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.

**Correct. This part is done.

---------------------------------- 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.

** Piss off FOOL.

** Not a BLDC motor as you posted an then SNIPPED !!
** That is all new - you vile liar.

** Go away - you retarded IMBECILE .

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.
