Buck Boost Transformer


My question is if I produced 100 vac and 150 amps, out of a pma generator, could i use a transformer to switch the 100 vac to 120 vac and 150 amps to 125 amps?

What are you trying to generate 120 with a car alternator?

Yes, it's possible. Nothing is ever 100% efficient so count on 100A @ 120V. You'll lose a little bit of power as heat, and noise from the transformer.

I just have to ask: what kind of device do you have that is producing 150 amps@ 100 volts?

I didn't look at the following thoroughly but I believe they are proper.

here is another application chart. Didn't source the unit though.

PMA = Permanent-Magnet Alternator.

Likely a wind turbine or other homemade generating apparatus.

a wind turbine to crank it at 10k rpm? That would be some serious gearing. It would also take big prop to produce that much horsepower as well.

On top of everything else, don't know if the OP realizes this but you have to convert to DC and then back to AC so you will have a constant 60 Hz. You won't get that from a wind machine. The freq varies with the wind speed.

or a very sophisticated speed regulation system

At 10,000T/min that is heckva a speed is that straight DC or very high HZ ac unit ?? if that on AC side you are looking at 400 + HZ on that speed.

Merci,

Okay, a valid point, but 10K RPM after some gearing from a combustion engine is easily reasonable.

Livewire, What is your "prime mover"?
@ 10,000 rpm I hope the bearings are in perfect condition.
