Turbo charged alternators
Most of us here are aware of the working of superchargers and turbochargers.
Superchargers actually draw a portion of the crankshaft output to power themselves.
but turbochargers are an improvement, where instead of taking anything from the crankshaft, they power themselves from the waste gases(exhaust).
Similarly now if the alternators too were to be powered by the gas turbines, then wouldn't there be an increase in efficiency. ?
Besides this would also enable alternators to be mounted some distance away from the engine, which would reduce heating, and increase the alternator efficiency .
what is your take on this ?

white_hatAs far as i know,when alternator is working at low rpm, we need a higher initial current to produce enough electricity.
Turbocharger rpm can go upto 30000+, i dont think alternator can handle these higher rpms also. -

what happens if the rpm exceeds, the required value ? -

Stator and rotor windings will get damaged.zaveriwhat happens if the rpm exceeds, the required value ? -

for which we can use reduction gear boxes, but then that would complicate things.white_hatStator and rotor windings will get damaged.
