i'm estimating about 400$ worth of components.
to run 16 KW from 100vac to 800 vac, then back down to 48 volts.
any thoughts?
is running 800 volts dc a problem?
cutting the voltage in half (+/- 200) doesn't really change the cost much at all.
i would estimate 300$ to run 8 KW from 100vac to 400 and back down to 56.
is this at all worth it?
things that would be required: intelligent turbine control.
getting the boost circuit self operational is easy, the dump load can be mounted on the tower.
--sending the turbine RPM down the tower to the dc-dc converter is required.
--setting the boost PFC system up to have a variable output voltage instead of a fixed voltage is an option.. this also reduces losses considerably.-- but it complicates the step down converter. --- actually, its not that bad, because as the bus voltage falls so does the available power, a 5:1 voltage variation is probably doable.
