Using a stepdown transformer on a turbine
« on: May 01, 2011, 11:49:51 PM »
I have a windblue 540 low wind turbine. It does not produce a lot of amps. The most I see out of it is about 1-4 amps but when it is spinning the voltage at open circuit goes up to all 30V easily. It is a 3 phase wind turbine.
This is my theory:
Run the 3 phase through a stepdown transformer. And when it produce voltage like 30VAC for eg. the transformer step it down to about 14VAC while increasing the current at the output so you have a lower voltage but a higher current going to the battery. With this method i would have a higher current going to my battery at all times.
Would my theory work?

I covered this in another post. Try into a 24 or 36 volt battery. If the maximum power improves in high winds then there is more to be had. it depends a lot on your blades and their matching.

I wouldn't use the transformer you would do better reconnecting the windings to IRP ( Jerry connection). For the transformer to work effectively it will need to be very oversized and underfluxed to keep the losses small enough not to mitigate any possible gain. It will need to be 3 phase or you will need 3 single phase ones. Just overkill for correcting a potentially useless alternator.Spend the money on some magnets and wire flog the windblue thing and build a decent axial flux machine fit well designed wooden blades and you won't look back.

Please consider keeping all your Windblue thoughts in one thread.

Posting a fresh thread for every thought is counter productive.

Thanks.
