Thank you for explanation..
I can find 3 phase rectifiers/voltage regulators online, but they are mostly made in china so im not sure about their quality.
-I will try with single coil/phase, first then and see how that works
-what you mean by large capacitor? Something like 2000-4000uF ?
I really do not know wich one i need.. and, I do not mind to buy larger one, or pay for quality, etc, just i do not want to buy wrong one and buy twice then
